More homes and businesses in the D.C. area had power restored overnight, but about 200,000 local Pepco and Dominion Power customers are still in the dark.

Nearly 117,000 Pepco customers in the District, Montgomery County and Prince George's County were without power as of 8 a.m. today.

The company has restored power to about 75 percent of customers, Pepco spokesman Clay Anderson said. Of the 443,000 customers who lost power from the storm, about 326,000 have had power restored, Anderson said.

Pepco Region President Tom Graham said on WTOP this morning that Pepco hopes to restore power to at least 90 percent of customers by 11 p.m. Friday.

"I wish that could be better," he said.

As of 9:04 a.m. today, Dominion reported that 86,777 customers in Northern Virginia were without power. Dominion reported that 540,000 local customers were without power on Friday.

Dominion's goal is to have power restored to about 90 to 95 percent of customers by Thursday night and practically all customers by Saturday night.

The D.C. area could see thunderstorms today and Wednesday, which could delay efforts to bring power back.

According to the National Weather Service, showers and thunderstorms could occur today after 2 p.m. as well as overnight, with a 20-percent chance of precipitation. For Independence Day, forecasters say showers and thunderstorms are also possible, with a 40-percent chance of rain. There's also a slight chance of storms Wednesday into Thursday.

Anderson said Pepco crews normally work in inclement weather and would only stop work in the event of severe weather. A Dominion spokesman also said the company is keeping an eye on the weather and crews will continue to work unless storms threaten.
