In Wilmington , with roads leading in and out of the city underwater and streams still swelling upward, residents waited for hours outside stores and restaurants for basic necessities like water. Police guarded the door of one store, and only 10 people were allowed inside at a time.

Woody White, chairman of the board of commissioners of New Hanover County, said officials were planning for food and water to be flown into the coastal city of nearly 120,000 people.

“Our roads are flooded,” he said. “There is no access to Wilmington.”

About 70 miles (115 kilometers) away from the coast, residents near the Lumber River stepped from their homes directly into boats floating in their front yards; river forecasts showed the scene could be repeated in towns as far as 250 miles (400 kilometers) inland as waters rise for days.

Downgraded overnight to a tropical depression, Florence was still massive. But with radar showing parts of the storm over six Southeastern states and flood worries spreading into southern Virginia and West Virginia, North and South Carolina were still in the bull’s-eye.

Half way around the world, meanwhile, Typhoon Mangkhut barreled into southern China on Sunday after lashing the Philippines with strong winds and heavy rain that left dozens dead. More than 2.4 million people were evacuated from China’s southern Guangdong province ahead of the massive typhoon, the strongest to hit the region in nearly two decades.

In North Carolina, fears of what could be the worst flooding in the state’s history led officials to order tens of thousands to evacuate, though it wasn’t clear how many had fled or even could. The head of the Federal Emergency Management Agency, Brock Long, said officials were focused on finding people and rescuing them.

“We’ll get through this. It’ll be ugly, but we’ll get through it,” Long told NBC’s “Meet The Press.”

President Donald Trump said federal emergency workers, first responders and law enforcement officials were “working really hard.” As the storm “begins to finally recede, they will kick into an even higher gear. Very Professional!” he declared in a tweet.

The storm’s death toll climbed to at least 17 when a 3-month-old child was killed when a tree fell across a mobile home in North Carolina. Earlier, officials said three people died in separate, weather-related traffic accidents in South Carolina.

Victor Merlos was overjoyed to find a store open for business in Wilmington since he had about 20 relatives staying at his apartment, which still had power. He spent more than $500 on cereal, eggs, soft drinks and other necessities, plus beer.

“I have everything I need for my whole family,” said Merlos. Nearby, a Waffle House restaurant limited breakfast customers to one biscuit and one drink, all take-out, with the price of $2 per item.

Kenneth Campbell had donned waterproof waders intending to check out his home in Lumberton , but he didn’t bother when he saw the Coast Guard and murky waters in his neighborhood.

“I’m not going to waste my time. I already know,” he said.

As rivers swelled, state regulators and environmental groups were monitoring the threat from gigantic hog and poultry farms located in low-lying, flood-prone areas.

The industrial-scale farms contain vast pits of animal feces and urine that can pose a significant pollution threat if they are breached or inundated by floodwaters. In past hurricanes, flooding at dozens of farms also left hundreds of thousands of dead hogs, chickens and other decomposing livestock bobbing in floodwaters.

Stream gauges across the region showed water levels rising steadily, with forecasts calling for rivers to crest Sunday and Monday at or near record levels. The Defense Department said about 13,500 military personnel had been assigned to help relief efforts.

Authorities ordered the immediate evacuation of up to 7,500 people living within a mile (1.6 kilometers) of a stretch of the Cape Fear River and the Little River, about 100 miles (160 kilometers) from the North Carolina coast. The evacuation zone included part of the city of Fayetteville, population 200,000.

John Rose owns a furniture business with stores less than a mile (1.6 kilometers) from the river. Rain-soaked furniture workers helped him quickly empty more than 1,000 mattresses from a warehouse in a low-lying strip mall.

“It’s the first time we’ve ever had to move anything like this,” Rose said. “If the river rises to the level they say it’s going to, then this warehouse is going to be under water.”

Fayetteville city officials, meanwhile, got help from the Nebraska Task Force One search and rescue team to evacuate 140 residents of an assisted-living facility to a safer location at a church.

Rainfall totals were stunning.

In Swansboro, North Carolina, nearly 34 inches (85 centimeters) of rain had fallen by Sunday afternoon and 20 other places in North Carolina had at least 20 inches, according to the National Weather Service. Another 30 sites in North and Carolina had at least 10 inches (25 centimeters).

Water on the Cape Fear River near Chinquapin got so high that electronic instruments used to monitor flooding quit working after it became submerged, the U.S. Geological Survey said. The same thing happened on the Trent River.

Still, there was some good news: Power outages in the Carolinas and Virginia were down to about 580,000 homes and businesses after reaching a high of about 910,000 as the hurricane plowed into the coast. Utilities said some outages could last for weeks.

In Goldsboro, North Carolina, home of Seymour Johnson Air Force Base, roads that frequently flood were already closed Saturday by rushing water. Dozens of electric repair trucks massed to respond to damage expected to hit central North Carolina as rainwater collected into rivers headed to the coast.

Duke Energy said heavy rains caused a slope to collapse at a coal ash landfill at a closed power station outside Wilmington late Saturday, but there was no indication contamination had drained into the nearby Cape Fear River. The company initially estimated that about 2,000 cubic yards (1,530 cubic meters) of ash were displaced at the landfill, enough to fill about 180 dump trucks. Sheehan said that estimate could be revised.

Near the flooded-out town of New Bern , where about 455 people had to be rescued from the swirling flood waters, water completely surrounded churches, businesses and homes. In the neighboring town of Trenton, downtown streets were turned to creeks full of brown water.

The rain was unrelenting in Cheraw, a town of about 6,000 people in northeastern South Carolina. Streets flooded and Police Chief Keith Thomas warned people not to drive, but the local food and gas store had customers.

“As you can tell, they’re not listening to me,” he said. (AP)
