07/29/2021                   PHILADELPHIA       PA   NWS STORM SURVEY 

            A BRIEF TORNADO OCCURRED IN THE BUSTLETON 
            SECTION OF NORTHEAST PHILADELPHIA. DAMAGE 
            WAS FIRST OBSERVED NEAR GRANT AVE AT THE 
            GRANT GARDENS APARTMENT COMPLEX, WHERE SOME 
            MINOR LOSS OF ROOFING MATERIAL WAS NOTED AND 
            DEBRIS WAS TOSSED IN A CHAOTIC MANNER 
            CONSISTENT WITH TORNADIC WINDS. THE TORNADO 
            MOVED EAST-SOUTHEAST ACROSS ROOSEVELT BLVD. 
            CONTINUED MINOR STRUCTURAL DAMAGE WAS NOTED 
            ALONG A NARROW PATH, MAINLY CONSISTING OF 
            SPORADIC LOSSES OF SIDING AND INSULATION. 
            MINOR TREE DAMAGE WAS ALSO NOTED. ONE 
            BUILDING ALSO HAD CEILING TILES PULLED 
            DOWNWARD WITH INSULATION REMOVED IN A CAR 
            PARK AREA, A STRONG INDICATOR OF TORNADIC 
            PRESSURE GRADIENT FORCES. NEAR BLUE GLASS 
            RD, A COUPLE OF SLIGHTLY LARGER TREES HAD 
            THEIR TRUNKS SNAPPED, AND WINDS OF AROUND 80 
            MPH LIKELY OCCURRED IN THAT AREA. THE DAMAGE 
            PATH ENDED NEAR THERE, HOWEVER, AFTER A 
            TRACK LENGTH OF ONLY AROUND HALF A MILE. 
            RADAR DATA INDICATES THIS WAS AN 
            ANTICYCLONIC TORNADO. THE NATIONAL WEATHER 
            SERVICE WOULD LIKE TO THANK THE PHILADELPHIA 
            OFFICE OF EMERGENCY MANAGEMENT FOR THEIR 
            ASSISTANCE IN COMPLETING THIS SURVEY.
