Updated at 4:25 p.m. — A Severe Thunderstorm Warning has now been issued for Fairfax County. In effect until 5 p.m., storms are moving east at 15 miles per hour with 60 mile-per-hour wind gusts that could bring down trees and large branches, potentially leading to power outages.

Earlier: While the Reston area largely got through last night’s thunderstorm unscathed, Fairfax County is already bracing for another potentially damaging storm.

The National Weather Service has put the entire D.C. region under a Severe Thunderstorm Watch until 9 p.m., warning of the potential for hail and damaging winds similar to the blasts that disrupted travel and power in the Vienna and Falls Church area yesterday (Tuesday).

Like much of the D.C. area, Fairfax County is now under a Severe Thunderstorm Watch that will be in place until 9 p.m.

The region is bracing for a second consecutive night of potentially damaging wind and rainfall after a storm that swept through late Wednesday (July 28) resulted in power outages that affected thousands of people in Fairfax County, particularly around McLean and Falls Church.

While many of the outages have been addressed, Dominion Energy’s outage map shows that, as of 3:30 p.m., crews are still working to restore electricity in some areas.

A Tornado Watch has been issued for D.C.’s Maryland suburbs, but Fairfax County could see damaging hail, isolated flash flooding, and large hail from the incoming storm, according to the National Weather Service.

The Fairfax County Office of Emergency Management advises residents to “stay weather aware and know what to do if a warning is issued,” which would mean that severe weather is imminent or underway.
