Houston (CNN) Harvey is no longer a hurricane, but life-threatening flooding continued in and around Houston on Sunday night as citizens with boats assisted authorities in search and rescue efforts. 
 
 Flooding from Tropical Storm Harvey is overburdening resources in the country's fourth-largest city, prompting authorities to call on volunteers with watercraft for help in rescuing those trapped in homes and buildings. 
 
 An immediate respite from Harvey's wrath seems unlikely to come. The National Weather Service calls the flooding "unprecedented," and warns things may become more dire if a forecasted record-breaking 50 inches of rain does fall on parts of Texas in coming days. In anticipation of a worsening situation, Dallas is turning its main convention center into a "mega-shelter" that can host 5,000 evacuees. 
 
 The rainfall threatens to exacerbate an already dangerous situation, as Harvey's rains have left many east Texas rivers and bayous swollen to their banks or beyond. 
 
 "The breadth and intensity of this rainfall are beyond anything experienced before," the weather service said. "Catastrophic flooding is now underway and expected to continue for days." 
 
 The storm killed two people in Texas, authorities said, and the death toll will likely rise. More than 1,000 people were rescued overnight, and Houston Mayor Sylvester Turner warned that some 911 calls are going unanswered as operators "give preference to life-threatening calls." 
 
 From 10pm Sat to 1pm Sun., Houston 911 received over 56,000 calls. During an average day, they usually handle about 8,000. #harvey — Houston OEM (@HoustonOEM) August 27, 2017 
 
 Here are the latest developments: 
 
 A woman who drove her vehicle into high water in Houston was killed, and fire killed a man in Rockport. 
 
 Several states and the US military are sending emergency workers and equipment to Texas. In Harris County, though, authorities are having issues mobilizing those resources. "We've requested boats, all the things that would normally happen in a well-planned response to an event like this, but they can't get here," Harris County Judge Ed Emmett said. 
 
 Dallas announced its plans to open a "mega-shelter" capable of accommodating 5,000 evacuees at the Kay Bailey Hutchison Convention Center. County officials, charitable groups and local hospitals are working to open the shelter by Tuesday morning. 
 
 While Turner warned the rain could exacerbate flooding for "four to five days," Federal Emergency Management Agency Director Brock Long said he expects his agency "is going to be there for years." 
 
 The Houston Independent School District has canceled school for the week. 
 
 Houston's George Bush Intercontinental and William P. Hobby airports are closed until further notice, officials said. Corpus Christi International reopened at 4 p.m. Sunday, officials said. Jack Brooks Regional Airport in Beaumont, Ellington Airport in Houston, Mustang Beach Airport in Port Aransas and McCampbell-Porter Airport in Aransas Pass are also temporarily closed, the Federal Aviation Administration says. 
 
 Ben Taub Hospital, which houses a Level I trauma center, is being evacuated after flooding in the basement "disrupted the power source," Emmet said. 
 
 316,000 customers have lost electricity, Gov. Greg Abbott said. 
 
 The Red Cross is serving about 130,000 meals a day, the governor said. 
 
 President Donald Trump will travel to Texas on Tuesday, press secretary Sarah Huckabee Sanders said.

 Among those stranded by the storm is Ify Echetebu, 30, who spoke to CNN from her aunt's house in Dickinson, not far from Galveston Bay. Along with her fiancé, grandparents, a friend and several teenagers, Echetebu is trapped on the second floor of the house as floodwaters creep up the staircase. She can see the rooftops of submerged cars in driveways, she said. 
 
 On the first floor, the water is up to her waist, she said. Emergency services know she and 10 others are holed up in the home, she said, but because emergencies take priority, she doesn't expect to be rescued until tomorrow, Echetebu said.

 "We're nervous to stay here, but we are sleeping in shifts," she said. "Now we're having to deal with sewage in the water, river water, bayou water, water moccasins, snakes, gators." 
 
 Not far away, a rescue operation saved 20 to 25 residents of La Vita Bella assisted-living facility in Dickinson. 
 
 "They were up to their waist," Galveston County Commissioner Ken Clark said. "If they were in a wheelchair, they could have been up to their neck." 
 
 Residents of a nursing home in Dickinson, Texas, were rescued Sunday. 
 
 After a record 22 inches fell on the county in one day, rescuers set out before dawn Sunday to save those who braved the storm. Officials quickly realized they did not have enough boats for the rescue operations and asked private boat owners to help, said County Judge Mark Henry, responsible for disaster response in the county. 
 
 As of Sunday evening, between 800 and 1,200 people had been rescued from their homes in Galveston County, Henry said. 
 
 As authorities warned people not to take shelter in attics, unless they have axes handy to break through their roofs, several residents provided CNN with their accounts of riding out the storm. 
 
 "We are still stranded in our home with little kids and the water keeps rising," Houston resident Janet Castillo said Sunday morning. "We have (tried calling several numbers), but their lines are all busy or they don't answer."

 Jake Lewis of New Braunfels, Texas, said he woke up to ankle-deep water in the Houston hotel where he is staying. 
 
 "We have nowhere to go," he said. "I have a 2016 Chevy Silverado and the water is up to the door panels. The water keeps rising." 
 
 One of two confirmed fatalities happened in Houston when a woman drove her vehicle into high water and couldn't make it across, city police said. She got out of her vehicle, was overtaken by floodwaters and drowned.

 In a Sunday news conference, Abbott said, "We want to stress when there is heavy rainfall and flooding, the importance of staying off the road. If you drive into water, you're taking your life into your own hands." 
 
 Portions of major highways, including Interstates 10, 45 and 610, were submerged and unnavigable. Houston resident Dion Laurent said the White Oak Bayou flooded I-10 and I-45.

 Harris County Sheriff Ed Gonzalez said he understands the compulsion to find safer ground, but urged people to think twice before venturing out into high water and to consider unforeseen dangers, such as manhole covers being lifted from their holes. 
 
 Lt. Craig Cummings of the Texas Department of Public Safety said attempts to drive to safety may be futile anyway, as it took him two and a half hours to drive 20 miles in Houston on Sunday. 
 
