THE SOMERTON-TREVOSE-BENSALEM TORNADO BEGAN IN SOMERTON IN 
PHILADELPHIA COUNTY NEAR SOUTHAMPTON ROAD, KELVIN AVENUE, AND 
TREVOSE ROAD WHERE IT UPROOTED AND BLEW DOWN LARGE LIMBS FROM A 
FEW SOFTWOOD AND HARDWOOD TREES. THE TORNADO CROSSED COUNTY LINE 
ROAD INTO TREVOSE IN BUCKS COUNTY WHERE A LARGE TREE WAS UPROOTED.
THE TORNADO CONTINUED BETWEEN TREVOSE ROAD AND PEYTON STREET 
WHERE ADDITIONAL TREE DAMAGE OCCURRED BEFORE CROSSING LUKENS 
STREET. THE TORNADO THEN VERY BRIEFLY CROSSED BACK INTO 
PHILADELPHIA COUNTY AT THE NORTHERN TIP OF POQUESSING VALLEY PARK 
WHERE A FEW TREES WERE UPROOTED. THE TORNADO THEN CROSSED BACK 
INTO TREVOSE IN BUCKS COUNTY WHERE IT CAUSED SOME MINOR COSMETIC 
DAMAGE TO SOME HOMES IN THE BEECHWOOD ESTATES NEIGHBORHOOD AND 
BLEW DOWN SEVERAL SECTIONS OF VINYL FENCING. SEVERAL SMALL TREES 
WERE ALSO SNAPPED OR UPROOTED IN AND JUST SOUTH AND EAST OF THE 
RESIDENTIAL NEIGHBORHOOD.

AS THE TORNADO APPROACHED SOMERTON ROAD, IT BEGAN INTENSIFYING 
AND WIDENING SUBSTANTIALLY AS IT MOVED INTO THE METROPOLITAN 
INDUSTRIAL CENTER. NUMEROUS SOFTWOOD AND HARDWOOD TREES WERE 
SNAPPED OR UPROOTED IN THE SUEZ WATER COMPANY PROPERTY SOUTHWEST 
OF AND ALONG SOMERTON ROAD. FIVE WOODEN POWER POLES WERE SNAPPED 
NEAR THE GROUND ALONG SOMERTON ROAD AS WELL AT THE NORTHERN END OF
THE SUEZ PROPERTY. ALL SEVEN WAREHOUSE BUILDINGS IN THE 
INDUSTRIAL COMPLEX NORTHEAST OF SOMERTON ROAD SUSTAINED AT LEAST 
MINOR DAMAGE, WITH THE MOST SIGNIFICANT OCCURRING TO THE NORTHTEC 
BUILDING. NUMEROUS ROOF MOUNTED HVAC UNITS WERE SHIFTED OR BLOWN 
OFF OF A FEW OF THE BUILDINGS IN THE INDUSTRIAL COMPLEX. OPEN BAY 
DOORS IN THE WESTERN- MOST BUILDING CAUSED A NON-LOAD BEARING 
INTERIOR WALL TO COLLAPSE. A SEDAN WAS LIFTED AND FLIPPED OVER IN 
THE NORTHTEC PARKING LOT AND A STEEL FLAG POLE BEARING A FLAG 
FLATTENED COMPLETELY TO THE GROUND. THE NORTHTEC BUILDING 
SUSTAINED SUBSTANTIAL STRUCTURAL DAMAGE WHERE LARGE SECTIONS OF 
ROOFING MATERIAL WERE REMOVED. ADDITIONALLY, NUMEROUS EXTERIOR 
PANELING WAS BLOWN OFF, GARAGE BAY DOORS WERE BLOWN OUT, A FEW 
WINDOWS WERE BLOWN OUT, AND AT LEAST TWO LARGE HVAC UNITS WERE 
BLOWN OFF OF THE BUILDING. NUMEROUS SOFTWOOD AND HARDWOOD TREES 
WERE UPROOTED OR SNAPPED IN THE INDUSTRIAL COMPLEX AND IMMEDIATELY
ADJACENT AREAS.

