Tropical Storm Ophelia is expected to bring rain and wind to Northern Virginia this weekend (via National Weather Service)

Updated at 4:05 p.m. — A Coastal Flood Advisory issued for parts of Northern Virginia, including Fairfax County, will now take effect at midnight, earlier than initially anticipated, the National Weather Service says.

Earlier: It’s going to be a cold and rainy weekend in Fairfax County, thanks to Tropical Storm Ophelia.

Tracking to make landfall in North Carolina today (Friday), the storm is expected to reach Northern Virginia tonight with “heavy rain, high winds, and cool temperatures” continuing into Sunday (Sept. 24) morning, according to the Fairfax County Department of Emergency Management.

“Locally, [the National Weather Service] expects 2-4 inches of rain throughout the weekend,” the county said in a post on its emergency information blog. “Since the precipitation will be spread across the weekend, flooding is not a major concern but could cause some localized flooding issues. Wind speeds will gradually increase, peaking around 40 mph on Saturday.”

The storm has already affected some major events, prompting cancellations of the popular Reston Multicultural Festival, the inaugural Fairfax Fiesta in Tysons and a kick-off for National Public Lands Day in Annandale. Other events, like Fairfax City’s Fiesta Fairfax, have been relocated indoors.

The NWS has issued a Coastal Flood Advisory and a Wind Advisory for much of the D.C. area, including Fairfax County.

The flood advisory will be in effect from noon tomorrow (Saturday) to 5 a.m. Sunday:

* WHAT…Up to one half foot of inundation above ground level expected in low lying areas due to tidal flooding.

* WHERE…Fairfax, Stafford and Central and Southeast Prince William/Manassas/Manassas Park Counties.

* WHEN…From noon Saturday to 5 AM EDT Sunday, especially around the time of high tide.

* IMPACTS…Flooding of lots, parks, and roads with only isolated road closures expected.

* ADDITIONAL DETAILS…Tides one and a half to two feet above normal. The worst flooding will occur with the Saturday afternoon and Saturday night high tides.

The Wind Advisory will take effect at 8 a.m. tomorrow and last until 8 p.m., warning that northeast winds could reach 20 to 30 mph with up to 45-mph gusts. The NWS notes that the “gusty winds” could blow around objects and result in power outages. Read More

Power outages in Fairfax area on Aug. 8, 2023 (via Dominion Energy)

Utility crews are still working to restore electricity to over 2,000 customers after last night’s storms.

As of 9 a.m., there were 2,545 people in the county without power, according to PowerOutage.US, which collects data from utilities across the country. That includes 1,672 Dominion Energy customers and 873 customers of the Northern Virginia Electric Cooperative (NOVEC).

The scope of the outages has been reduced significantly overnight after strong winds and rain knocked out power for more than 16,000 people by 7 p.m. yesterday (Monday). The county was hit hardest south of I-66, particularly around Fairfax City and Annandale.

According to its outage map, Dominion Energy is estimating that power will be restored to the still-affected areas around 3-8 p.m. today. Spokesperson Peggy Fox reported around 8:30 a.m. that the company has 6,000 remaining outages at 240 different locations across the region.

There is at least one lingering road closure. Henderson Road near Seven Hills Lane in Clifton is still blocked by a downed tree, the Fairfax County Police Department tweeted, advising drivers to find alternate routes.

Last night, the department said debris and downed wires had closed “several secondary roads,” but no major ones, resulting in limited traffic impacts.

Overall, last night’s storms caused less damage than forecasters had feared. Warnings of potential tornadoes prompted facility closures and an early end to the work day for many, including local federal government employees.

(Updated at 8:05 p.m.) Thousands of people in Fairfax County have been hit by power outages in the wake of a thunderstorm that’s continuing to march eastward toward D.C.

As of 7:15 p.m., there were 16,029 customers in Fairfax County and another 1,770 customers in Fairfax City without power, according to Dominion Energy’s outage map, which shows 90 separate outages.

The most sizable outages appear to be focused south of I-66, with thousands affected around Fairfax City, including around George Mason University’s campus, and Fairfax Station. Major outages also appear in Great Falls, Annandale and Lincolnia.

The outages may have affected the Burke Centre Library and the John Marshall Library in Rose Hill. Fairfax County Public Library says both branches were closed at 6:45 p.m. “due to facilities issues.”

While there have been no reports of hail or tornadoes yet, the storm has kept the Fairfax County Fire and Rescue Department busy with calls for downed wires and trees.

The department reported at 5:54 p.m. that it had units working 12 different calls for outside fires.

Road closures have also cropped up, according to the Fairfax County Police Department. A spokesperson says no major roads have been shut down, but “there are several secondary roads that may have debris or downed wires.”

“Due to inclement weather, multiple roads in Fairfax County are closed or blocked. #FCPD will respond and provide updates as soon as possible,” the department said on Twitter.