 "There's 60 barricaded locations as of midnight. Most thoroughfares are impassable. Several hundred structures are flooded, and we are expecting that number to rise," he said. 
 
 In Brazoria County, south of Houston, officials set up an evacuation route for all residents living west of State Highway 288 and south of State Highway 6, ordering them to "LEAVE NOW!" under a mandatory evacuation order. Those in need of shelter can take refuge in the Bell County Expo Center in Belton, officials said. 
 
 The 911 dispatchers in the nation's fourth-most populous city have received 2,000 requests for rescue, Mayor Turner said. Houston Fire Chief Samuel Peña said his department had responded to 2,500 calls and have about 1,000 more waiting to be serviced. 
 
 Gonzalez tweeted that many high-water rescues were performed overnight in Houston, some involving children or residents with medical issues, including one person suffering from cardiac arrest. Stranded residents were saved from vehicles on the highway. Airboats were employed in some instances, he said.

 Harvey blasted ashore as a Category 4 hurricane just north of Corpus Christi. It brought with it 132-mph winds but was quickly downgraded to a tropical storm. Still, it continued to spawn tornadoes and lightning. 
 
 A flash flood emergency was declared for sections of Houston, where more than 24 inches of rain fell in 24 hours, the National Weather Service said. 
 
 The weather service said maximum sustained winds Sunday would be near 45 mph. While Harvey could become a tropical depression by Sunday night, residents are warned to remain vigilant. 
 
 The slow-moving storm is expected to drop 15 to 25 inches of rain over the Texas coast through Thursday. Isolated storms could drop up to 50 inches of rain, the weather service said. 
 
 "What is unique in Harvey is that as the storm moved inland, a large high pressure built in to the north and, basically, the steering currents, which guide Harvey, collapsed," said CNN senior meterologist Dave Hennen. "This has caused the extremely slow movement of the storm, moving only around 60 miles, less than 2 miles per hour. This has allowed the bands of storms to move over the same areas over and over." 
 
 The weather service says rainfall of this magnitude "will cause catastrophic and life-threatening flooding." 
 
 Some residents are comparing Harvey to Allison, a storm that struck the Texas coast in 2001 and killed 23 people. 
 
 "Allison was bad -- really, really bad," Houston resident Pat Napolio said, "but if (the water) creeps up anymore, Harvey will surpass (Allison)." 
 
 Rockport hit hard 
 
 A damaged home sits amid floodwaters Saturday after Hurricane Harvey slammed Rockport, Texas. 
 
 Another fatality was reported in the battered coastal city of Rockport. A person died in a house fire during the storm, Aransas County Judge Burt Mills said Saturday. 
 
 Warnings of tornadoes, torrential downpours and potentially historic flooding means extra bad news for broad swaths of southeast Texas, already littered with uprooted trees, toppled signs, flagpoles snapped like toothpicks and homes missing rooftops and patches of brick walls. 
 
 Hurricane Harvey took the walls off many Rockport homes. 
 
 Additional fatalities were feared in Rockport, where an estimated 5,000 residents rode out the storm, Aransas County Sheriff Bill Mills said. 
 
 Brock Long, director of the Federal Emergency Management Agency, said that Harvey would leave areas "uninhabitable for weeks or months," echoing language last heard ahead of Hurricane Katrina in 2005. 
 
 "FEMA is going to be there for years," Long said. ||||| JP Morgan Chase Bank, N.A. Houston, TX ABA # 021000021 For credit to: Greater Houston Community Foundation A/C#: 849170287 For further credit to: Hurricane Harvey Relief Fund

 "We are getting calls from across the country and right here in our hometown, and the generosity of people who understand this disaster is truly amazing," Mayor Turner said. "Together we can make a difference to those who will need extensive help to get back on their feet once this storm is over." 
 
 Earlier Sunday, Abbott said the state activated 3,000 National Guard and State Guard members as a result of the storm damage. He also said 500 vehicles and 14 aircraft had been put into service. 
 
 Texas Gov. Greg Abbott says another 1,000 National Guard members will be sent to Houston on Monday as flooding from Harvey continues to ravage the area. The governor announced the move late Sunday on his personal Twitter account. 
 
 Meanwhile, officials in Fort Bend County, Houston's southwestern suburbs, late Sunday issued widespread mandatory evacuation orders along the Brazos River levee districts. County officials were preparing for the river to reach major flood stages late Sunday. County Judge Robert Herbert said at a news conference that National Weather Service officials were predicting that the water could rise to 59 feet, three feet above 2016 records and what Herbert called an "800-year flood level." Herbert said that amount of water would top the levees and carries a threat of levee failure. 
 
 Thousands of homes could be affected by the releases, CBS Houston affiliate KHOU-TV reports . 
 
 Harris and Fort Bend county officials said Sunday that residents around certain areas should be prepared for the influx of water that was scheduled to happen at Addicks around 2 a.m. local time Monday and a day later at Barker. Officials warned residents they should pack their cars Sunday night and wait for daylight Monday to leave. 
 
 Residents living around the Addicks and Barker reservoirs designed to help prevent flooding in downtown Houston, were warned Sunday that a controlled release from both reservoirs would cause additional street flooding and could spill into homes. Rising water levels and continuing rain was putting pressure on the dams that could cause a failure without the release. 
 
 he American Red Cross was expanding the shelter by the hour. Volunteers initially set out around 1,300 cots and quickly assembled more in anticipation of other evacuees arriving through the night. They have enough space and cots to house 5,000 people. 
 
 Hundreds of people affected by devastating flooding in Houston have flocked to a downtown showcase convention center-turned-emergency shelter. Many arrived Sunday carrying little more than what was in their pockets. Most are preparing for a stay of several days, as water rises inside their homes and roads remain impassable. 
 
 Some 269,000 homes and businesses were in the dark in Southest Texas early Monday due to Harvey, utilities reported. 
 
 Smith says the city's 911 emergency response system has been challenged by sharply increased call volumes since the tropical storm made landfall late Friday. 
 
