High Winds Blow Off Part of Roof; Down Trees, Power Lines

Storm Team4 has declared Monday a Weather Alert day

High winds blew off part of an apartment building's roof and downed trees and power lines around the Washington region.

D.C. Fire and EMS officials tweeted early Monday that the roof blew off part of a three-story apartment building in southeast Washington, but no one was hurt. The Red Cross was called in to help residents. 

The National Weather Service tweeted a 66 mph wind gust was measured at Reagan National Airport late Sunday. A gust of 73 mph was reported at Joint Base Andrews Monday morning. 

Downed power lines and trees closed roads and caused outages. At its peak, Dominion Power reported about 13,000 customers without power in Virginia, mostly in northern Virginia. Outages prompted Fairfax County Public Schools to open two hours late. 

In Montgomery County, Maryland, multiple trees have fallen and at least two fell onto houses.

Maryland officials reported about 17,000 outages overnight, but about 5,000 remained by dawn.

A high wind warning was in effect Monday, but the warning was canceled after noon. A wind advisory remains in effect until 6 p.m., with 20 to 30 mph winds and gusts up to 50 mph. 

It's been a sunny and cold day, with highs in the 40s, but wind chills in the 20s and 30s.

Wires downed by strong winds on South Quinn St. and Columbia Pike in Arlington, Virginia, sparked an electrical fire, police and fire officials confirmed to News4.

In Montgomery County, Maryland, multiple trees have fallen and at least two fell onto houses, said Montgomery County Fire and Rescue spokesman Pete Piringer. No injuries have been reported.
