...SUMMARY...

THE NATIONAL WEATHER SERVICE (NWS) SURVEYED DAMAGE IN THE 
MASSACHUSETTS TOWNS OF DUDLEY, WEBSTER, SUTTON, AND GRAFTON. WE 
CONCLUDED THAT A HIGH-END EF-1 TORNADO ON THE ENHANCED FUJITA SCALE 
STRUCK DUDLEY AND WEBSTER, WITH THE MOST SIGNIFICANT DAMAGE IN 
WEBSTER. MAXIMUM WIND SPEEDS THERE WERE ESTIMATED AT 110 MPH. THE 
TORNADO WAS 300 YARDS WIDE AND TRAVELED 0.5 MILES IN LENGTH FROM 948 
AM TO 949 AM. TREE DAMAGE IN SUTTON AND GRAFTON WAS NOT INDICATIVE 
OF A TORNADO. ALL OF THE DAMAGE WAS THE RESULT OF THE SAME STORM 
THAT PRODUCED THE EF-0 TORNADO IN NORTHEAST CONNECTICUT.

IN JUST A COUPLE OF MINUTES, IT WREAKED HAVOC IN THE EASTERNMOST 
PART OF DUDLEY FROM ROUGHLY ROUTE 12 (SCHOFIELD AVENUE) TO WEST OF 
LAPRISE COURT NORTHEASTWARD ONTO MAIN STREET IN WEBSTER, AND LIFTED 
NEAR THE FRENCH RIVER BY OXFORD AVENUE. MANY TREES WERE SNAPPED AND 
DEBARKED. IN WEBSTER, A GAS STATION OVERHANG WAS TWISTED. AN OLD 
BRICK ROOFTOP WAS DAMAGED, WITH BRICKS HAVING FALLEN ONTO MAIN 
STREET. THE RUBBER ROOF COVERING OF ANOTHER BUILDING WAS PEELED 
COMPLETELY OFF. WINDOWS WERE BLOWN OUT AT A BUSINESS ON MAIN STREET 
AND THE STREET WAS LITTERED WITH BROKEN GLASS. THE SIDE WALLS OF AN 
APARTMENT COMPLEX WERE BENT SLIGHTLY OUTWARD TOWARD THE TORNADO. 
WINDOW SCREENS WERE SUCKED OUTWARD. A CAR WINDSHIELD AND SIDE MIRROR 
WAS DAMAGED. THERE WERE OTHER REPORTS OF TREES FALLEN ONTO CARS. 
UTILITY POLES WERE SNAPPED AND NUMEROUS WIRES WERE DOWNED.

INITIALLY, A SEVERE THUNDERSTORM WARNING WAS ISSUED 17 MINUTES 
BEFORE THE DAMAGE OCCURRED. IT WAS UPGRADED TO A TORNADO WARNING 13 
MINUTES PRIOR TO THE TORNADO TOUCHDOWN IN DUDLEY.

TORNADO WARNINGS TRIGGER WIRELESS EMERGENCY ALERTS AND NEARLY 
EVERYONE WE SPOKE TO HAD HEARD THE WARNING VIA THEIR CELL PHONES 
WELL IN ADVANCE. THIS UNDOUBTEDLY PLAYED A BIG ROLE IN THE FACT THAT 
THERE WERE NO FATALITIES. ACCORDING TO MEDIA REPORTS THERE WAS ONE 
MINOR INJURY WHEN AN AUTOMOBILE WAS STRUCK BY FALLING DEBRIS.

THE NWS WOULD LIKE TO THANK MANY PEOPLE FOR THEIR ASSISTANCE WITH 
CONDUCTING THIS SURVEY. IN PARTICULAR, SPECIAL THANKS TO THE AMATEUR 
RADIO SKYWARN OPERATORS, WHO ACCURATELY AND QUICKLY FOUND THE 
DAMAGED AREAS AND HELPED LINK UP THE NWS WITH ON-SCENE STATE 
EMERGENCY MANAGEMENT OFFICIALS. WE WOULD LIKE TO THANK THE 
MASSACHUSETTS EMERGENCY MANAGEMENT AGENCY FOR PATIENTLY DRIVING THE 
SURVEY TEAM FROM WOODSTOCK, CT THROUGH SUTTON, MA. THE CONNECTICUT 
DEPARTMENT OF HOMELAND SECURITY AND EMERGENCY MANAGEMENT ALSO HELPED 
US BY HAVING THEIR REGION IV DIRECTOR TRAVEL WITH THE TEAM. THE 
EMERGENCY MANAGEMENT DIRECTORS AND FIRE AND POLICE OFFICIALS IN THE 
AFOREMENTIONED TOWNS WERE VERY HELPFUL AS WELL. WE WOULD ESPECIALLY 
LIKE TO THANK THE PEOPLE WHO TOOK TIME OUT TO SPEAK WITH US AND 
ALLOW US TO PHOTOGRAPH THEIR DAMAGED PROPERTY.
