A house in Tysons caught fire after being struck by a lightning bolt during last night’s thunderstorm, the Fairfax County Fire and Rescue Department says.

Fairfax and Arlington county firefighters were dispatched to a two-story, single-family house in the 1900 block of Hull Road at approximately 8:57 p.m. yesterday (Wednesday).

Upon arriving at the scene, the units could see fire showing through the house’s roof. They “rapidly” extinguished the fire, and there were no reported civilian or firefighter injuries, according to the FCFRD report.

However, four occupants of the house have been displaced, and the blaze resulted in approximately $90,000 in damages.

FCFRD says that the house’s four occupants were all at home when the fire started:

Four occupants were home at the time of the fire. The occupants heard a loud bang, saw a flash of lightning, and then smelled smoke. All occupants evacuated the home. 9-1-1 was called. Smoke alarms did not sound due to the location of the fire.

Fire Investigators determined that the fire was natural in nature and started on the exterior of the home. The cause of the fire was a lightning strike.

The Fairfax County and Arlington fire departments also responded to a house fire in the 7700 block of Virginia Lane in Falls Church last night. A cause and estimate of damages have not been announced yet, but the blaze did not result in any reported injuries.

More than 5,000 people in northern Fairfax County are currently without power, as a thunderstorm pummels the D.C. area.

According to Dominion Energy’s outage map, the largest outages are concentrated in the east Reston and Great Falls area and north of Tysons, where 1,075 customers between Lewinsville Road and Georgetown Pike are without power due to the storm, which started pouring rain earlier this evening (Thursday).

For the Tysons outage, a crew is currently assessing the damage, but Dominion has not determined an estimated time of restoration yet.

In a Severe Thunderstorm Warning issued at 8:21 p.m., the National Weather Service advised residents to move indoors to the lowest part of their residence.

“Large hail and damaging winds and continuous cloud to ground lightning is occurring with these storms. Move indoors immediately,” the NWS said. “Lightning is one of nature’s leading killers. Remember, if you can hear thunder, you are close enough to be struck by lightning.”

Update at 11 p.m. — Power was restored earlier tonight. The cause of the outage was an issue with a transmission line.

Earlier: The Dominion power outage map is red throughout the Tysons area — primarily east of the Beltway — as today’s storms leave thousands without power.

All of Pimmit Hills, McLean, and much of Merrifield and Falls Church have been left in the dark. The cause of the outage is still listed as “pending investigation.” The restoration time was estimated as between 5-10 p.m.
