 In the early hours of Wednesday morning, officials in McDowell County reported widespread flooding after heavy rainfall of 4 to 6 inches over the past 24 hours, the National Weather Service said. "This is causing significant and life-threatening flooding countywide," it said. 
 
 The flooding was triggered by the soggy remnants of Alberto, the first named storm of the Atlantic hurricane season. 
 
 The flash flooding emergency expired at 10:30 a.m. Around the same time, officials lifted the mandatory evacuation order after deeming the dam safe. 
 
 Earlier, the National Weather Service said a flash flood emergency was in place for McDowell County, which includes the city of Marion, home to around 7,800 people, and Old Fort, population 900.

 Lake Tahoma is about five miles northwest of Marion, which is about 36 miles east of Asheville. 
 
 There were no casualties reported from the floods. North Carolina Gov. Roy Cooper said in a statement that two state Department of Transportation workers were swept away by a mudslide in McDowell County as they worked to clear debris from a previous mudslide, but they managed to stand on a truck that had fallen into the Catawba River until they were rescued. Cooper declared a state of emergency for western North Carolina on Wednesday.

 CBS affiliate WFMY-TV of Greensboro, North Carolina, reports a mudslide in Old Fort forced the shutdown of a portion of Interstate 40. Later, the North Carolina Department of Transportation said the right two westbound lanes and the left eastbound lane remained closed, probably until Friday afternoon. 
 
 WFMY-TV said western North Carolina communities were on high alert due to heavy rains and flash flooding and possible mudslides from Alberto. According to the AP, forecasters warned that the leftovers of the Atlantic hurricane season's first named storm were still capable of causing treacherous flooding as heavy precipitation spreads deeper into the nation's midsection. Flash flood watches were in effect for parts of several states from Alabama through Tennessee, Kentucky, Illinois, the Carolinas and Virginia and West Virginia. 
 
 Lake Tahoma is a private lake in the mountains of Western North Carolina, located in McDowell County.
– When you live near a major dam, the last thing you want to hear is that the integrity of it has been "compromised" by landslides. But that's exactly what residents living below North Carolina's Lake Tahoma were told late Tuesday in a tweet from a local National Weather Service account. "MANDATORY EVACUATIONS," the post read, with specifics on who exactly in McDowell County should be getting out. "ACT NOW TO PRESERVE YOUR LIFE!" NBC News reports the flash-flood emergency warning to thousands came after an engineer checked out the dam, and after heavy rain had caused "significant and life-threatening flooding" throughout the county, per the NWS. Weather.com says there were two landslides reported in the area, with local authorities noting the dam is in "imminent danger" of failing, per CBS News. Water was reported spilling out from the sides of the dam early Wednesday. "Floodwaters have reached levels not seen since the September 2004 floods associated with Hurricanes Frances and Ivan," the NWS says, per NBC. The communities of Marion and Old Fort are among those most severely affected. Heavy rainfall throughout several Southern states is linked to the storm Alberto, which took the lives of two South Carolina journalists Monday when a tree fell on their SUV.
