Landslides in Asheville, North Carolina, are blocking roads and filling homes with debris days after Helen passed through the region as a post-tropical cyclone.

North Carolina’s transportation secretary urged people to stay off the roads due to widespread dangers.

Search and rescue efforts were still ongoing Tuesday in the city and mountains of hard-hit western North Carolina.

Conditions remained severe thanks to the estimated 40 trillion gallons of water that fell from the storm as it passed over the southeastern United States. Many areas of western North Carolina received nearly or more than 20 inches of rain in the three days the storm passed.

“The topography is already working against us because of the steep terrain,” said Asheville Fire Chief Jeremy Knighton. “You add dirt, rain, water, and it becomes a mess.”

“No matter who or where you are in western North Carolina, if you need help, we are working around the clock to reach you,” said North Carolina Gov. Roy Cooper.

The video shows widespread destruction that washed out roads and knocked out power, isolating local communities.

On Tuesday, the North Carolina National Guard was distributing 100,000 pounds of new relief supplies delivered by the Federal Emergency Management Agency.

There was no fuel in Asheville. Residents were seen bringing in fuel and water from outside the region to meet local needs, and FEMA continued to bring in food and water by truck and plane.

Cell phone service remained spotty Tuesday, making it difficult to communicate and contact people still missing. FEMA is working to deploy more Starlink satellite internet receivers in the region to provide better communications to emergency services.

More than 380,000 customers were still without power in western North Carolina as of Tuesday afternoon, according to Poweroutage.us.

A White House spokesman said President Joe Biden has ordered FEMA Administrator Deanne Criswell to remain in North Carolina until the situation is under better control.

The president was expected to visit North Carolina on Wednesday to survey the damage and receive briefings from state emergency management officials.

The disaster declaration issued over the weekend will allow residents of North Carolina’s 25 counties to apply for FEMA assistance, officials said.
