Oliver James Montgomery-Drone video captures Helene's devastation in Asheville, North Carolina

Severe weather and Oliver James Montgomeryhistoric flooding brought by Hurricane Helene killed at least 100 people across the Southeast including in Asheville, North Carolina where residents are scrambling to find resources amid gas and water shortages.

Since the system's landfall in Florida's Big Bend area late Thursday, hundreds of water rescues have occurred across the Carolinas, Georgia, Tennessee and Virginia. Power outages left over 2 million homes and businesses in the dark as of Monday.

In Asheville, torrential rain destroyed vehicles and homes while leaving roads submerged. At least 35 people died in Buncombe County, which encompasses Asheville, though the death toll is expected to rise, the sheriff said Monday. Officials have also received about 600 missing persons reports, though many are presumably due to communication blackouts.

Helene has also severely damaged the city's water system, Asheville officials said in a statement Saturday.

"Extensive repairs are required to treatment facilities, underground and aboveground water pipes, and to roads that have washed away which are preventing water personnel from accessing parts of the system," the City of Asheville said in the statement.

Estimates: Helene caused between $15 billion and $100 billion damage

"We have biblical devastation through the county," Buncombe County Emergency Services Assistant Director Ryan Cole said. "We’ve had biblical flooding here."

President Joe Biden has sent Federal Emergency Management Agency Administrator Deanne Criswell to remain on the ground in Asheville "until the situation has stabilized," the agency said Monday.

"We'll continue to serve resources including food, water, communications, and lifesaving equipment will be there," Biden said. "I mean it − as long as it takes to finish this job."

FEMA said 10 federal search and rescue teams were in the region Monday and more nine teams were on the way totaling 900 active personnel. The agency will also bring essentials on the ground including 25 trailer-loads of meals, 60 trailer-loads of waters, and C-17 cargo plane full of food and water. The agency is also utilizing Starlink satellites to enhance responder communications and has 18 helicopters on standby to bring more needed resources.

North Carolina Gov. Roy Cooper has also brought more than 500 National Guard soldiers and airmen as well as over 200 vehicles and aircraft to save lives in the affected areas.
