Late Sunday night, rescuers were searching for a 1-year-old child who had been swept away, WSOC reported, after a car was trapped by floodwaters from Richardson Creek on Pleasant Hill Church Road in Union County.

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

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

He said water and food would be flown into the city that is home to about 120,000 people.

Early Sunday morning, it wasn't flooding that affected the studios of WWAY-TV in Wilmington; rather, it was a tornado reported nearby that made employees clear the studio and seek shelter. After the storm passed, the station tweeted that everyone was OK and a small leak in the ceiling was the only damage.

The storm's rainy siege persisted Sunday in the Old North State, leaving entire towns swamped and residents needing rescue from their inundated homes.

Florence Survivors Wish They Evacuated

At 7:15 a.m. Friday morning, Florence made landfall at Wrightsville Beach with 90-mph winds, heavy surf and torrential rain that triggered flooding and knocked down trees and power lines. Many who chose to stay in their homes during the storm said afterward that they wish they chose to evacuate.

Among those who said they should've obeyed evacuation orders was Tom Ballance, a New Bern restaurant owner who rode out several previous hurricanes at his home on the Neuse River.

"I feel like the dumbest human being who ever walked the face of the Earth," Ballance told the AP.

Damaged Homes, Beach Erosion in Emerald Isle

The town of Emerald Isle, in Carteret County, said in a news release that several homes had blown-out windows and doors, others were damaged by falling trees and a "very small number of homes" had significant structural damage that made the house uninhabitable.

Low-lying homes on the Bogue Sound side of the island, which saw significant flooding, have water in lower levels. On the ocean side, the town has significant beach erosion and has lost most of the initial frontal dunes, the release said.

There are no known dune breaches, and the town's extensive system of dunes, promoted by significant beach nourishment efforts in the past, appears to have effectively protected the oceanfront structures and infrastructure.
