Check here for the latest updates on the storms in the area.

Update 7:08pm

Storms continue to move into western Fairfax County from Prince William. Flash Flood Warnings remain until 8:45pm in Fairfax and Montgomery Counties. If you are in the D.C. metro, I would stay inside over the next hour or so until these storms end as there is still dangerous lightning across the area.

Large hail came down in Laurel tonight, as seen in this screenshot from a video sent in by Kate Gage.