 Public Information Officer Keith Smith also says Sunday that rescue efforts continue and now are focused on those who feel trapped inside a home or building. 
 
 Houston officials continue to urge people to shelter in place and stay off flooded roadways as Harvey continues to batter the nation's fourth-largest city. 
 
 The center says people in the upper Texas coast and in southwestern Louisiana should continue to monitor Harvey's progress. 
 
 The hurricane center says Harvey's center was expected to drift off the middle Texas coast Monday and meander offshore through Tuesday before beginning "a slow northeastward motion." 
 
 That means it remains virtually stalled near the coast and continues to drop heavy rain on the Houston and Galveston areas. In the past 48 hours, numerous spots in the region have measured more than 25 inches of rain. 
 
 The National Hurricane Center said in its 4 a.m. CDT update that the tropical storm still has sustained winds of up to 40 mph and is centered 20 miles east of Victoria, Texas, about 120 miles southwest of Houston. It continues to creep to the southeast at 3 mph. 
 
 Harvey continues to head back toward the Gulf of Mexico at a slow pace. 
 
 Edwards said life-saving efforts such as search and rescue and shelters will be needed, especially in southwest Louisiana where forecasters say 10 to 20 inches of rain could fall. 
 
 Gov. John Bel Edwards said he sent a letter to the White House requesting the initial disaster declaration for five parishes in southwest Louisiana, and could add more areas to the request later. 
 
 Louisiana's governor is asking President Trump for a federal emergency declaration for Louisiana since forecasters expect Harvey to cause significant damage in the state. 
 
 Those in need of assistance should visit www.disasaterassistance.gov if they have internet access or call 1-800-621-FEMA. 
 
 Long encouraged Americans who want to help storm victims to go to the website www.NVOAD.org to connect with National Voluntary Organizations Active in Disaster, which is coordinating donations and volunteers. 
 
 According to the latest forecast from the National Weather Service, the storm is expected to dump another 15 to 20 inches of additional rainfall on the region before it's over. 
 
 Duke said she will accompany President Trump as he visits Houston on Tuesday. 
 
 For now, she urged local residents to avoid calling 911 unless they were in need of urgent, immediate medical assistance. 
 
 Duke said emergency officials are currently focused on rescue efforts and plan to move into recovery mode later this week. 
 
 "We are not out of the woods yet," said Elaine Duke, Acting Secretary of the Department of Homeland Security. "Harvey is still a dangerous and historic storm." 
 
 "All disasters begin and end at the local level," he added. "All evacuation decisions are made at the local level in Texas." 
 
 When it comes to the emergency response and evacuations, Long said he believes local, state and federal agencies thus far have operated with the "best information that they had at the time." More widespread evacuations would have been "difficult" given the time frame, putting people at risk of becoming trapped in long lines of vehicles trying to escape rising floodwaters, which would have been worse than the shelter-in-place scenario playing out now. 
 
 Calling Harvey a "landmark event," Long said "you could not dream this forecast up." 
 
 In a Monday morning briefing, FEMA Administrator Brock Long said officials are expecting 30,000 people in emergency shelters. As many as 50 counties are feeling the impact of the storm. 
 
 The statement said the Department of Homeland Security and FEMA would coordinate disaster relief efforts "to save lives and to protect property and public health and safety, and to lessen or avert the threat of a catastrophe in the parishes of Beauregard, Calcasieu, Cameron, Jefferson Davis, and Vermillion." 
 
 A statement from the White House Monday said President Donald Trump has declared an emergency in Louisiana, authorizing federal assistance for Harvey relief efforts in the state. 
 
 Follow along below for live updates on the storm. All times are Eastern unless otherwise noted. 
 
 The director of the Federal Emergency Management Agency (FEMA), Brock Long, predicted that the aftermath of the storm would require FEMA's involvement for years. "This disaster's going to be a landmark event," Long said. 
 
 "The breadth and intensity of this rainfall is beyond anything experienced before," the National Weather Service said in a statement. 
 
 As the water rose, the National Weather Service issued another ominous forecast: Before the storm is gone, some parts of Houston and its suburbs could get as much as 50 inches of rain. That would be the highest amount ever recorded in Texas. 
 
 Judging from federal disaster declarations, the storm has so far affected about a quarter of the Texas population, or 6.8 million people in 18 counties. It was blamed for at least two deaths. 
 
 Rescuers had to give top priority to life-and-death situations, leaving many affected families to fend for themselves. And several hospitals in the Houston area were evacuated due to the rising waters. 
 
 Volunteers joined emergency teams to pull people from their homes or from the water, which was high enough in places to gush into second floors. The flooding from Harvey, which made landfall late Friday as a Category 4 hurricane and has lingered dropping heavy rain as a tropical storm, was so widespread that authorities had trouble pinpointing the worst areas. They urged people to get on top of their houses to avoid becoming trapped in attics and to wave sheets or towels to draw attention to their location. 
 
 The incessant rain covered much of Houston in gray-green floodwaters and turned streets into rivers navigable only by boat. In a rescue effort that recalled the aftermath of Hurricane Katrina, helicopters landed near flooded freeways, airboats buzzed across submerged neighborhoods and high-water vehicles plowed through water-logged intersections. Some people managed with kayaks or canoes or swam. 
 
 "We are not out of the woods yet," Elaine Duke, Acting Secretary of the Department of Homeland Security, said at a Monday morning briefing. "Harvey is still a dangerous and historic storm." 
 
 The National Weather Service says flooding isn't expected to peak until Wednesday or Thursday. 
 
 HOUSTON -- The remnants of Hurricane Harvey continued dumping historic levels of rainfall on the Houston area Monday morning as devastating floods swamped the nation's fourth-largest city. Rising water chased thousands of people to rooftops or higher ground and overwhelmed rescuers who could not keep up with the constant calls for help. 
 
 About 300,000 customers were without power statewide. Gov. Greg Abbott said it would probably be several days before electricity is restored. 
 
 One person was killed in Aransas County when in a fire at home during the storm, county Judge C.H. "Burt" Mills Jr. said. A second person died in flooding in Harris County, where Houston is located. 
 
