UPDATE, Friday, 11 a.m. — Power outages across Alexandria fell below 2,000 by late Friday morning as Dominion Energy crews worked through the remaining storm damage, and the utility began posting restoration estimates for the first time since Thursday night's storms.
As of Dominion's 10:46 a.m. update, 1,930 Alexandria customers were without power — under a fifth of the overnight peak of 10,887 reached around 9:46 p.m. Thursday — out of about 71,210 served citywide. Outage tickets on Dominion's map listed the cause as "Storm" with crews working, and at least one cluster carried an estimated restoration window of 1 to 6 p.m. Friday. Remaining outages were scattered in pockets across the city, including the West End, near Inova Alexandria Hospital, and along the Duke Street and Eisenhower corridors.
Across Northern Virginia, outages dropped to 8,491 from nearly 55,000 at the height of the storm, with Fairfax County at 2,720. Dominion's total customers out across its service territory fell to 8,986.
The recovery is racing the day's heat. A Heat Advisory takes effect at 11 a.m. and runs until 8 p.m., with heat index values around 105 — a concern for any households still without air conditioning. The National Weather Service forecasts a high near 98, with showers and thunderstorms likely after 5 p.m., some potentially severe with damaging wind gusts or large hail. The same hazardous-weather outlook flags another round of possible severe storms Sunday.
Residents should report outages or downed power lines to Dominion Energy at 866-366-4357 or online at dominionenergy.com/outage, and report fallen trees, debris, downed traffic signals, or flooding to Alex311 at 703-746-4444. Treat any downed line as live: stay at least 30 feet away, and call 911 if a line falls on a house or vehicle.
Original Story (Published at 8:53 p.m. on June 11)
ALEXANDRIA, Va. - A fast-moving line of severe thunderstorms swept into Alexandria Thursday evening, knocking out power to roughly 9,910 Dominion Energy customers in the city and prompting a Severe Thunderstorm Warning that runs until 8:30 p.m.
The National Weather Service in Sterling issued the warning at 7:54 p.m. for the City of Alexandria and much of the surrounding region, citing a line of storms capable of 60 mph wind gusts. As of 7:53 p.m., forecasters tracked the storms moving east at 45 mph, with emergency management already reporting numerous downed trees along the line. The warning cautioned that damaging winds could topple trees and large branches, block roadways, and trigger localized power outages — a threat that has already materialized across the city.
As of the most recent Dominion Energy update at 8:46 p.m., Alexandria had 9,910 customers without power out of roughly 71,210 served — meaning close to one in seven city customers was in the dark. The outage map showed the heaviest concentrations stretched across the center of the city, with affected zones near Episcopal High School, Inova Alexandria Hospital, and along the N. Quaker Lane and Janney's Lane corridors toward Rosemont, plus pockets reaching into the West End near Landmark and Lincolnia.
Alexandria's outages are part of a much larger regional event. Dominion's Northern Virginia region reported 53,763 customers out of nearly 967,000 without power, with Fairfax County hardest hit at more than 25,000 outages. Across Dominion's full service territory, total customers out approached 55,901.
The storms arrived on an oppressively hot day. A Heat Advisory was in effect through 8 p.m. Thursday, and another is scheduled from 11 a.m. to 8 p.m. Friday, when highs near 95 and heat index values as high as 102 are forecast — a difficult combination for any households still waiting on restoration. The Weather Service warned that more showers and storms, some potentially severe, are possible again Friday afternoon and evening.
A Severe Thunderstorm Watch covers the area until 10 p.m., and a Special Marine Warning for the tidal Potomac runs until 9 p.m.
What residents should do:
- Report outages to Dominion Energy at 866-366-4357 or online at dominionenergy.com.
- Treat any intersection with a dark traffic signal as a four-way stop.
- Stay away from downed power lines and storm debris, and assume any fallen line is live.
- Move to an interior room on the lowest floor if storms intensify in your area.
This is a developing story. We'll update as conditions and restoration estimates change.
