The National Weather Service has a flash flood watch in effect through Friday evening.
EMERGENCY evacuations have been ordered in a city of 80,000 people over fears a dam is about to burst.
Officials in Lynchburg, in south-central Virginia, pronounced an endangered dam as "stable and safe" Friday afternoon, hours after they had warned the dam faced "imminent failure".
LuAnn Hunt, a city spokeswoman, tells NPR that 94 people took shelter at a local high school that's serving as an evacuation center.
"Lynchburg received 1.35 inches of rain on Thursday and 2.00 inches so far this month", AccuWeather Meteorologist Brett Rathbun said.
But officials said they would like to get through another possible storm and re-evaluate the dam Saturday before giving residents the all clear to return home.
Speaking from Lynchburg, CBS's Chip Reid warned the eastern American city could be flooded within 7 minutes.
One to three more inches of rain are expected to fall Friday.
The National Weather Service said up to six inches (15 centimeters) of rain fell within hours, filling College Lake near Lynchburg beyond capacity.
The collapse of the dam would cause significant damage to homes and businesses.
Because the sediment from the city's runoff is trapped above the dam, the lake has dramatically reduced in size.
The City of Lynchburg has created an interactive map to see if you're in a potential flooding area should the College Lake Dam fail.
