Asheville has been isolated after Helene wrecked roads and knocked out power and cell service

ASHEVILLE, N.C. (AP) — Floodwaters pushed by the remnants of Hurricane Helene left North Carolina’s largest mountain city isolated 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 a helicopter 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 supplies were being airlifted to that part of the state. Buncombe County officials said Interstate 26 between Asheville and South Carolina had reopened, but most other routes into the city were impassible.

Among those rescued from rising waters was nurse Janetta Barfield, whose car was swamped on Friday morning as she left an overnight shift at Asheville’s Mission Hospital. She said she watched a car in front of her drive through standing water and thought it was safe to proceed. But her car stalled, and within minutes water had filled her front seat up to her chest. A nearby police officer helped her to safety.
