UPDATED (2:19 p.m.)—Gov. Martin O'Malley said state officials are assessing damage across Maryland in the wake of a severe line of thunderstorms that has knocked out power to more than 820,000 customers statewide.
In a conference call with reporters, the governor and other state officials said they are assessing the need for cooling centers as the state faces expected severe hot weather over the next several days.
Power restoration is also a priority as emergency management officials say they are tracking a line of severe storms that are expected to hit the state as early as late Saturday afternoon.
