RALEIGH, N.C. — The remnants of Tropical Storm Bill moved from North Carolina into Virginia on Thursday after spawning tornadoes and pushing some already swollen lakes over their banks.

Several counties in both states were under flood warnings Thursday morning.

In North Carolina, a 10-year-old boy drowned in a rain-swollen creek, and at least three tornadoes touched down. No injuries were reported from the twisters, in the eastern half of the state.

Rainfall across North Carolina averaged 1 to 2 inches Wednesday, and all 500 campsites were under water at the already flooded Kerr Lake near the Virginia line. Fourth of July celebrations there were postponed until August.

High water at Claytor Lake in southwestern Virginia and Bluestone Lake in southern West Virginia forced the evacuation of three campgrounds late Wednesday night, state park officials said.

In North Carolina's mountains, Lake Toxaway had received 9.15 inches in a 24-hour period ending Wednesday morning, according to the National Weather Service.

A boy died at a Raleigh hospital after he was pulled from Holly Springs creek, which neighbors said is usually only a few inches deep. The boy, whose name wasn't immediately released, was playing with a friend when he fell into the gushing water and became lodged beneath a pipe, neighbors said.

Tornadoes in four counties caused minor property damage, turning a tree over onto a house near Fayetteville and blowing off a roof in Pitt County.

Another tornado, in the town of Ernul, leveled an old wooden barn and damaged the roof of 84-year-old Bernard Gaskin's home.

"It started tearing everything up," Gaskin told The Sun Journal of New Bern. "I heard the wind and everything just froze."

In the Florida Panhandle, two swimmers drowned off Panama City Beach in rough surf and dangerous rip currents, also remnants of Tropical Storm Bill, officials said.

A man helping two girls who got caught in a current died later at a hospital. The second victim was believed to be a teenage girl. At least five rescued swimmers also were taken to hospitals.
