More than 3,000 people lost power across the region during a severe thunderstorm that rolled through the area Thursday afternoon.

According to Pepco’s web site, as of 6:45 p.m., 3,704 customers in Prince George’s County were without power, while 12 customers were without electricity in Montgomery County. At the same time, Baltimore Gas and Electric reported 10 outages in Prince George’s.

Bob Hainey, a Pepco spokesman, described the storm as a “pop-up storm,” which caused damage to trees and downed wires primarily along Crain Highway in the Rosaryville area. At least 30 repair crews were heading into the area, Hainey said, and most people would be without power for between five and six hours.

“A smaller group of people will likely be out for a few hours longer,” Hainey said. “And another group might get power back pretty quickly. But the bulk of the outages are about a five-hour job.”

Prince George’s police and fire/EMS departments said there were no notable incidents as a result of the storm.

Mark Brady, a county fire/EMS spokesman, said there have been reports of one or two minor motor vehicle accidents, but nothing serious. He advised residents to avoid the storm conditions by staying indoors.

“If at all possible, stay indoors. As storms roll through, it’s going to provide lot of rain, possible hail, wind and lightening,” he said.
