A round of Friday evening thunderstorms have placed much of the D.C. region in danger of flooding until the early morning hours of Saturday.
The National Weather Service issued a flash flood watch for Northern Virginia, central Maryland and D.C. until 4 a.m. Saturday.
A flash flood warning was in effect for parts of northern and central Virginia, Prince George’s County in Maryland and the District. The warning, which included Stafford, Orange, Fauquier, Culpeper and Spotsylvania counties, was canceled after midnight.
A separate flash flood warning for northwestern parts of Charles County in Maryland as well as northeastern Stafford County and southeastern Prince William County in Virginia was also ended earlier after large storms swept through the area.

Additional warnings continued to come in throughout the night. One of which was a severe thunderstorm warning for most of northern Virginia, including parts of Stafford, Fauquier, Culpeper and Prince William counties, as well as the City of Manassas, until 9:45 p.m.
Earlier in the evening, a severe thunderstorm warning was issued for Anne Arundel, St. Mary’s, Calvert, Prince George’s and Charles County in Maryland until 8:30 p.m.
Storms could have wind gusts up to 60 mph and quarter-sized hail, according to the weather service.

The weather service said the most severe weather had begun to wind down around 7:20 p.m., but that the threat of floods remained.
“Severe threat is beginning to wind down, but an isolated severe storm is still possible over the next couple of hours. Flash flood threat on the increase through the evening,” the weather service said.
Storm Team 4 meteorologist Mike Stinneford said what remains of Laura — which battered Louisiana and Texas on Wednesday and Thursday — will likely bring storms to the region on Saturday.
“Showers and thunderstorms will continue tonight, and as the remnants of Laura combine with a cold front on Saturday, we will see showers and storms throughout the day, with a risk of severe weather and flooding rain,” Stinneford said.