A CELLPHONE TOWER ADJACENT TO THE INDUSTRIAL COMPLEX HAD ALL OF 
THE ANTENNAS BLOWN OFF, BUT THE TOWER ITSELF DID NOT COLLAPSE. 
SOUTHEAST OF THE INDUSTRIAL COMPLEX, MINOR COSMETIC DAMAGE 
OCCURRED TO SOME HOMES ALONG CARTER ROAD IN A RESIDENTIAL 
NEIGHBORHOOD. TREE DAMAGE ASSOCIATED WITH THE TORNADO OCCURRED 
ALONG CARTER ROAD AND SUSSEX ROAD NORTH OF BUCKFIELD TERRACE. THIS
WAS THE AREA WHERE THE TORNADO CIRCULATION REACHED ITS WIDEST 
EXTENT OF AROUND THREE TENTHS OF A MILE. AS THE TORNADO NEARED AND
CROSSED THE PENNSYLVANIA TURNPIKE (I- 276), AN OVERHEAD ROADWAY 
INFORMATION SIGN WAS BLOWN OFF AND A PORTION OF IT LANDED 
DOWNSTREAM NEARLY A HALF MILE AWAY. JUST NORTH OF THE TURNPIKE, 
MINOR COSMETIC DAMAGE OCCURRED TO A HOTEL BUILDING WHERE A TREE 
WAS ALSO UPROOTED IN THE PARKING LOT. A LARGE BILLBOARD WAS BLOWN 
OVER JUST NORTH OF THE TURNPIKE AND SOUTH OF STREET ROAD. A SMALL 
UTILITY BUILDING NEARBY HAD ITS ROOF BLOWN OFF. THE NORTHERN- MOST
EXTENT OF THE DAMAGE OCCURRED ON THE TOSCANA 52 RESTAURANT 
PROPERTY WHERE THE TORNADO BLEW DOWN SOME CHAIN LINK FENCING AND 
UPROOTED A FEW SMALL TREES IN THE PARKING LOT.

THE TORNADO CONTINUED EAST-NORTHEASTWARD ACROSS STREET ROAD 
TOWARD THE FAULKNER CAR DEALERSHIP COMPLEX WHERE IT BEGAN 
INTENSIFYING AND SOMEWHAT NARROWING ITS PATH OF DAMAGE. THE FOUR 
DEALERSHIP SHOWROOMS SUSTAINED SIGNIFICANT DAMAGE WHERE MOST 
WINDOWS WERE BLOWN OUT AND AT LEAST SOME ROOFING MATERIAL WAS 
BLOWN OFF. THE MOST SIGNIFICANT DAMAGE OCCURRED TO THE BUICK/GMC 
SHOWROOM WHERE MOST OF THE ROOFING MATERIAL WAS BLOWN OFF, ALL 
WINDOWS AND DOORS WERE BLOWN OUT, AND EXTERIOR WALLS EXHIBITED 
FRACTURING DUE TO STRESS FROM THE WIND. ROOF HVAC UNITS OF THIS 
BUILDING WERE TOSSED INTO THE PARKING LOT BEHIND THE BUILDING. ALL
OF THE DEALERSHIP SIGNS NEAR THE MAIN ROAD WERE DESTROYED. SCORES
OF NEW AND USED VEHICLES SUSTAINED SIGNIFICANT DAMAGE FROM FLYING
DEBRIS OR FROM BEING PUSHED OR TOSSED TROUGH THE AIR.

THE TORNADO CONTINUED TOWARD THE DEALERSHIP'S MAIN SERVICE GARAGE
WHERE THE MOST SIGNIFICANT DAMAGE OCCURRED. THE SOUTHWESTERN 
PORTION OF THE BUILDING WAS DESTROYED WITH MOST EXTERIOR WALLS 
COLLAPSING COMPLETELY AND ALL ROOFING MATERIAL BLOWN OFF. INTERIOR
WALLS MOSTLY REMAINED STANDING. ROOF HVAC UNITS WERE TOSSED OFF 
OF THE BUILDING WITH ONE UNIT LANDING NEARLY 200 YARDS DOWNSTREAM 
OF THE BUILDING. DAMAGE SUSTAINED TO THE BUILDING DECREASED 
SOMEWHAT TOWARD THE EASTERN END OF IT WHERE PORTIONS OF THE 
EXTERIOR WALLS WERE DAMAGED AND ALMOST ALL GARAGE BAY DOORS WERE 
BLOWN OUT. THE WIND RUSHING THROUGH THE GARAGE AREA CARRIED 
DEBRIS, CAR PARTS, AND TOOLS WELL AWAY FROM THE STRUCTURE 
DOWNSTREAM. SOME VEHICLES NEAR THE MAIN GARAGE BUILDING WERE 
COMPLETELY DESTROYED FROM LARGE PIECES OF FLYING DEBRIS OR FROM 
BEING TOSSED AND DROPPED BACK ONTO THE GROUND. A SMALL PICKUP 
TRUCK WAS CRUSHED FROM A COLLAPSED EXTERIOR WALL. FIVE PEOPLE 
REPORTEDLY SUSTAINED MINOR INJURIES AT THE DEALERSHIP COMPLEX.

