Search-and-rescue teams who have already saved hundreds of people scoured the mountains of western North Carolina for more survivors, working amid washed-out roads, smashed bridges and felled power lines following Hurricane Helene.
The storm has killed at least 162 people in North Carolina, South Carolina, Georgia, Florida, Tennessee and Virginia, CNN reported, citing state and local officials, and the death toll is expected to rise once rescue teams reach isolated towns and telecommunications are restored.
The death toll rose after North Carolina's Buncombe County reported 57 dead on Tuesday, up from 40 a day earlier.
The mountainous area including the county seat of Asheville bore the brunt of the storm, which US Homeland Security Secretary Alejandro Mayorkas said was of "historic magnitude".
Recovery will involve a "multibillion-dollar undertaking" lasting years, Mayorkas told reporters at the White House.
President Joe Biden vowed to "jump start this recovery process" after speaking with governors and other leaders in the impacted areas.
"People are scared to death. People wonder whether they're going to make it. We still haven't heard from a whole lot of people. This is urgent," Biden said.
Hundreds of people have been reported missing, a number that is expected to decline as more telecommunications come back on line and emergency workers are able to get into remote areas.
The North Carolina National Guard has rescued over 500 people, deploying helicopters to ferry in supplies and rescue workers, rescuing survivors and pets along the way, Major General Todd Hunt told a separate press briefing.
Some locations of western North Carolina may have experienced a 5000-year event, so perfect were conditions to create maximum precipitation, said Tennessee state climatologist Andrew Joyner.
A storm prior to Helene sucked moisture from the Gulf of Mexico and saturated areas like Mount Mitchell, the highest point in the Appalachian mountains above hard-hit communities like Swannanoa and Black Mountain. Then Helene approached at the perfect angle to rise over the peak, intensifying rainfall.
"The event was a perfect storm," Joyner said.
Taylor Jones, director of Buncombe County Emergency Services, was surveying the damage in Swannanoa after Friday's flood that consumed several houses and large parts of a church.
"This is a true disaster," Jones said, speaking to resident Ryan O'Keefe.
"This is not going to be something that can be fixed right away. This is not a sprint. This is more like two or three marathons."
Power outages were down to 420,000 from a peak of one million in North Carolina with all but two hospitals in the west of the state back on commercial power, said state Health Department Secretary Kody Kinsley. Access to public drinking water systems was scarce.
In all 1.5 million homes and businesses in six states from Florida to West Virginia remained without power on Tuesday morning, according to the website Poweroutage.us.