 Harvey continues to cause "catastrophic flooding in southeastern Texas," the National Hurricane Center says. 
 
 The National Weather Service said catastrophic flooding in the Houston metropolitan area "is expected to worsen and could become historic in association with Harvey." 
 
 EMERGENCY MANAGEMENT HAS REQUESTED: IF HIGHEST FLOOR OF YOUR HOME BECOMES DANGEROUS...GET ON THE ROOF. #houwx #glswx #txwx #Harvey pic.twitter.com/rG3dsdQUxu 
 
 The National Weather Service Houston/Galveston said Emergency Management officials are requesting that people get on the roof of their home if the highest floor becomes dangerous. 
 
 In Houston, authorities were pleading with people not to leave their homes as a flood emergency was declared. 
 
 The U.S. Coast Guard says it has received more than 300 requests for urban search and rescue in the Houston area amid flooding from Harvey. The Coast Guard has five helicopters working the emergency calls and is asking for additional helicopters from New Orleans to help. 
 
 Great coordination between agencies at all levels of government. Continuing rains and flash floods are being dealt with. Thousands rescued. 
 
 "Great coordination between agencies at all levels of government," he tweeted Sunday morning. "Continuing rains and flash floods are being dealt with. Thousands rescued." 
 
 Mr. Trump has sent a flurry of tweets about the powerful storm, and has complimented the government's response to it so far. 
 
 I will be going to Texas as soon as that trip can be made without causing disruption. The focus must be life and safety. 
 
 President Donald Trump said in a tweet he will travel to Texas "as soon as that trip can be made without causing disruption." He added: "The focus must be life and safety." 
 
 "We're very appreciative of our fellow states as well as what the federal government has done," Abbott said. "I gotta tell you the Trump administration has provided us everything that we need ." 
 
 Abbott also applauded the efforts of the Trump administration. 
 
 "And so we are working on as many water rescues as we possibly can and trying to find ways to get people out of harm's way," Abbott said on "Face the Nation" Sunday, as catastrophic flooding hit Houston. 
 
 Texas Gov. Greg Abbott said "our first and foremost focus at this particular time is saving lives." 
 
 Houston Assistant Police Chief Larry Satterwhite said there has been an increase in calls from residents with flooded homes in the city's northeast, southeast and southwest sections. 
 
 Pena said his agency has made more than 250 water rescues, all of them people in vehicles, during a three-hour period overnight. 
 
 Houston Fire Chief Samuel Pena said that since midnight his agency has responded to more than 2,500 emergency calls and another 1,000 calls were waiting to be serviced. 
 
 All commercial operations at Hobby Airport have ceased until further notice. No flights in/out and roadways in/out are closed. 
 
 Commercial operations have ceased at both George Bush Intercontinental Airport (IAH) and William P. Hobby Airport (HOU) in Houston until further notice "due to severe weather," an alert said Sunday. "No inbound or outbound flights from either airport at this time. For flight details, rescheduling and waivers, please contact your air carrier."

 "This event is unprecedented & all impacts are unknown & beyond anything experienced," the National Weather Service tweeted Sunday. "Follow orders from officials to ensure safety." 
 
 Rainfall totals since Thursday evening have reached about 25 inches in south Houston. In Dayton, located 38 miles northeast of Houston, rainfall has already reached 27 inches. 
 
 The NWS says in a statement that "the breadth and intensity of this rainfall is beyond anything experienced before and is resulting in catastrophic flooding." 
 
 "We're in kind of unprecedented territory with this storm," Burke said. 
 
 NWS meteorologist Patrick Burke said rainfall totals will end up around 40 inches or more for Houston on average, but some isolated spots will see 50 inches or more. 
 
 The National Weather Service said some parts of Houston and areas just west of the city could get 50 inches of rain as Tropical Storm Harvey stalls over the state. It would be the highest ever recorded in Texas. 
 
 A tornado watch has been issued for parts of Louisiana and Texas until 2 AM CDT pic.twitter.com/U07kpmb05G 
 
 The agency has also been tweeting a series of tornado warnings for locations in Texas, including Humble, Moonshine Hill and Kingwood, among other areas. 
 
 The National Weather Service in Houston issued a tornado watch for parts of Texas and Louisiana. It said the watch is valid until 2 a.m. CT Monday. The alert warned of possible tornadoes, marble-sized hail and isolated winds up to 60 mph.

 Videos posted online Sunday showed flooding that resulted from Harvey after it dumped massive amounts of rain on southeast Texas. 
 
 Houston needs our prayers! Our TV station is evacuated. Headed back out in the field to help us get back on the air #Harvey #KHOU11 🙏 pic.twitter.com/roq8Q6xlZN 
 
 Rainfall totals climbed by the hour. Since Thursday, South Houston had received nearly 25 inches and the suburbs of Santa Fe and Dayton got 27 inches. 
 
 Staff at CBS affiliate KHOU-TV, broadcasting live coverage of the floods, had to evacuate after water started to gush into the building. The anchors and news operations at the station moved first to a second floor before finally abandoning the station. 
 
 "We are coordinating logistics with state and local officials, and once details are finalized, we will let you know. We continue to keep all of those affected in our thoughts and prayers," Sanders said in a statement. 
 
 White House press secretary Sarah Huckabee Sanders said President Trump will travel to Texas on Tuesday. 
 
 It warned that flying drones without authorization may violate federal, state, or local laws and ordinances. "Allow first responders to save lives and property without interference," the FAA said in a statement.

 Rosenberg police did not immediately provide additional details on the sinkhole, other than urging drivers to avoid the area. 
 
 Water could be seen filling the sinkhole as pieces of highway asphalt hung from the edge of the damaged roadway. 
 
 The 3900 block of FM 762 (in front of 24 HR fitness) has just collapsed. There is a massive sinkhole in the roadway. AVOID THE AREA! #Harvey pic.twitter.com/BJreUS1D9C 
 
 Rosenberg police on Sunday tweeted a photo of the gaping hole that spread across more than half of a two-lane highway -- Farm-to-Market 762. 
 