THE TORNADO CONTINUED EAST-NORTHEAST TOWARD THE WEISSER HOMES 
MOBILE HOME PARK AND INTO AN AREA OF TREES WHICH SUSTAINED 
SIGNIFICANT DAMAGE. MOST TREE CANOPIES AND LIMBS WERE COMPLETELY 
STRIPPED FROM THE STILL STANDING OR SNAPPED TRUNKS OF HARDWOOD 
TREES IN THIS AREA. A LARGE STORAGE CONTAINER FILLED WITH CAR 
PARTS FROM THE SERVICE GARAGE PARKING LOT UPSTREAM WAS LOFTED INTO
THE AIR AND DROPPED INTO THIS AREA OF TREES. AN UNINHABITED 
MOBILE HOME MODEL WAS LIFTED AND COMPLETELY DESTROYED AT THE 
MOBILE HOME PARK. ANOTHER DOUBLE-WIDE MOBILE HOME HAD A LARGE 
PORTION OF ITS ROOF BLOWN OFF. SEVERAL OTHER MOBILE HOME SUSTAINED
VARYING DEGREES OF DAMAGE AS WELL. A LARGE AMOUNT OF VARIOUS 
DEBRIS FROM THE DEALERSHIP COMPLEX LANDED IN THIS MOBILE HOME 
PARK. NUMEROUS SOFTWOOD AND HARDWOOD TREES NEAR AND JUST 
DOWNSTREAM OF THIS AREA WERE SNAPPED OR UPROOTED ALONG OLD LINCOLN
HIGHWAY.

AT THIS STAGE, THE TORNADO DAMAGE PATH NARROWED CONSIDERABLY AND 
INTENSITY WEAKENED SIGNIFICANTLY AS IT CROSSED OLD LINCOLN HIGHWAY
AND MOVED TOWARD THE LOWE'S AND WALMART SHOPPING CENTERS ON ROUTE
1. THE TORNADO PASSED OVER THESE SHOPPING CENTERS, BUT NO 
STRUCTURAL DAMAGE WAS NOTED TO THESE STRUCTURES. NUMEROUS SMALL 
TREES WERE SNAPPED AND UPROOTED IN THE LARGE PARKING LOT AREA AND 
LINE OF TREES JUST NORTH OF THE BENSALEM TURNPIKE INTERCHANGE. 
SOME EXIT RAMP SIGNS WERE BLOWN DOWN IN THE INTERCHANGE AREA.

THE TORNADO DAMAGE BECAME SOMEWHAT DISCONTINUOUS AS IT CONTINUED 
EAST-SOUTHEAST INTO BENSALEM ACROSS ROUTE 1 AND TOWARD A 
RESIDENTIAL NEIGHBORHOOD. SEVERAL HOMES IN THE NEIGHBORHOOD 
SUSTAINED LOSS OF SOME ROOFING MATERIAL AND OTHER COSMETIC DAMAGE 
IN ADDITION TO SOME TREE DAMAGE. THE TORNADO CONTINUED ACROSS 
ROCKHILL ROAD AND ALONG RICHLIEU ROAD TOWARD THE CHRISTIAN LIFE 
CENTER WHERE SEVERAL TREES WERE SNAPPED OR UPROOTED. THE CHURCH'S 
STEEPLE HAD SOME PANELING BLOWN OFF, BUT THE STEEPLE ITSELF WAS 
NOT DAMAGED OTHERWISE. THE TORNADO CONTINUED WEAKENING AS IT 
CROSSED GALLOWAY ROAD THEN DISSIPATED IN THE BENSALEM TOWNSHIP 
COMMUNITY PARK WHERE SOME MINOR TREE DAMAGE OCCURRED.

