More than 2,000 properties in Fairfax County, most of them in McLean, are currently without power, as the D.C. region suffers through a potentially prolonged heat wave.
According to its outage map, Dominion Energy has 2,132 customers in Fairfax County without power, as of 3:25 p.m. The largest outages appear to be centered around downtown McLean, where crews are assessing the damage to the affected electrical infrastructure.
The outages were caused by an equipment failure, according to a Dominion Energy spokesperson.
“Crews are working on it but customers should be back on any minute,” the spokesperson told FFXnow, clarifying that the equipment failure wasn’t heat-related.
Power could be restored sometime from 4-9 p.m., the outage map says.
The current issues in McLean don’t appear to be related to last week’s storm, which took out power for more than 70,000 properties across the county at its peak. A transformer damaged during the storm, however, has kept the popular Congressional Camp closed for two days now.
The ongoing heat wave, which is expected to be most intense early this week, has prompted the National Weather Service to issue Extreme Heat Warnings today and tomorrow (Tuesday). Forecasts have the heat index — a measurement of both temperature and humidity — reaching up to 110 degrees both days.
As of 2 p.m., temperatures in the D.C. region have hovered around the mid-90s, hitting a high of 97 degrees with a heat index of 108 in the District, the Capital Weather Gang reported.
Because of the heat, Metro is reducing the speed of its trains when they’re above ground “for safety reasons.” The transit agency limits trains to 35 mph in extreme heat, which causes the rails to expand.
“Please plan additional travel time. Stay cool out there!” Metro said in a social media post.
As a result of the heat, we are reducing speeds on above-ground track for safety reasons. Please plan additional travel time.

In addition, the Kings Park and Culmore libraries have closed for the rest of the day due to HVAC issues, Fairfax County Public Library announced this afternoon. The heat has also led Fairfax County Park Authority to cancel wagon rides at Frying Pan Farm Park in the Herndon area through tomorrow.

With a heat warning taking effect at 11 a.m., Fairfax County will activate its emergency heat plan for a second consecutive day tomorrow, encouraging community members to take advantage of cooling centers at libraries, community centers and other public facilities as needed.
“These cooling centers will also have supplies available including bottled water, sunscreen, insect repellant, and body wipes,” the county said in a news release.
As part of the heat plan, the county also works with outreach workers and other community partners to check on unsheltered residents. Suplies are also available at homeless shelters, drop-in centers, and meal distribution sites.
