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