NO KNOWN SERIOUS INJURIES OR FATALITIES OCCURRED FROM THIS 
TORNADO.

THE NATIONAL WEATHER SERVICE SURVEY TEAM WOULD LIKE TO THANK THE 
BUCKS COUNTY EMERGENCY MANAGEMENT AGENCY AND PENNSYLVANIA 
EMERGENCY MANAGEMENT AGENCY FOR THEIR ASSISTANCE WITH THIS SURVEY.

TREE DAMAGE BEGAN IN THE AREA OF BRADSHAW RD IN PLUMSTEAD TWP IN 
BUCKS COUNTY, WHERE A FEW SIZABLE LIMBS WERE DOWNED AND A COUPLE 
OF LARGER BUT WEAKENED TREES WERE SNAPPED. THE TORNADO THEN 
ENTERED A CORNFIELD NEAR THE INTERSECTION OF FERRY RD AND POINT 
PLEASANT PIKE. SOME DEGREE OF CONVERGENCE WAS NOTED IN A NARROW 
PATH OF DOWNED CORN, THOUGH IT WAS NOT OVERLY STRONG. IN ADDITION,
SOME TREES ADJACENT TO AND SOUTHEAST OF THE CORNFIELD WERE ALSO 
DAMAGED. THE DAMAGE BECAME MORE SUBSTANTIAL WITH A CLEARER 
ROTATION SIGNATURE OBSERVED IN THE AREA OF RIDGEVIEW DR, WHERE A 
NUMBER OF TREES WERE SNAPPED, FAVORING HIGHER ELEVATION AREAS 
ALONG A RIDGE LINE. THE SNAPPING AND SHEARING OF TREES IN THAT 
AREA AND THE NATURE OF THE DEBRIS FIELD STRONGLY INDICATED 
TORNADIC DAMAGE, WITH THE MAGNITUDE OF DAMAGE MERITING AN EF1 
RATING. THE TORNADO CONTINUED SOUTHEASTWARD THROUGH CARVERSVILLE 
RD AND TO THE AREA OF LONG LN IN BUCKINGHAM TWP. SEVERAL 
RESIDENCES ALONG AND NEAR LONG LN SUSTAINED TREE DAMAGE. THE 
TORNADO IMPACTED MAXIMUCK'S FARM MARKET ON LONG LN, WHERE 
GREENHOUSES SUSTAINED ROOF DAMAGE AND SOME UPLIFT OF THEIR FRAMES.
SOME CONVERGENCE WAS ALSO NOTED IN CROP FIELDS ON THE PROPERTY. 
JUST SOUTHEAST OF THE GREENHOUSES, A BARN ON THE PROPERTY WAS 
HEAVILY DAMAGED WITH A PARTIAL COLLAPSE OF ITS WALLS. HOWEVER, 
JUST BEYOND THE BARN, A LARGE STRETCH OF CORNFIELDS AND A TREE 
LINE BEYOND THE CORNFIELDS WERE LEFT UNTOUCHED, INDICATING THE 
TORNADO LIFTED NEAR THE DAMAGED BARN. 

THE NATIONAL WEATHER SERVICE WOULD LIKE TO THANK THE BUCKS COUNTY
EMERGENCY MANAGEMENT AGENCY AND THE PENNSYLVANIA EMERGENCY 
MANAGEMENT AGENCY FOR THEIR ASSISTANCE IN COMPLETING THIS SURVEY.

