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.”

Heavy rains and damage came after a storm blasted through Tysons on Thursday (via @RealPotatus)

Fairfax County was, in fact, hit by two tornados during last week’s rainstorm.

The National Weather Service determined there was a tornado in Centreville on Thursday (March 31), in addition to the one that touched down in Tysons.

The tornado had peak winds of 85 miles per hour, according to NWS, which conducted a damage survey today (Monday).

Approximately 15 pine trees were snapped or uprooted at the end of Batavia Drive behind Cub Run Elementary School.

“No damage to nearby residences or other structures was evident during the survey,” the report reads. “The tornado was on the ground for well under a minute.”

The NWS estimates the tornado tore an about 80-yard path with a width of 30 feet around 8:21 p.m.

The Tysons hurricane didn’t touch down until about 20 minutes later and was also rated as an EF0 but damaged two gas stations.

…NWS Damage Survey for 03/31/22 Tornado in Centreville VA…

Rating: EF-0

Path Length: 80 yards
Path Width /maximum/: 30 yards
Fatalities: 0
Injuries: 0

Start Date: March 31, 2022

End Date: March 31, 2022
End Time: 8:22 PM EDT
End Location: Centreville VA
End Lat/Lon: 38.8655/-77.4570

Narrative:

Today, the National Weather Service in Sterling, Virginia, conducted a survey of storm damage in Centreville, Virgina, of localized damage from storms that occurred Thursday evening, March 31, 2022.

It was determined that a brief tornado occurred in Centreville, Virginia, near the end of Batavia Drive behind Cub Run Elementary School. Multiple softwood pine trees surrounding the end of Batavia Drive were impacted/damaged by the tornado, with several snapped and others uprooted. No damage to nearby residences or other structures was evident during the survey. The tornado was on the ground for well under a minute.

The tornado touched down immediately east of Cub Run Elementary School and transited from west to east toward the cul-de-sac at the end of Batavia Drive. The cul-de-sac was formerly surrounded by about two dozen trees. The seven trees on the south side of the cul-de-sac were undamaged, while most of the remainder were either uprooted, snapped at the base, or snapped 10-15 feet in the air. One of the tree tops was turned in mid-air and landed
opposite to its expected orientation had this been straight-line winds, indicative of a very brief tornado touchdown.

The tornado lifted as it moved east of the cul-de-sac.

Weather radars from NOAA/NWS KLWX WSR-88D in Sterling, VA, and FAA Terminal Doppler Weather Radars for Reagan National Airport, and Joint Base Andrews, all had corroborating doppler radar velocity data supporting the tornadogenesis.

EF Scale: The Enhanced Fujita Scale classifies tornadoes into the following categories:

EF0………65 to 85 mph
EF1………86 to 110 mph
EF2………111 to 135 mph
EF3………136 to 165 mph
EF4………166 to 200 mph
EF5………>200 mph

Tysons Sunoco and Mobil gas stations were damaged by a storm Thursday night (staff photo by David Taube)

(updated at 4:20 p.m.) The National Weather Service determined a tornado touched down in Tysons last night (Thursday).

NWS confirmed what some suspected after onlookers posted videos to social media showing what looked like a funnel.

The tornado, which was the lowest category with winds between 65 to 85 mph, caused damage to two gas stations along Chain Bridge Road. NWS reported the winds lifted upward under the canopy of the Sunoco and caused a corner of it to collapse on the station’s building.

Rating: EF-0
Estimated Peak Wind: 85 mph
Path Length: 200 yards
Path Width /maximum/: 50 yards
Fatalities: 0
Injuries: 0

At the Mobil not too far away, the garage door “was blown 10 to 15 feet away from the building.”

The Capital Weather Gang had reported there may have also been a brief tornado touchdown near Centreville based on preliminary information. But National Weather Service meteorologist Ray Martin told FFXnow this afternoon (Friday) that the agency hadn’t heard of much damage in that area to indicate a tornado or prompt a survey.

…NWS Damage Survey for 03/31/22 Tornado in Tysons Corner VA…

Rating: EF-0
Estimated Peak Wind: 85 mph
Path Length: 200 yards
Path Width /maximum/: 50 yards
Fatalities: 0
Injuries: 0

Start Date: March 31, 2022
Start Time: 8:41 PM EDT
Start Location: Tysons Corner VA
Start Lat/Lon: 38.9196/-77.2259

End Date: March 31, 2022
End Time: 8:42 PM EDT
End Location: Tysons Corner VA
End Lat/Lon: 38.9195/-77.2234

Narrative:

A tornado touched down in Tysons Corner, Virginia, along Chain Bridge Road just northwest of the Tysons Corner Mall. Two service stations were impacted/damaged by the tornado. The first one, a Sunoco gas station situated at the corner of Chain Bridge Road and International Drive, had a partial canopy collapse. Winds lifted upwards under the canopy and caused the northwest corner of the canopy to collapse on the service station building.

A group of bushes separating the two service stations experienced significant vegetation loss on the southeast facing side. The Mobil gas station separated approximately 120 feet from the Sunoco gas station experienced a number of impacts to the building and surrounding objects. A garage door facing northwest was blown 10 to 15 feet away from the building. Metal paneling at the top of the roof along the northwest and southeast facing sides of the building were damaged and tossed away from the building. A small canopy hanging over the entrance of the service station was mangled beyond repair. A video posted on social media displayed a number of loose items, including packs of water and other small items tossed around in a rotating fashion in the front of the building. Flying debris also caused at least 6-8 windows in the front of the Mobil station to shatter.

Eyewitness accounts along with a social media report show the tornado as it just passed the Mobil gas station and was approximately 100 yards away with clear rotation in the video as it approached just northwest of Tysons Corner Mall just off of Tysons One Place. Based off of lack of damage displayed further southeast, the tornado likely dissipated in the Tyson’s Corner Mall parking lot.

Finally, weather radars from NOAA/NWS KLWX WSR-88D in Sterling, VA, and FAA Terminal Doppler Weather Radars for Dulles International Airport, Reagan National Airport, and Joint Base Andrews, all had corroborating velocity data supporting the tornadogenesis.

EF Scale: The Enhanced Fujita Scale classifies tornadoes into the following categories:

EF0………65 to 85 mph
EF1………86 to 110 mph
EF2………111 to 135 mph
EF3………136 to 165 mph
EF4………166 to 200 mph
EF5………>200 mph
