Heavy rains generated by the severe storm Alberto unleashed flooding in Virginia that washed out bridges, damaged homes, closed schools and transformed a normally peaceful creek into a raging river that swept away cars with people still in them. At least one person was killed and rescuers were searching for others.

Rescue crews searching in and around Ivy Creek found the body of one of two occupants of a Toyota Prius that was washed off the road Wednesday night, Albemarle County police said. A search for the second person was paused overnight because of dangerous conditions, officials said. Farther north in Madison County, the sheriff’s office said rescuers were searching for a female reported missing in water the night before.

The storm, already blamed for at least four deaths in the U.S. earlier in the week, was pushing across the Great Lakes on Thursday. But the National Weather Service said the potential for more rainfall and flash flooding would continue for the Southeast, the Ohio Valley and the mid-Atlantic through the end of the week.

Since making landfall on Memorial Day in the Florida Panhandle, Alberto’s heavy rains have been widespread, with flooding reported from Alabama through Tennessee, Kentucky, Illinois, the Carolinas and West Virginia.

In Albemarle County, the Prius and a second car were swept into Ivy Creek around 9:30 p.m. Wednesday. The occupant of one car was able to swim to a safe location, police said in a news release. But witnesses saw a man and woman get swept away as they climbed out of the Prius, Albemarle County Fire Rescue Chief Dan Eggleston said at a news conference.

“Ivy Creek is normally a very docile creek, but with 8 to 10 inches of rain ... it turned into a swollen, raging river. And It just tossed and turned both of those vehicles,” he said.

Authorities also responded to at least 10 other water rescues and received reports of damage to homes, the extent of which wasn’t immediately clear, Eggleston said.

Schools in the county were closed due to poor road conditions. Authorities throughout the region posted photos of washed-out roads and bridges, and they warned people to avoid unnecessary travel. One photo posted by the city of Charlottesville showed a partially submerged playground.

Elsewhere in the Southeast, the storms triggered floods and mudslides.

In the mountain town of Boone, N.C., one of those mudslides was blamed for a gas leak and explosion that destroyed a home Wednesday afternoon, killing two people.
