Yuh oh, looks like some folks won't have power when they get home. PEPCO's online map shows a power outage at about Girard and Sherman and another at roughly Spring and Georgia. (If you click "locations" instead of "areas" you see the actual spots.)
DDOT's Twitter also says traffic signals are out on 11th and Sherman.
Hope your place isn't one of them!
UPDATE: DDOT's Twitter says the signals are back on, but not sure if that also means the houses are back on.
