While millions of consumers in the Washington, D.C. and 13-state region served by PJM are still recovering from Winter Storm Jonas, the high-voltage transmission grid endured no major problems and remained steady.
At the height of the storm on Saturday, however, there were 116,000 customer outages, the result of local distribution challenges. Most of those outages were in the Atlantic Electric and Delmarva Power service areas.
The hardest-hit areas in the region served by PJM:
|Glengarry, W. Va.||42 inches|
|Shepherdstown, W. Va.||40.5 inches|
|Philomont, Va.||39 inches|
|East Potomac, Md.||38.5 inches|
|Greencastle, Pa.||38.3 inches|
|Winebrenners Crossroad, W.Va.||36.4 inches|
|Round Hill, Va. (Loudon Co.)||36.3 inches|
It was the biggest snowstorm on record for Baltimore (29.2 inches), Allentown, Pa. (31.9) and Harrisburg, Pa. (34), according to the National Weather Service.
Washington saw 17.8 inches of snow at Reagan National Airport, the city’s official measurement, while suburban Washington Dulles Airport was blasted with 29.3 inches. The storm was the fourth-largest event in Philadelphia.
But snow wasn’t the only product of the storm.
Dewey Beach, Del., and Virginia’s Langley Air Force Base both reported 75 mile-per-hour winds, just over hurricane force. From Virginia to New York, sustained winds topped 30 mph and gusted to around 50 mph.
Atlantic and Cape May counties in Southern New Jersey were particularly hard hit with flooding from the back bays, resulting in flowing rivers of ice floes in the streets.
