Wilmington has been completely cut off by floodwaters and officials are asking for additional help from state law enforcement and the National Guard.

 

Woody White is chairman of the board of commissioners of New Hanover County. He said at a news conference Sunday that additional rainfall Saturday night made roads into the city impassable.

 

White says officials are planning for food and water to be flown to the county, although new distribution centers will have to be found because of all the rain in the northern part of the county.

 

Earlier Sunday, officials from the Cape Fear Public Utility Authority had said they were almost out of fuel for the water plant and might have to shut down. The utility later issued a release saying it had found additional fuel.

 

White says officials have asked Gov. Roy Cooper for additional aid.

North Carolina officials say large-scale search-and-rescue operations are underway in coastal areas as floodwaters from Florence spread across the state and road conditions worsen.

 

Michael Sprayberry is director of the North Carolina Division of Emergency Management. He said at a news conference that more than 1,000 responders were working with more than 200 boats to rescue people Sunday afternoon.

 

Officials are also delivering food, water and rescue vehicles to hard-hit areas.

 

The state's transportation secretary says 171 primary roads are closed, 100 more than a day earlier. Officials warned that problems would spread westward Sunday along with the remnants of the storm.

 

Gov. Roy Cooper says the storm has "never been more dangerous" than it is now for areas from Fayetteville and Lumberton, across the Sandhills and central part of the state into the mountains.

 

Around 15,000 North Carolinians are in shelters and about 700,000 were without power.
