An abandoned car's hazard lights continue to flash as it sits submerged in a rising flood waters during pre-dawn hours after Hurricane Florence struck in Wilmington, North Carolina, U.S., September 15, 2018.

With Wilmington cut off from the rest of North Carolina by still-rising floodwaters from Florence, officials plan to airlift food and water to a city of nearly 120,000 people as rescuers elsewhere pull inland residents from homes threatened by swollen rivers.

The spreading disaster claimed additional lives Sunday, with at least 17 people confirmed dead, and the nation's top emergency official said other states were in the path this week.

"Not only are you going to see more impact across North Carolina, ... but we're also anticipating you are about to see a lot of damage going through West Virginia, all the way up to Ohio as the system exits out," Brock Long of the Federal Emergency Management Agency said Sunday on Fox News.

In Wilmington , the state's eighth-largest city, 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.

County commission chairman Woody White said officials were planning for food and water to be flown into the coastal city.

"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 inland as waters rise for days.

Downgraded to a tropical depression, Florence was still massive. Radar showed parts of the sprawling storm over six states, with North and South Carolina in the bull's-eye.

Meanwhile, half way around the world, 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.

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.
