WASHINGTON, D.C. – Pepco is closely monitoring approaching winter thunderstorms. The National Weather Service has issued a Wind Advisory for the Washington Metropolitan Area until 6 a.m. Thursday. The strongest winds are expected late this afternoon and this evening out of the south at 25 to 35 mph with gusts up to 45 to 50 mph.
High winds can bring tree limbs into contact with power lines causing power outages. Heavy rain can adversely affect saturated soil and allow trees already weakened by previous storms to fall onto power lines and equipment to cause power outages. Outages can also occur due to drivers skidding into utility poles along wet roads.
Pepco will have extra line and tree crews available and the Call Center will be staffed overnight. Pepco has about 150 internal linemen and more than 400 contractors already working on its system available if needed.
Customers are asked to please call in any outages and stay away from any down wires. ? To report outages and/or downed wires, please call 1-877-PEPCO-62 (1-877-737-2662), follow the prompts, and please ask for a call back to confirm that power has been restored.
