Storms continued into the final hours of Friday in the Washington area, producing one of the wettest days of the year and knocking out power to thousands of homes and businesses.

At about 10:30 p.m., about 25,000 utility customers in areas that included Northern Virginia and Southern Maryland were without electricity, power companies said.

As midnight approached, 0.95 inches of rain had been reported at Reagan National Airport. Heavy rain continued to fall, suggesting that the day’s total could go as high as an inch.

Preliminary figures indicated that by 11 p.m., significantly more than an inch of rain had been measured at Dulles International Airport.

In Prince George’s County, fire department spokesman Mark Brady said houses and trees were damaged by the storm on at least two streets in the Upper Marlboro area: the 5000 block of Ashford Drive and the 11000 block of Buggy Path Road.

“Quite a dousing,” a commenter in western Fairfax County told The Washington Post’s Capital Weather Gang site.

Saturday and Sunday were expected to be cooler and drier, continuing a series of pleasant weekends here, the National Weather Service said.
