UPDATE: Storm dropped up to 6 inches on Richmond

Richmond-area authorities reported little damage from an overnight thunderstorm that brought some much-needed rain to the region.

The heaviest rain the Richmond area has seen this summer _ up to 6 inches in some parts of the capital area, according to the National Weather Service _ left more than 6,000 Dominion Virginia Power customers without electricity in the region at one point. But that figure had decreased to slightly more than 300 by 10 a.m.

In Richmond, authorities reported some street flooding at the usual spots, including several cars that were stranded in high water along Midlothian Turnpike. In addition, several manhole covers were dislodged by rushing water, and a street sweeper was called to the East End to brush away several inches of mud near the intersection of Williamsburg Road and East Main Street.

Authorities in Chesterfield and Henrico counties reported minimal damage beyond a few downed trees, and Hanover County officials said their biggest problem was some high water at Lee Davis and Pole Green roads.

Brian Hurley, a meteorologist with the weather service's Wakefield office, said radar estimates show many parts of the Richmond area got 3-5 inches of rain, with some isolated areas getting as many as 6 inches from the storm that moved through about 3 a.m.

"It was just a slow-moving boundary," he said. "Anything this time of year tends to be slow-moving. August is the peak month for slow-moving boundaries."
