Floodwaters pushed by the remnants of Hurricane Helene left North Carolina’s largest mountain city largely cut off Saturday by damaged roads and a lack of power and cellphone service, part of a swath of destruction across southern Appalachia that left an unknown number dead and countless worried relatives unable to reach loved ones. The storm spread misery across western North Carolina and eastern Tennessee, where on Friday authorities used helicopters to rescue dozens of people from the rooftop of a flooded hospital. In North Carolina alone, more than 400 roads remained closed on Saturday as floodwaters began to recede and reveal the extent of damage. North Carolina Gov. Roy Cooper said that supplies were being airlifted to that part of the state. In Asheville, there was no cellular service and no timeline for when it would be restored. Residents were also directed to boil their water. Across the state line in Greene County, Tennessee, the threat of a stressed dam was easing on Saturday morning. The Tennessee Valley Authority, which had warned residents overnight that the Nolichucky Dam could breach, said Saturday morning that the river had crested and was receding. The TVA said the dam was intact and that crews were continuing to assess the dam. In northern Florida, Residents of a hurricane-struck community are clearing debris and recovering Saturday from the damage left by Hurricane Helene. Timmy Futch, who was born and raised in Horseshoe Beach, Florida, said this was the first time he had questioned whether it was worth weathering the storm, saying, "I don't know nothing but this place." The storm has been blamed for at least 52 deaths across five states, including 23 people in South Carolina and 11 in Florida. But the death toll is sure to rise as authorities continue to take stock of Helene's devastation. The hurricane roared ashore Thursday night as a Category 4 storm on Florida's Gulf Coast and then quickly moved Friday through Georgia, the Carolinas and Tennessee, uprooting trees, splintering homes and sending creeks and rivers over their banks and straining dams.