Metro, which has activated its Emergency Operations Center, is delaying trains and buses in some areas due to the weather.

Updated at 5:35 p.m. — The storm has been deemed “destructive” for Clifton, Burke and Annandale, with the National Weather Service warning of “considerable damage to trees and power lines” and that “your life is at significant risk if outdoors.”

Earlier: A storm bringing intense winds and potentially even hail or a tornado is bearing down on the D.C. area.

In anticipation of the weather, the Fairfax County Park Authority closed several outdoor facilities at 4 p.m., including the Water Mine Family Swimmin’ Hole at Lake Fairfax Park in Reston, the Martin Luther King Jr. Pool in Gum Springs and Our Special Harbor Spray Park in Groveton.

All golf courses and driving ranges, marinas and park amusements, like carousels, have also been shut down. Outdoor classes and activities have either been canceled or moved indoors.

With the line of storms moving eastward, the northwestern part of the county is expected to get hit first. The National Weather Service has issued a Severe Thunderstorm Warning until 5:15 p.m. for that area, including Reston, Herndon and possibly Tysons.

The alert warns of 60 mph wind gusts and quarter-sized hail.

“Damaging winds will cause some trees and large branches to fall,” the NWS said. “This could injure those outdoors, as well as damage homes and vehicles. Roadways may become blocked by downed trees. Localized power outages are possible. Unsecured light objects may become projectiles.”

The storm is expected to arrive during the afternoon rush-hour around 5-7 p.m., prompting local federal government offices and other many workplaces to send employees home early.

Metro is “deploying additional resources to respond to weather-related issues” that may affect its service, activating its Emergency Operations Center.

“Severe delays, disruptions, and detours in Metro bus, rail, and paratransit service are possible due to extremely high winds, road conditions and other hazards,” Metro said in a news release.

Some more stormy weather could wash over the D.C. area later today.

A Tornado Watch has been issued for the region, including Fairfax County, by the National Weather Service, which has also designated most of the area as at “Moderate Risk” of severe thunderstorms this afternoon and evening.

This is the first time in a decade that the agency has placed the D.C. area under that level of risk for hazardous weather, according to the Capital Weather Gang.

“Widespread damaging wind gusts are likely, with potential for locally destructive winds,” the NWS said. “Tornadoes and large hail are also possible. Have a way to receive warnings!”

The Tornado Watch will be in effect until 9 p.m.

The storms are expected to move eastward, reaching Fairfax County during the afternoon rush-hour, according to the county’s emergency information blog.

Wind gusts of up to 80 mph are possible in central and western Virginia, with most eastern areas facing possible gusts closer to 60-70 mph, the Virginia Department of Transportation said in a news release. The department also warned of localized flooding, large hail and “brief spin-up tornadoes.”

“The safety of the traveling public and our crews is VDOT’s top priority,” VDOT said. “As forecasts and conditions could change, travelers should pay close attention to local weather reports and announcements from officials and limit their travels based on conditions.”

Most of the GW Parkway’s northern section is closed as crews continue to remove trees knocked down by Saturday’s storm (via Google Maps)

(Updated at 1:35 p.m.) The ear-splitting thunder that accompanied Saturday’s rainstorm has faded, but efforts to clean up the resulting damage continue.

All southbound lanes on the northern section of the George Washington Memorial Parkway in McLean and Arlington remained closed during rush hour this morning (Monday), as crews worked to remove fallen trees.

“Currently, the northern section (from Spout Run Parkway to I-495) continues to be closed, with the exception of the northbound lanes from Route 123 to I-495,” the National Park Service said last night, urging drivers “to use caution in the area.”

The cleanup effort is expected to take another three to four days, according to the park service, which has deployed five different teams to assist.

“These closures are necessary to ensure the removal of hazardous trees, including those that have fallen across the roadway and broken limbs that pose a risk to travel lanes,” the NPS said in an update shortly before 1:30 p.m.

According to Dominion Energy, 768 of its customers in Fairfax County are still without power, as of 9:30 a.m.

The largest outage is in the West Falls Church area along Sleepy Hollow Road, affecting 437 people. The estimated time of restoration is still undetermined “pending investigation,” according to the utility company’s outage map.

There are also still smaller outages scattered around the Seven Corners area, Springfield and the Richmond Highway corridor.

Over the past couple of days, Dominion has managed to restore power to most of the 128,000 customers in Virginia who experienced an outage during the storm on Saturday (July 29), including approximately 26,000 people in Fairfax County.

“This was a severe storm with winds as high as 60-80 mph, which caused significant damage to trees, branches and power lines,” Dominion said in a tweet yesterday, stating that its crews would continue working through the evening to restore electricity for all those still affected.

The Fairfax County Fire and Rescue Department said it responded to 238 calls between 4:30 p.m. and 10 p.m. on Saturday — double the call volume it sees on a typical summer Saturday.
