6 p.m. OUTAGE UPDATE

Winds Prevent Immediate Restoration Efforts

Hurricane Isabel’s leading edges have hit the Washington area and have already resulted in approximately 172,000 power outages in the District of Columbia, Montgomery and Prince George’s counties in Maryland. The high winds associated with Isabel pose a danger to crew personnel and are delaying immediate restoration efforts. Once the winds diminish to a safe level, Pepco will engage in an around-the-clock effort to restore power, with crews working in 12-hour shifts.

As of 6 p.m., the following outages are reported on the Pepco system:

District of Columbia: 73,000
Montgomery County: 51,000
Prince George’s County: 48,000
Total: 172,000 customers

Those numbers are expected to rise as the storm continues to batter the area, probably well into the late evening and early morning hours.