 Police say a sinkhole has opened on a Texas highway about 25 miles southwest of Houston as Tropical Storm Harvey dumps more rain on the region. 
 
 McLeod says the evacuations won't start until the water recedes from around the facility and will likely take several days. The hospital is part of the Texas Medical Center, and has 350 patients. 
 
 McLeod says the flooding resulted in only a small amount of water in the basement and did not affect the hospital's power supply. But shutting down the kitchen leaves the hospital with a limited supply of dry food for patients. 
 
 Bryan McLeod, a spokesman for Harris Health System, said Sunday that minor flooding in the basement of Ben Taub Hospital and a busted sewer pipe forced officials to close the kitchen. 
 
 The evacuation of Houston's main public hospital hasn't begun yet because it is surrounded by waist-deep water as a result of Tropical Storm Harvey. 
 
 "Many in our HISD family will be dealing with the task of cleaning up the damage Harvey left behind. As a result, all HISD schools and district administrative offices will be closed all week." 
 
 The Houston Independent School District announced Sunday that all schools will be closed from Monday, August 28 through Friday, September 1, due to damage from Tropical Storm Harvey. The district said in a statement that schools and offices are expected to reopen on Tuesday, Sept. 5. 
 
 The State has requested we prepare to open our Mega Shelter to receive coastal guests. The City plans to open it by Tuesday morning. 
 
 The city opened a third smaller shelter about 4:30 p.m. Sunday. About 415 evacuees are staying at the two other shelters, where they will remain for the time being. 
 
 The city, Red Cross, Dallas County, Parkland Hospital, the Salvation Army, Children's Hospital and other volunteer groups are coordinating the logistics of getting the shelter ready. 
 
 City Office of Emergency Management Director Rocky Vaz says the state made a formal request to open the convention center, which should be ready by early Tuesday morning. 
 
 Officials say the Kay Bailey Hutchinson Convention Center will open to evacuees on Tuesday morning. Dallas has three shelters currently open for evacuees, but the convention center will serve as a "mega shelter." 
 
 Dallas officials say they'll open the city's convention center to about 5,000 people who are fleeing the southern part of the state. 
 
 The city of Houston opened the convention center Sunday to people fleeing the flooding from Tropical Storm Harvey. 
 
 Asked if he wishes he'd have evacuated, Cain laughed and walked away. He said: "That's a no-brainer, brother." 
 
 William Cain says the water outside their home was in some spots several feet high. He says, "I live in a lake where there was once dry land." Water had started to come into their apartment, and they had already lost power. 
 
 She suffers from congestive heart failure - when the heart's pumping power is weaker than normal - and other illnesses. Her son, William, and 9-year-old grandson were waiting for her inside. Both were barefoot as well. 
 
 Patricia Cain entered the George R. Brown Convention Center barefoot and carrying two oxygen tanks. The first was empty. The second was given to her by the Houston Fire Department after the U.S. Coast Guard rescued her from her home. 
 
 The NFL's Houston Texans flew to Dallas after their preseason game Saturday in New Orleans instead of returning home and have said they'll stay there until conditions improve enough for them to come back to Houston. They'll practice at the suburban practice facility of the Cowboys on Monday and said they will provide details on their schedule for the rest of the week later. 
 
 The Rangers had been scheduled to head to Houston after playing Oakland to await the start of a three-game series with the Astros beginning Tuesday. Instead, they'll return to Dallas to await word on its status. The Astros are in Anaheim and also will fly to Dallas while a decision is made on when and where the series will be played. 
 
 The Houston Astros and Texas Rangers won't travel to Houston as planned after their games Sunday in California because of torrential floodwaters that have engulfed the city.

 "We were airlifting grandmothers and grandfathers," David Popoff of Dickinson County Emergency Management told The Daily News, who showed him the viral image. "These people have been evacuated." 
 
 Eighteen people were rescued, including 15 seniors, from the La Vita Bella living facility, a city official told The Galveston County Daily News . 
 
 Residents of a nursing home in Dickinson, Texas, were evacuated Sunday after a viral image showed them sitting in waist-deep flood waters . 
 
 Henry is appealing for volunteers to help staff rescue shelters and see to the needs of the 2,000 to 10,000 people that have sheltered in them. He says he appealed for state and federal help mid-morning Sunday, adding "we have gotten some help, but we still need more." 
 
 Henry says about 90 percent of the county's rescue calls have come from Dickinson. An appeal had been made through social media for assistance by private boat owners and their vessels, and 25 to 35 owners responded. 
 
 The area hardest-hit by floods has been Dickinson, a low-lying city of about 20,000 residents along Dickinson Bayou, where crews had to lead to safety 19 residents and five staff members from an assisted-living center flooded with waist-deep water. 
 
 Galveston County Judge Mark Henry said Sunday that about 22 inches of rain has fallen on the coastal county so far with another 10 to 15 inches still expected. 
 
 A Galveston County official says Harvey has caused unprecedented flooding and 800 to 1,200 residents have had to be rescued. 
 
 Zetterstrom says the dams will impound water for one to three months as water is gradually released. He adds that some neighborhoods on the fringes of the reservoir are likely to see some floods. 
 
 Zetterstrom says the water contained by the dams is "unparalleled in the dams' history." The waters are rising about 4 inches per hour. 
 
 Downtown Houston is 17 miles downstream from the dams, which were built during the 1940s in response to a 1935 flood that inundated much of downtown area. 
 
 Col. Lars Zetterstrom is commander of the Galveston District of the Corps of Engineers. He says water will be released from the Barker Reservoir and Addicks Reservoir very slowly on Monday morning to prevent uncontrollable flooding of downtown Houston and the Houston Ship Channel. 
 
 The U.S. Army Corps of Engineers plans to begin releasing water into Buffalo Bayou from two flood-control dams on the western outskirts of the city. 
 
 "The decision that we made was a smart one. It was in the best interest of Houstonians. It was the right decision in terms of their safety... absolutely no regrets. We did what was the right thing to do," Turner said. 
 
 The mayor also defended his decision not to order an evacuation. 
 
