WASHINGTON (AP) - Tens of thousands are without power in Maryland, Delaware and neighboring states after a series of morning thunderstorms, which left trees down and roads closed. And part of the mid-Atlantic region, including Washington, D.C., is bracing for an even more severe pounding later on today.
It's part of a massive storm system that brought widespread power outages and flash flooding along its path from the upper Midwest.
Forecasters in the Washington area warn that the storms could bring damaging winds and large hail. They say the threat will run until early this evening. The area is under a flash flood watch. The federal government today allowed workers to take unscheduled leave or to work from home.
A flash flood watch for the entire state of Pennsylvania is in effect through tonight. This morning, commuters tried to get to work amid torrential downpours and dark skies that made it look like nighttime. Play was suspended at the U.S. Open golf tournament outside Philadelphia for about three hours.
