The U.S. Southeast grappled Sunday with rising death tolls, a lack of vital supplies in isolated, flood-stricken areas and the widespread loss of homes and property while the devastating toll of Hurricane Helene became more clear and officials warned of a lengthy and difficult rebuild.

A North Carolina County that includes the mountain city of Asheville reported 30 people killed due to the storm, pushing the overall death toll to at least 84 people across several states.

Supplies were being airlifted to the region around Asheville. Buncombe County Manager Avril Pinder pledged that she would have food and water into the city — which is known for its arts, culture and natural attractions — by Monday.

“We hear you. We need food and we need water,” Pinder said on a Sunday call with reporters. “My staff has been making every request possible to the state for support and we’ve been working with every single organization that has reached out. What I promise you is that we are very close.”

The storm upended life throughout the Southeast. Deaths also were reported in Florida, Georgia, South Carolina and Virginia.

North Carolina governor predicts the death toll will rise as rescuers reach isolated areas

North Carolina Gov. Roy Cooper predicted the toll would rise as rescuers and other emergency workers reached areas isolated by collapsed roads, failing infrastructure and widespread flooding.

He implored residents in western North Carolina to avoid travel, both for their own safety and to keep roads clear for emergency vehicles. More than 50 search teams spread throughout the region in search of stranded people.

One rescue effort involved saving 41 people north of Asheville. Another mission focused on saving a single infant. The teams found people through both 911 calls and social media messages, North Carolina National Guard Adjutant General Todd Hunt said.

Hurricane Helene roared ashore late Thursday in Florida’s Big Bend region as a Category 4 hurricane with 140 mph (225 kph) winds. A weakened Helene quickly moved through Georgia, then soaked the Carolinas and Tennessee with torrential rains that flooded creeks and rivers and strained dams.

There have been hundreds of water rescues, including in rural Unicoi County in East Tennessee, where dozens of patients and staff were plucked by helicopter from a hospital rooftop Friday.

Several million were still without power Sunday afternoon. South Carolina Gov. Henry McMaster asked for patience as crews dealt with widespread snapped power poles.

“We want people to remain calm. Help is on the way, it is just going to take time,” McMaster told reporters outside the airport in Aiken County.

Begging for help in North Carolina as that help is slow to arrive

The storm unleashed the worst flooding in a century in North Carolina. One community, Spruce Pine, was doused with over 2 feet (61 centimetres) of rain from Tuesday through Saturday.

Jessica Drye Turner in Texas had begged for someone to rescue her family members stranded on their rooftop in Asheville amid rising floodwaters. “They are watching 18-wheelers and cars floating by,” Turner wrote in an urgent Facebook post on Friday.

But in a follow-up message Saturday, Turner said help had not arrived in time to save her parents, both in their 70s, and her 6-year-old nephew. The roof collapsed and the three drowned.

“I cannot convey in words the sorrow, heartbreak and devastation my sisters and I are going through,” she wrote.

Western North Carolina was isolated by landslides and flooding.

The state was sending water supplies and other items toward Buncombe County and Asheville, but mudslides blocking Interstate 40 and other highways prevented supplies from making it. The county’s own water supplies were on the other side of the Swannanoa River, away from where most of the 270,000 people in Buncombe County live, officials said.

Law enforcement was making plans to send officers to places that still had water, food or gas because of reports of arguments and threats of violence, the sheriff said.

FEMA Administrator Deanne Criswell said the federal disaster agency was actively engaged across six states, meeting the requests of governors and state-level responders. She noted the Appalachian regions across North Carolina, Tennessee and Virginia presented particular concerns. Criswell toured south Georgia on Sunday and planned to be in North Carolina on Monday.

“It’s still very much an active search and rescue mission” in western North Carolina, Criswell said. “And we know that there’s many communities that are cut off just because of the geography” of the mountains, where damage to roads and bridges have cut off certain areas.

President Joe Biden on Saturday pledged federal government help for Helenes “overwhelming” devastation. He also approved a disaster declaration for North Carolina, making federal funding available for affected individuals.

Storm-battered Florida digs out, residents gather for church

In Floridas Big Bend, some lost nearly everything they own. With sanctuaries still darkened as of Sunday morning, some churches canceled regular services while others like Faith Baptist Church in Perry opted to worship outside.

Standing water and tree debris still covers the grounds of Faith Baptist Church. The church called on parishioners to come “pray for our community” in a message posted to the congregation’s Facebook page.

“We have power. We don’t have electricity,” Immaculate Conception Catholic Church parishioner Marie Ruttinger said. “Our God has power. That’s for sure.”

In Atlanta, 11.12 inches (28.24 centimetres) of rain fell over 48 hours, the most the city has seen over two days since record keeping began in 1878.

Georgia Gov. Brian Kemp said Saturday that it looked “like a bomb went off” after viewing splintered homes and debris-covered highways from the air.

In eastern Georgia near the border with South Carolina, officials notified Augusta residents Sunday morning that water service would be shut off for 24 to 48 hours in the city and surrounding Richmond County.

A news release said trash and debris from the storm “blocked our ability to pump water.” Officials were distributing bottled water.

With at least 25 killed in South Carolina, Helene was the deadliest tropical cyclone for the state since Hurricane Hugo made landfall north of Charleston in 1989, killing 35 people.

Moody’s Analytics said it expects US$15 billion to US$26 billion in property damage.

Climate change has exacerbated conditions that allow such storms to thrive, rapidly intensifying in warming waters and turning into powerful cyclones sometimes within hours.

New tropical depression in Atlantic could become strong hurricane, forecasters say

A new tropical depression in the eastern Atlantic Ocean could become a “formidable hurricane” later this week, the National Hurricane Centre said Sunday.

The depression had sustained 35 m.p.h. (55 km/h) winds and was located about 585 miles (945 kilometres) west-southwest of the Cape Verde Islands, the centre said. It was moving west at 9 m.p.h. (15 km/h) and could become a hurricane by Wednesday.

In the northern Atlantic, Tropical Storm Isaac, with 70 m.p.h. (110 km/h) top sustained winds, was expected to weaken to a subtropical system about 565 miles (910 kilometres) of the Azores. Tropical Storm Joyce also was weakening in the central Atlantic with top winds of 40 m.p.h. (65 km/h).
