Superstorm Sandy leaves 18 dead in NYC NEW YORK Mayor Michael Bloomberg says the New York City death toll from superstorm Sandy is up to 18. The dead included two who drowned in a home and one who was in bed when a tree fell on an apartment. A 23-year-old woman died after stepping into a puddle near a live electrical wire. The misery of Sandy's devastation grew Tuesday as millions along the U.S. East Coast faced life without power or mass transit for days, and huge swaths of New York City remained eerily quiet. The U.S. death toll climbed to at least 48, many of the victims killed by falling trees, and rescue work continued. The storm that made landfall in New Jersey on Monday evening with hurricane force cut power to more than 8.2 million across the East and put the presidential campaign on hold just one week before Election Day. New York was among the hardest hit, with its financial heart closed for a second day. The storm caused the worst damage in the 108-year history of the city's subway system, and Bloomberg said it could be four or five days before the biggest U.S. transit system was running again. "This was a devastating storm, maybe the worst that we have ever experienced," Bloomberg said. But the full extent of the damage in New Jersey was being revealed as the day unfolded. Emergency crews fanned out to rescue hundreds. Superstorm Sandy: State-by-state snapshot Superstorm Sandy slams Northeast, triggers massive blackouts, flooding A hoarse-voiced New Jersey Gov. Chris Christie gave bleak news at a morning news conference: Seaside rail lines washed away. No safe place on the state's barrier islands for him to land. Parts of the coast still under water. Sandy's Aftermath: Severe damage along Jersey Shore "It is beyond anything I thought I'd ever see," he said. It is a devastating sight right now. The death toll from Sandy in the U.S. included several killed by falling trees. Sandy killed 10 people in New York City. It also killed 69 people in the Caribbean before making its way up the Eastern Seaboard. Airlines canceled more than 15,000 flights. New York City's three major airports remained closed. Some bridges into the city reopened at midday, but most major tunnels and bridges remained closed, as were schools and Broadway theaters. Sandy damage leaves NYC paralyzed The storm sent a nearly 14-foot surge of seawater, a record, coursing over Lower Manhattan's seawalls and highways and into low-lying streets. The water inundated tunnels, subway stations and the electrical system that powers Wall Street and sent hospital patients and tourists scrambling for safety. A large tanker ship ran aground on the city's Staten Island. Around midday, Sandy was about 120 miles east of Pittsburgh in Pennsylvania, pushing westward with winds of 45 mph, and was expected to make a turn into New York State on Tuesday night. Although weakening as it goes, the storm will continue to bring heavy rain and flooding, said Daniel Brown of the National Hurricane Center in Miami. Sandy also brought blizzard conditions to West Virginia and neighboring Appalachian states, with more than 2 feet of snow expected in some places. Sandy will end up causing about $20 billion in property damage and $10 billion to $30 billion more in lost business, making it one of the costliest natural disasters on record in the U.S., according to IHS Global Insight, a forecasting firm. Obama speaks at Red Cross on Sandy relief effort He suspended campaigning for a third day Wednesday, and planned to join Christie in viewing the damage in New Jersey. Obama, speaking during a stop Tuesday at Red Cross headquarters, warned the public that the massive storm that struck the East Coast "is not yet over." He said there were still risks of flooding and downed power lines. He called the storm "heartbreaking for the nation." The president offered his thoughts and prayers to those affected and told them "America is with you." He said he also told government officials coordinating the response that there was "no excuse for inaction." And he said he told governors in affected areas that if they get no for an answer, "they can call me personally at the White House." Republican challenger Mitt Romney resumed his campaign, but with plans to turn a political rally in Ohio into a "storm relief event." Water cascaded into the gaping, unfinished construction pit at the World Trade Center, and the New York Stock Exchange was closed for a second day, the first time that has happened because of weather since the Blizzard of 1888. The NYSE said it will reopen on Wednesday. A fire raged in a neighborhood Tuesday morning in the borough of Queens, near the Atlantic Ocean, with 80 to 100 homes destroyed but no deaths reported. In New Jersey, where the superstorm came ashore, Sandy cut off barrier islands, swept houses from their foundations and washed amusement pier rides into the ocean. It also wrecked several boardwalks up and down the coast, tearing away a section of Atlantic City's world-famous promenade. Atlantic City's 12 waterfront casinos came through largely unscathed. A huge swell of water swept over the small town of Moonachie, and authorities struggled to rescue about 800 people, some of them living in a trailer park. Police and fire officials used boats to try to reach the stranded. The massive storm reached well into the Midwest with heavy rain and snow. Chicago officials warned residents to stay away from the Lake Michigan shore as the city prepared for winds of up to 60 mph (96 kph) and waves exceeding 24 feet well into Wednesday. Curiosity turned to concern overnight as New York City residents watched whole neighborhoods disappear into darkness as power was cut. The World Trade Center site was a glowing ghost near the tip of Lower Manhattan. Residents reported seeing no lights but the strobes of emergency vehicles and the glimpses of flashlights in nearby apartments. Lobbies were flooded, cars floated and people started to worry about food. As Hurricane Sandy closed in on the Northeast, it converged with a cold-weather system that turned it into a monstrous hybrid of rain and high winds - even bringing snow in West Virginia and other mountainous areas inland. Just before it made landfall, forecasters stripped Sandy of hurricane status, but the distinction was purely technical, based on its shape and internal temperature. It still packed hurricane-force winds. While the hurricane's 90 mph winds registered as only a Category 1 on a scale of 5, it packed "astoundingly low" barometric pressure, giving it terrific energy to push water inland, said Kerry Emanuel, a professor of meteorology at MIT. NYU Medical Dean Robert Grossman said patients - among them 20 babies from the neonatal intensive care unit who were on battery-powered respirators - had to be carried down staircases and to dozens of ambulances waiting to take them to other hospitals. A construction crane atop a $1.5 billion luxury high-rise overlooking Central Park collapsed in high winds and dangled precariously. Thousands of people were ordered to leave several nearby buildings as a precaution. Bloomberg told reporters that the storm deaths were tragic but said the city pulled through better than some people expected, considering the magnitude of the storm. The mayor said: "We will get through the days ahead by doing what we always do in tough times - by standing together, shoulder to shoulder, ready to help a neighbor, comfort a stranger and get the city we love back on its feet."