 In addition, 35 boats and 93 dump trucks were being used by the city for high water rescues. 
 
 Turner said 22 aircrafts were working to help identify people stranded on roofs. Sixteen of those aircrafts are from U.S. Coast Guard. 
 
 Turner said that so far only one fatality has been confirmed -- a woman who died Saturday evening after getting out of her car when it drove into a flooded street. 
 
 Houston Mayor Sylvester Turner said that as of 5 p.m. on Sunday, Houston police and fire departments had received nearly 6,000 calls for rescues and had rescued more than 1,000 people. Many of these rescues were of people trapped on their roofs or in their attics. 
 
 On Sunday, videos emerged showing dramatic rescues by the coast guard. A number of rescues by boat took place, but Morgan reports there are still many people unaccounted for. 
 
 CBS News' DeMarco Morgan is in Dickinson, Texas, where he met one family who was rescued by boat. They live in a two-story home and one of the homeowners said the water level was up to her chest. She said all the furniture was just floating on the first floor as the family took refuge in the second story. 
 
 More video from the U.S. Coast Guard has been released showing rescues from their helicopter. A Coast Guard MH-60 Jayhawk helicopter crew from Air Station Houston rescued five people from floodwaters in a southeastern Houston neighborhood Sunday:

 The clip shows a Coast Guard member airlifting various people (including a dog) into one of their aircraft. 
 
 The United States Coast Guard posted video online that showed various rescues Sunday from the aftermath of Hurricane Harvey. 
 
 The Coast Guard says they assess each call of distress and that those in medical need take priority, according to Adm. Karl Schultz during a late Sunday press update. 
 
 They say that rescues have been done from bridges, rooftops, attics and they will continue to respond to calls. 
 
 Officials from the Coast Guard said that 19 helicopters have been deployed, 250 people have been rescued. 
 
 Officials say to call 911 if there is an immediate threat or 311 if you need help relocating from your home, but not in immediate danger. 
 
 If you see this do not share, KENS-TV writes. The number belongs to an insurance group and not the National Guard. If you are in danger and call this number you will not be rescued. 
 
 The station adds that the post reads, "The National Guard is being deployed to our Texas area. If you find yourself in a state of emergency. Call 1-800-527-3907. Please copy, paste or share!!!!!!!!!" 
 
 Despicable! Please share this story so no one affected by #Harvey who needs help/support/rescue is taken in by this scam https://t.co/c50wbWVGJn 
 
 A scam targeting victims of Tropical Storm Harvey posted on various social media sites has gone viral, CBS affiliate KENS-TV reports . 
 
 The hurricane center says Harvey's center was expected to drift off the middle Texas coast on Monday and meander offshore through Tuesday before beginning "a slow northeastward motion." 
 
 That means it remains virtually stalled near the coast and continues to drop heavy rain on the Houston and Galveston areas. In the past 48 hours, numerous spots in the region have measured more than 25 inches of rainfall. 
 
 In its 10 p.m. CDT advisory, the National Hurricane Center reports the storm still has sustained winds of up to 40 mph and is centered 20 miles east of Victoria, Texas, about 120 miles southwest of Houston. It continues to creep to the east-southeast at 3 mph. 
 
 Tropical Storm Harvey continues to head back toward the Gulf of Mexico at a slow pace.

 7:50 p.m.: "Biggest concern" is the 20-30 inches of rain, Texas Gov. says 
 
 More than a foot-and-a-half of rain fell in just 24 hours in Victoria, Texas -- and by the time the storm is over, the city could get in only days the amount of rain it sees in one year, CBS News' Manuel Bojorquez reports. 
 
 Rain from Harvey not nearly finished 
 
 "Our biggest concern is the possibility of between 20 and 30 inches of rain in areas ranging from Corpus Christi over to Houston," said Texas Gov. Greg Abbott. "Because of the flooding, one of the top focal points that we are concerned about is ongoing rescue and recovery." 
 
 Angela and Mario Manzano are checking on the home they recently purchased. 
 
 "It's devastating because like I said, we're barely purchasing the home, we're still paying it off, to lose it now, it's going to be hard," Angela said. 
 
 Their home is in a low-lying area prone to flooding. 
 
 "If it was just the two of us, it would be different, but having our kids, that why we took, we just took the most important things -- our important documents and pictures that can't be replaced and that stuff," Angela said. 
 
 7:30 p.m.: Inside Rockport, the city in the eye of Harvey 
 
 
 
 Inside the city directly hit by Harvey 
 
 Ferocious winds and floodwater have left this quaint city on the gulf a disaster zone, CBS News' David Begnaud reports. Parts of the high school were torn to shreds. Harvey showed no mercy on the local First Baptist church. Some homes have collapsed into the water. 
 
 "We went upstairs and looked out the window and down the road here it was a sheer wall of water, like 100 mph it was crazy," said Tim Freiburger. His garage was lifted up and jammed against the side of the house. 
 
 "It was insane all you could do was just feel stuff pounding the house," he said. 
 
 Residents of this senior living complex were stranded when portions of its roof torn away and emergency workers were unable to respond at the height of the storm. 
 
 Nearly every police car in town has been damaged, but still officers were out Saturday, banging on doors, making sure no one was trapped. 
 
 When the hurricane made landfall here late Friday night, the city was under a mandatory evacuation. 
 
 "I'll take a while to get it all straightened backup," said Randy Bonnett, who has been through Texas hurricanes before but he says he will not forget Harvey. 
 
 "You got three hours of hell and then an hour lull and then three hours hell," Bonnett said. 
 
 7:10 p.m.: Millions in danger of potentially catastrophic flooding 
 
 
 
 Harvey churns over southeast Texas 
 
 Harvey is still going and it's not going anywhere for awhile, CBS News' DeMarco Morgan reports. There are over 1,000 people assigned to search and rescue operations. Near Corpus Christi on Saturday, the Coast Guard rescued 17 people whose vessels were in distress. The governor of Texas has issued a disaster declaration for 50 counties. Saturday morning, Galveston got pounded. 
 
