SURVEY SUMMARY: A TORNADO TOUCHED DOWN ON THE WEST SIDE OF MEMORIAL
PARKWAY IN THE 9000 BLOCK OF CRAIGMONT DRIVE. IN THIS AREA...SEVERAL
LARGE TREES WERE SNAPPED OR UPROOTED WITH AT LEAST ONE FALLING ON THE
BACK OF A HOUSE. THE TORNADO MOVED NORTHEAST CROSSING THE PARKWAY
WITH TREES SNAPPED ALONG OLDFIELD ROAD. EXTENSIVE POWER LINE AND
POWER POLE DAMAGE WAS NOTED AT THE INTERSECTION OF WHITESBURG DRIVE
AND LILLY FLAG ROAD. SEVERAL WOODEN POLES WERE SNAPPED NEAR THE BASE
AND A STREET LIGHT WAS SNAPPED AT THE BASE AS WELL. SEVERAL BUSINESS
SIGNS WERE BLOWN OUT IN THE AREA. THE TORNADO WAS LIKELY AT ITS
STRONGEST POINT IN THIS AREA REACHING EF-1 INTENSITY.

THE TORNADO THEN MOVED ACROSS SEVERAL RESIDENTIAL NEIGHBORHOODS
SNAPPING AND UPROOTING BOTH SOFT AND HARDWOOD TREES. MINOR DAMAGE TO
ROOFS...MAINLY FROM FALLING TREES...WAS ALSO NOTED. A LARGE TREE FELL
ON A HOUSE ON VALLEY VIEW DRIVE CAUSING MAJOR DAMAGER TO THE HOME.
THE OCCUPANTS RELAYED THAT THEY HEARD THE SIRENS AND TOOK COVER
SEVERAL MINUTES BEFORE THE TREE FELL THROUGH THE DINING ROOM.

THE TORNADO CROSSED HICKORY HILL ROAD SNAPPING TREES AND EVENTUALLY
CAUSING MINOR TREE DAMAGE IN THE VALLEY HILL COUNTRY CLUB AREA. THE
TORNADO FINALLY LIFTED NEAR HAVEN STREET JUST WEST OF BAILEY COVE
