Severe thunderstorm watches remain in effect for the Washington metro region through Saturday evening.
Residents should watch out for high and gusting winds. There have been sporadic reports of trees blown down by the storm.
Flooding will be a bigger concern through Sunday morning.
The National Weather Service has issued a flood warning for municipalities bordering the Potomac River in both Virginia and Maryland. The city of Alexandria has warned residents to be cautious of flooded roadways, and made sand bags available on Saturday. In Annapolis, Md., sand bags were also distributed.
Residents inland should also be wary, because creaks and steams may also swell and overflow their banks.
