Severe storms spawned two tornadoes Thursday in the District and Arlington, leaving a trail of downed trees and damage on both sides of the Potomac River.

The National Weather Service said Friday it confirmed two tornadoes touched down about 9 p.m. Both were part of a rotating storm that toppled trees along a path that began in Falls Church, then continued through Arlington, the National Mall, Southeast Washington and Capitol Heights in Maryland.

The larger of the tornadoes was an EF1 on the 0-to-5 scale for tornado damage. The Weather Service said it tracked from Arlington’s Cherrydale neighborhood to near 16th Street and Constitution Avenue NW in the District with maximum winds of 90 mph. It was as wide as 125 yards on its 4.4-mile path. The other was an EF0 tornado that touched down one mile northeast of the U.S. Capitol in the H Street Corridor and continued for 0.75 miles into the Kingman Park neighborhood. It had a maximum width of 75 yards and peak winds of 80 mph.

The storm downed trees along parts of the Mall, where crews had set up for the July Fourth fireworks celebration.

Mike Litterst, a spokesman for the National Park Service, said Friday that winds had also knocked over fencing and portable toilets. Crews worked to clean up the area before the Independence Day event Sunday, which Litterst said would continue as planned.

“It’s all hands on deck to get it cleaned up,” Litterst said. “We are confident we have resources to get it cleaned up in time” for the Fourth of July.

Pepco said fewer than 500 customers still were without power late Friday. Dominion Energy had about 3,000 customers without power, mainly in Fairfax and Arlington counties. Crews worked throughout the day to restore electricity.

Some roads remained closed Friday morning as downed trees littered the region. In Northwest Washington, Canal Road was closed at Foxhall Road because of a downed tree. And high water forced the closure of Nannie Helen Burroughs and Minnesota avenues in Northeast Washington during the morning hours.

Metro suspended service for much of the day Friday on part of the Orange Line — between the West Falls Church and Vienna stations — because of a power outage at the Dunn Loring station. A Metro spokesman said flooding damaged the electrical system at the station. Service was restored about 4 p.m.

In Takoma Park, Montgomery County Fire Department spokesman Pete Piringer said a large tree fell and power lines were downed near Sherman and Maple avenues. He said several houses were evacuated but no one was injured.

One person became trapped Thursday evening inside a house in the 4300 block of 16th Street North in Arlington after a tree struck the home, said Lt. Nate Heiner, an Arlington County Fire Department spokesman. Medics took the person to a hospital with injuries that weren’t life-threatening.

Prince George’s County fire officials said a large tree fell through the roof and into a bedroom of an unoccupied home in Bowie.

Temperatures climbed into the low 80s across much of the Washington region Friday, with similar conditions expected this weekend before climbing early next week.
