5:15 PM Update Bob Ryan  Strongest storms with still threat of 1" hail now into Anne Arundel County.  Downtown DC almost 2" rain in one hour so reason for Flash Flood warning until 7PM  Other severe warnings in metro area until 5:45 PM.

5:03 PM Upate:  Those slow moving storms over the District, Montgomery, and Prince Georges counties have prompted a FLASH FLOOD WARNING until 7PM.  Some spots have seen between 1 and 2 inches of rain in the past hour, so be very cautious on the roadways and don't drive through standing water. 

5:00PM Update  Bob Ryan here New warnings for the line of strong thunderstorms moving through Prince Georges and Ann Arundel County.  History of hail and plenty of cloud to ground lightning so power outages likely.  These storms move into the Bay next 1-2 hours
