BROOKEVILLE, MD -- Emergency responders say they have been conducting water rescues throughout the night after a storm caused flash flooding throughout the area.

A flash flood warning was issued for much of the Washington area on Wednesday night and west of Interstate-95.

Montgomery County Assistant Fire Chief Scott Graham told WMAL.com Thursday morning that crews had to save motorists in seven different incidents overnight in the Germantown and Darnestown and Brookeville areas.

"Although the storm has passed, we still have standing water, we still have runofffrom other areas, and we're asking drivers to simply turn around -don't drown," says Graham,
 
Fire crews were kept busy in Loudoun County as well.  According to one broadcast report, a  man had to be rescued from the roof of his van in the Aldie area of Loudoun County. The driver had lost control of his vehicle and went into a ravine and was surrounded by water. He waited until Sheriff's deputies arrived to help him out. Strong winds had apparently blown down a sign declaring the road closed.

Graham says many motorists make the mistake of believing that if the rain has passed, the danger has passed as well. That is clearly not the case.