 With the storm stalling out, now millions are in danger of potentially catastrophic flooding. More than three feet of rain could fall in some places. 
 
 "We are just getting into this so people need to understand that the longevity of this is gonna go thru the weekend and even into the early part of next week," said Jeff Linder with the Harris County Flood Control in Houston. 
 
 Nearly 300,000 power outages have been reported and Corpus Christi is under a boil water order. Incredibly, no fatalities have been reported yet. In Rockport, where the storm took a direct hit, ten people were injured when the roof of a senior housing complex collapsed, according to local media reports. Hundreds of people were evacuated from a hotel there last night.

 Harvey is now a tropical storm, the National Hurricane Center (NHC) says in its latest release. 
 
 Winds have slowed to 70 mph, down from a peak of 130 mph when Harvey made landfall late Friday. The storm is now located 45 miles north-northwest of Victoria, Texas, and moving at 2 mph. 
 
 But Texas isn't out of the woods yet. The NHC adds that an "extremely serious flooding event is unfolding" as the storm continues to drench the area in rain. Some areas have seen rainfall of up to 3 inches per hour at times. The threat of storm surge continues to threaten low-lying areas, as well. 
 
 1:39 p.m.: Texas attorney general warns against price gouging 
 
 Texas attorney general says Harvey is "probably the biggest storm in [Texas] history" 
 
 Texas Attorney General Ken Paxton joined CBSN to discuss Harvey, and warned potential price gougers from taking advantage of residents as flooding continues. 
 
 "Under Texas law, you're not allowed to massively increase your prices by more than 10 percent, [that's] the approximate number, when there's some type of crisis or catastrophe," Paxton said. "There's significant fines for that, up to $20,000 per incident. If you're doing that to somebody over 65, it could be up to $250,000." 
 
 Paxton said his office has received over 200 calls about potential price gouging. He said investigators have looked into instances of alleged price gougers charging nearly $100 for a case of water. 
 
 12:45 p.m.: Texas evacuates prisoners threatened by flooding 
 
 
 
 The Texas Department of Criminal Justice announced Saturday three prisons would be evacuated in Brazoria County, just south of Houston, as rainfall from Hurricane Harvey slams the area.

"Additional food and water has been delivered to the prisons receiving the displaced inmates."11:59 a.m.: Texas Gov. Greg Abbott warns of "ongoing danger" from flooding. 
 
 Texas Gov. Greg Abbott on the state's response to Hurricane Harvey 
 
 Texas Gov. Greg Abbott on Saturday said ongoing flooding in the wake of Harvey poses the greatest danger in the days ahead, as rescue efforts are already underway in the southeast part of the state. 
 
 The Republican governor told CBSN that the hurricane, which made landfall late Friday night as a Category 4 storm but has since been downgraded to Category 1, has caused "great devastation." As it moves slowly and unleashes devastating amounts of rain on the Texas coastline, Abbott says flooding is the greatest concern. Read the full story here.

 "Our high school is damaged. One of our learning centers is also damaged. We have businesses that are destroyed, we have homes that have been destroyed, and at the very least lives are disrupted," Wax said. 
 
 The mayor said, as of Saturday morning, there were no confirmation of any deaths, but said it was likely because the response teams haven't been able to survey the town completely. 
 
 He also warned residents to "stay in place," adding that it wasn't safe to return home. 
 
 "Stay in place, protect yourself. If you did evacuate, do not even attempt to go back," he said. "Stay away, let the first responders do their job." 
 
 10:55 a.m.: Harvey expected to weaken to tropical storm this afternoon 
 
 Catastrophic flooding predicted over the coming days

 Hurricane Harvey slams the Gulf Coast 
 
 CBS News correspondent Manuel Bojorquez joined CBSN from Victoria, Texas, with an update from the heart of the storm. Speaking from his hotel as Harvey's eyewall whipped palm trees in the background, Bojorquez reports Victoria has received more than 16 inches of rain in the past 24 hours. 
 
 His hotel began swaying in the wind early Saturday morning. The roof of a car dealership behind the hotel began flapping in the heavy winds, indicating the likelihood of extensive structural damage as Harvey swirls over Texas. 
 
 "The big concern is not only all this wind, but of course all of this rain," Bojorquez reports. "They're not expecting just inches of rain here. They are expecting to get up to 2.5 feet. And so the major flooding that will happen as a result of this hurricane is something that they will deal with for days to come here." 
 
 9:12 a.m.: Michio Kaku says "agony has just begun" 
 
 Michio Kaku on Hurricane Harvey: "Agony has just begun" 
 
 CBS News science contributor Michio Kaku joined "CBS This Morning: Saturday" to discuss the science behind Harvey and why it will continue to cause damage for days. 
 
 "First of all, if it lingers over the land, it could cause massive flooding. And then, watch out," he said. "If it goes back into the Gulf, it could get reenergized and create a second, even a third landfall. And so the agony has just begun with this hurricane of the decade."

 1:45 a.m.: "Boil water," Corpus Christi residents told 
 
 In Corpus Christi, the major city closest to the center of the storm, wind whipped palm trees and stinging sheets of horizontal rain slapped against hotels and office buildings along the city's seawall as the storm made landfall. Boats bobbed violently in the marina. It was too dark to tell whether any boats had broken their moorings. 
 
 City officials notified residents to "boil their water prior to consumption (e.g., washing hands/face, brushing teeth, drinking, etc)" to kill all potentially harmful bacteria and other microbes. "Water for drinking, cooking and ice making should be boiled and cooled prior to use for drinking water or human consumption purposes. The water should be brought to a vigorous rolling boil and then boiled for two minutes." 
 
 1:15 a.m.: Early details emerge from Rockport 
 
 Rockport, Texas, a coastal city of about 10,000 people some 30 miles northeast of Corpus Christi, was directly in the path of Harvey when it came ashore. The city had peak wind surges of more than 125 mph, according to the National Weather Service. 
 
