Potomac Edison says it crews and contractors continue to work to bring all of its customers who lost electricity back on line. Spokesman Scott Surgeoner says the company hopes to have most if not all customers in Maryland restored  by late Tuesday or early Wednesday.

"Friday evening, we've seen wind gusts that were recorded throughout the state and back into to West Virginia of 60, 70 miles an hour and above," says Surgeoner. "So the storm was significant, and the winds were significant. Trees coming down on our facilities. Trees and our facilities never mix."

"We are recovering from a hurricane punch without the typical hurricane warning," says Maryland Governor Martin O'Malley, speaking on a YouTube video from the state's emergency operations center  He has been pressuring utilities to move as quickly as possible to restore power, and try and do better than their promises of having the "juice" back on by Friday.

Potomac Edison has brought in crews from other 1st Energy utilities, as well as contractors, some from as far away as Florida, according to Surgeoner. 1st Energy is Potomac Edison's parent company.

Potomac Edison says at the height of the storms, 63,000 customers were out of power. That number has been brought down to about 2300 in Frederick County as of Monday morning.

While some people without power  may not have seen a Potomac Edison truck in their neighborhoods, that doesn't mean they're not working, says Surgeoner. "What we focus on, primarily, in the beginning of an outage restoration process, is the larger transmission lines, those lines that carry large amounts of electricity for us from a generator plant somewhere to our substations. And then we go work from the substation out," he says. Right now, Surgeoner says all of the transmission lines and substations are repaired, and crews will begin working in the communities.

Each crew member works 16-hour shifts during a 24-hour period, with eight hours for rest during an outage like this.

The powerful weather event, known as a derecho, a straight line of storms with strong winds, brought a lot of destruction through parts of the Midwest into the Mid-Atlantic states.

18 deaths have been so far been reported as a result of the storms.
