A flood warning has been extended for some areas as rain is expected to continue to drench the D.C. area until late Monday morning.
The flood warning is in effect for Prince George's, Anne Arundel and Calvert counties in Maryland until 3:30 a.m. Monday and Charles County, Maryland, until 12:15 a.m.
Rain subsided for most of the area by about 8 p.m. but one last lighter band of showers will push through overnight, Storm Team4 said. Final rain tallies will range from 1 to 3-plus inches throughout the region.
Storm Team4 declared Sunday a weather alert day because the heavy rain made favorable conditions for flooding.
Flood watches were in effect for D.C. and many counties in Virginia and Maryland earlier Sundayin the day.
The Jefferson Davis Highway was closed in Woodbridge between Occoquan Road and Mary's Way, Prince William County police said.
Section A of the Billy Goat Trail has been closed due to high water levels on the Potomac River, and officials caution other trails and paths near the river may be unsafe.
Be cautious with driving, because the rain left high standing water, flooded roadways and low visibility.
More than an inch of rain fell on Washington, D.C., with consistent rainfall expected through the early afternoon.
Temperatures have been moderate to warm, with highs in the high 50s and low 60s.
Overnight, temperatures will drop. Monday will be mostly cloudy with temperatures staying in the 30s and 40s. You may see some showers in the morning.
