Most power outages cleared after storm

WASHINGTON – Heavy winds and rain whipped through the region Tuesday afternoon, downing trees and causing outages throughout the WTOP listening area.

Flash flood and tornado warnings were also issued by the National Weather Service, but were later canceled.

At its peak, tens of thousands were without power, but by early Wednesday only about 600 Potomac Edison customers were still in the dark, mostly in Frederick County, Md. Other power companies have restored their outages.

In Arlington, the wind sent a tree crashing into a home. No one was hurt.

Because of the pounding rain, the Washington Nationals canceled Tuesday’s game against the Dodgers. It is being rescheduled for Wednesday afternoon.

In Maryland, a downed tree interrupted service on the MARC train. The tracks were then cleared on the Brunswick Line. On the Penn Line, MARC canceled train 403 at 5 a.m.

Amtrak says service between Washington and Baltimore continued to be delayed because of signal problems. Repairs are being done.
