There’s plenty of fallout from the severe thunderstorm that rumbled through D.C. a couple of hours ago. As of this moment, Pepco is reporting about 73,000 power outages. It seems like Alexandria really got the worst of it; we’re hearing that traffic there is a total mess thanks to road blockages and traffic light outages. In addition, the Yellow and Blue lines are currently experiencing delays due to a broken canopy at the King Street station. Arrivals at National and Dulles are reportedly delayed of 75 to 90 minutes due to the thunderstorms. Several trees in the District are also down, and a tipster emails us to tell us that the George Washington Parkway is also closed in both directions right now due to downed trees. There are additional storm cells to the west of the District which might bring more lightning and rain our way tonight; if you’re driving this evening, be sure to exercise plenty of caution and be prepared for random delays.
