Power is being restored to the area after thousands were left without electricity in the wake of thunderstorms that hit the D.C. area Saturday night. Storms generated rainfall, dangerous lightning and some downed tree limbs. Montgomery County, Maryland, saw the worst of the outages — more than 1,000 remain without power shortly after 2 p.m., down from a high of 3,500 at 10:30 a.m. In neighboring Prince George’s County, more than 300 were without power. Several hundred more are without power in D.C. and Northern Virginia. Silver Spring, Maryland, was particularly hard hit, with outages claiming traffic signals.

TRAFFIC ADVISORY: Thunderstorms overnight caused major power outages, over 80 traffic lights out in Silver Spring. Rt 29 at Stewart SB, all the way to Sligo Creek Pkwy, is completely out.

Strong winds downed numerous large trees along the George Washington Parkway and Glebe Road, in north Arlington, late Saturday; the southbound lanes of both were closed for several hours. Storm water runoff from Maryland surged downstream and led to rapid water rises on Rock Creek in the District. D.C. Fire and EMS responded to a number of partially submerged drivers after 1 a.m. on Rock Creek Parkway and Beach Drive, both of which were closed between Virginia Avenue and Broad Branch Road. Montgomery County Fire and Rescue Spokesperson Pete Piringer said large trees came down in an area bordering Rockville and Potomac, with some striking occupied homes.

“Fortunately, there were no injuries,” Piringer said. “We handled about one call a minute, and most of it was in that particular area.” Fire and Rescue also had to help drivers in cars “that were stranded in a couple of feet of water,” Piringer said. “Firefighters were able to respond and assist people out of those vehicles.” Downed trees and branches Saturday evening blocked some local roads and on-ramps to Interstate 270. Though most of the severe thunderstorm threat left the area at around 9 p.m., quick bursts and lingering showers remained a hazard into the early hours of Sunday.