 Volunteer Fire Department Chief Steve Sims said there were about 15 firefighters at the city's fire station waiting for conditions to improve enough for their vehicles to safely respond to pleas for help. "There's nothing we can do at this moment. We are anxious to get out there and make assessments, but we're hunkered down for now," Sims said, according to an Associated Press report. 
 
 Fire Department spokeswoman Gillian Cox told the Corpus Christi Caller-Times that the roof of Rockport's high school has partially caved in. But Cox says social media posts that the school has "disappeared" are inaccurate. 
 
 Rockport City Manager Kevin Carruth told the newspaper that the courthouse also sustained major damage. Carruth said a cargo trailer was halfway in the building. 
 
 Earlier Friday, Rockport Mayor Pro Tem Patrick Rios offered ominous advice, telling a local TV station that those who chose to stay put "should make some type of preparation to mark their arm with a Sharpie pen," implying doing so would make it easier for rescuers to identify them.

 12:30 a.m.: Facebook activates "Safety Check" feature 
 
 Facebook has activated its Safety Check feature for Hurricane Harvey, allowing Facebook users to inform friends and family of their whereabouts during the weather emergency. 
 
 Facebook users can also find the feature on their smartphone apps. As CBSNews.com sibling site CNET explains: "Safety Check is now integrated into the mobile apps, meaning you can manually notify friends of your status as well as follow crises worldwide and even offer support. The only trick is finding it. When Facebook does a server-side activation, you'll usually see a notification right at the top of the app. But if you want to access the feature yourself, it requires a bit of menu-diving." 
 
 Here's a primer from CNET on how to find the feature on Android devices and iPhones.

 Trump prepares for first major natural disaster as president 
 
 Hurricane Harvey will be the first major natural disaster of President Trump's administration. The White House is saying FEMA has changed since the organization's dismal response to Hurricane Katrina in 2005, CBS News' chief White House correspondent Major Garrett reports. 
 
 The failures of Katrina haunt emergency planners to this day, so much so, White House Homeland Security Adviser Tom Bossert felt compelled to say "now is not the time to lose faith in your government institutions." 
 
 "All the mayors and governors saw what happened at Katrina and they're not gonna let that happen," says David Paulison, who headed FEMA after Katrina and until 2009. He says that Katrina changed management procedures. 
 
 "Before we waited for the local community to become overwhelmed before the state stepped in, and waited for the state to become overwhelmed before the federal government stepped in," Paulison tells Garrett. 
 
 7:40 p.m.: FEMA urges residents to follow future orders 
 
 Federal Emergency Management Agency (FEMA) officials are encouraging residents and visitors in Hurricane Harvey's path to follow directions from local and state officials.

"Know your threats, heed the warnings, and if you're in the path of the storm, ensure your family is prepared for possible prolonged disruptions to normal services." 
 
 The agency has set up bases near Seguin, Texas, and areas closer to the storm's path to store supplies including more than 96,000 liters of water, 306,000 meals and 4,500 tarps and blankets, the Associated Press reports. State and local officials will be responsible for distributing the materials as needed. 
 
 7:20 p.m.: 20-30 inches of rain expected in Victoria, Texas 
 
 Hurricane Harvey could dump feet of rain in Texas 
 
 Victoria, Texas, is about 20 miles from the coast, but the distance is not expected to shield it from the worst impacts of Hurricane Harvey. Aside from winds up to 105 miles per hour, the biggest threat is the rain, CBS News' Manuel Bojorquez reports. 
 
 Victoria is in the bull's eye of Hurricane Harvey's rain, with 20-30 inches expected over the next 72 hours. that's a year's worth of rain for this city. 
 
 The flooding is expected to be worse than Victoria's 1998 disaster. 
 
 "We've never seen a forecast for that kind of localized rain, and I've been working hurricanes and emergencies here for several years. It's the most dangerous forecast we've ever seen," said O.C. Garza the Victoria Office of Emergency Management.

 The National Weather Service says winds could leave homes uninhabitable for weeks or even months. Storm surge could reach 12 feet -- that's strong enough to wash away vehicles, Begnaud reports. 
 
 Fears of a power outage forced the sickest babies at a children's hospital to be moved out of the hurricane's path. Others are heeding the warnings and evacuating on their own. 
 
 7:02 p.m.: Hurricane Harvey upgraded to Category 4 storm

 6:09 p.m.: Houston officials resist calls for evacuation 
 
 Houston is bracing for dozens of inches of rain, but officials are urging residents to stay put. 
 
 Judge Ed Emmett, Harris County's top official, said "no mass evacuations" would be called because the hurricane would not "directly" hit the area. 
 
 "Always say run from water, hide from wind, we mean storm surge, not rain. [It's] not the kind of water we would ask people to evacuation from," Emmett said. 
 
 Mayor Sylvester Turner also urged residents to stay off roads and in their homes. Turner said there might be "greater danger" in having residents who don't need to be evacuated onto roads that could possibly flood, the Associated Press reports.

 He added, "You don't want to put yourself in a situation where you could be subject to a search and rescue." 
 
 3:00 p.m.: Hurricane Harvey reaches Category 3 
 
 Harvey became a Category 3 hurricane Friday afternoon, with sustained winds of 120 miles per hour, the National Hurricane Center said in an advisory.
– One of the most widely circulated images to come out of the Texas flooding on Sunday showed several elderly residents of a nursing home sitting in waist-deep water. "Need help asap emergency services please RETWEET," tweeted Timothy McIntosh. That's exactly what people did, and Galveston County Daily News reports that 15 elderly residents and three others from the La Vita Bella nursing home in Dickinson were rescued from the facility within hours. "We were air-lifting grandmothers and grandfathers," says the chief of emergency management in Dickinson. The New York Daily News provides background on the tweet. McIntosh lives in Tampa, Florida, but his mother-in-law in Texas, Trudy Lampson, owns the nursing home and sent the image to him and his wife. He quickly put it online. "Thanks to all the true believers that re-tweeted and got the news organizations involved," McIntosh wrote in a follow-up tweet after the rescue. "It pushed La Vita Bella to #1 on the priority list." The myth-busting site Snopes looked into the veracity of the image and reports nothing fishy about it.