THE SUPERCELL STORM WHICH PRODUCED A TORNADO IN PLUMSTEAD TWP 
CYCLED AND PRODUCED ANOTHER TORNADO BEGINNING IN NEW HOPE IN BUCKS
COUNTY, PENNSYLVANIA. TREE DAMAGE BEGAN NEAR RIVER RD JUST WEST 
OF THE DELAWARE RIVER, WITH A PORTION OF RIVER RD CLOSED AND 
IMPASSABLE DUE TO DOWNED TREES. THE TORNADO CROSSED THE DELAWARE 
RIVER AND ENTERED MERCER COUNTY, NEW JERSEY, IN THE AREA OF 
WASHINGTON CROSSING. MULTIPLE REPORTS OF RESIDENTIAL TREE DAMAGE 
WERE RECEIVED FROM WASHINGTON CROSSING, AND THE SURVEY TEAM 
OBSERVED TREE DAMAGE ALONG RIVER RD ON THE NEW JERSEY SIDE OF THE 
DELAWARE RIVER. FROM THERE THE TORNADO CONTINUED SOUTHEAST AND 
CROSSED PLEASANT VALLEY RD. THE FIRST INDICATIONS OF EF2 DAMAGE 
CAME ON THAT ROAD, WITH NUMEROUS LARGE HARDWOOD AND SOFTWOOD TREES
SNAPPED, SHEARED, AND/OR UPROOTED. THE TORNADO CONTINUED 
SOUTHEASTWARD AND CROSSED THROUGH BALDPATE MOUNTAIN. CONTINUED 
HEAVY TREE DAMAGE WAS OBSERVED IN THIS AREA. AN ACCESS ROAD TO THE
TOP OF THE MOUNTAIN WAS BARELY PASSABLE WHEN THE SURVEY TEAM 
REACHED IT IN LATE AFTERNOON, AFTER MANY HOURS OF TREE CLEARING 
WORK BY LOCAL PARKS OFFICIALS AND PRIVATE COMPANIES. HUNDREDS OF 
TREES WERE SNAPPED OR DAMAGED ON THIS MOUNTAIN. DAMAGE CONTINUED 
DOWN THE MOUNTAIN THROUGH FIDDLERS CREEK RD AND CHURCH RD. THE 
TORNADO PATH THEN CROSSED WASHINGTON CROSSING STATE PARK. FURTHER 
DAMAGE WAS OBSERVED JUST SOUTHEAST ALONG BEAR TAVERN RD. IN FACT, 
SOME OF THE LARGEST DOWNED TREES WERE OBSERVED IN THIS AREA. 
HOWEVER, BY THIS POINT DAMAGE BECAME INCREASINGLY UNIDIRECTIONAL 
AS THE STORM'S REAR FLANK DOWNDRAFT LIKELY WRAPPED AROUND THE 
TORNADIC CIRCULATION. SUFFICIENT EVIDENCE OF TORNADIC WINDS STILL 
EXISTED IN THE BEAR TAVERN RD AREA, BUT IT IS ESTIMATED THE 
TORNADO LIFTED SOON AFTER, SHORTLY BEFORE ENTERING MUCH MORE 
DENSELY POPULATED AREAS NEAR THE TRENTON MERCER AIRPORT.

THE NATIONAL WEATHER SERVICE WOULD LIKE TO THANK THE MERCER 
COUNTY OFFICE OF EMERGENCY MANAGEMENT FOR THEIR ASSISTANCE IN 
COMPLETING THIS 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. 


.SLATINGTON TORNADO...

END LAT/LON:            40.765/-75.604

A TORNADO TOUCHED DOWN ON THE GROUNDS OF NORTHERN LEHIGH HIGH 
SCHOOL IN SLATINGTON. SEVERAL TREES WERE SNAPPED OR UPROOTED AT 
THE HIGH SCHOOL, WITH MOST OF THE SNAPPING OCCURRING HIGH UP IN 
THE TREES. A WOODEN DUGOUT ON THE SCHOOL'S BASEBALL FIELD LOST ITS
ROOF, AND SOME UNANCHORED METAL BLEACHERS WERE TOSSED. DAMAGE WAS
MOSTLY BLOWN IN A SIMILAR WEST TO EAST DIRECTION, BUT THERE WAS 
SOME EVIDENCE OF CONVERGENCE ESPECIALLY IN TREE DAMAGE IN THE 
AREA. THE PATH CONTINUED ALMOST STRAIGHT WEST TO EAST FROM THE 
HIGH SCHOOL TO THE SLATINGTON AIRPORT. AN AIRPLANE HANGAR DOOR WAS
BLOWN OUT, AND THERE WAS TREE DAMAGE ON THE AIRPORT PROPERTY. 
DAMAGE BECAME MORE UNIDIRECTIONAL NEAR THE AIRPORT AS THE 
CIRCULATION LIKELY GUSTED OUT. LITTLE IF ANY DAMAGE OCCURRED EAST 
OF THE AIRPORT PROPERTY, AND THAT IS WHERE THE TORNADO PATH IS 
ESTIMATED TO HAVE ENDED.

THE NATIONAL WEATHER SERVICE WOULD LIKE TO THANK MR. LOU RUH FOR 
HIS ASSISTANCE IN COMPLETING THIS SURVEY.
