TORNADO...DEBRIS REPORTEDLY WAS LOFTED AND CIRCULATED BENEATH A 
PENDANT FUNNEL UNTIL IT DISSIPATED. THE PATH WAS DETERMINED BY 
TRIANGULATION FROM MULTIPLE VANTAGE POINTS AND RADAR DATA. THE 
TORNADO WAS LOCATED IN REMOTE WOODED PORTIONS OF QUANTICO MARINE

HONOR GOLF COURSE. BASED UPON THIS DAMAGE...A RATING OF EF-0 IS 
ASSIGNED...WITH MAXIMUM WIND SPEED OF 65 MPH. HOWEVER...A PATH WIDTH 
AND TRUE MAXIMUM WIND SPEED ARE INDETERMINATE OWING TO AN INCOMPLETE 
PATH SURVEY THROUGH INACCESSIBLE WOODED AREAS.
