THE NATIONAL WEATHER SERVICE CONDUCTED A STORM SURVEY THAT BEGAN
NEAR THE TOWN LINES OF CONESUS AND SPRINGWATER AND PROCEEDED
EAST-SOUTHEAST FROM THERE WITH CONSISTENT TREE DAMAGE THROUGH
WEBSTER'S CROSSING. DAMAGE BEGAN JUST TO THE WEST OF ROUTE 15 AND
CONTINUED ACROSS THE INTERSECTION OF MAIN STREET AND ROUTE 15,
THROUGH A SWAMP, AND THROUGH A SECOND WOODED AREA CROSSING 
MARROWBACK ROAD.

FROM THE BEGINNING OF THE TRACK JUST TO THE WEST OF ROUTE 15, 
MULTIPLE HARDWOOD AND SOFTWOOD TREES WERE SHEARED OFF MID-TRUNK
OR UPROOTED. THE PATH OF DAMAGE CONTINUED BEHIND THREE HOUSES
ALONG ROUTE 15 LEAVING THE HOMES UNSCATHED BUT CRUSHING AN
OUTDOOR SHED AND ABOVE GROUND SWIMMING POOL. A TRAILERED BOAT WAS
MOVED AROUND FIVE FEET, AND AN ANTIQUE PLOW WAS LIKEWISE MOVED
FROM ITS PRE-STORM POSITION. THE TORNADO CONTINUED EAST OF ROUTE 15,
UPROOTING MULTIPLE HARDWOOD TREES ALONG MAIN STREET BEFORE CROSSING
A SWAMP. ON THE EAST SIDE OF THE SWAMP, MINOR SIDING DAMAGE WAS DONE
TO A MOBILE HOME BEFORE THE TORNADO CRESTED A HILLTOP. AS THE TORNADO
CAME DOWN THE EAST SIDE OF THE HILL, ONCE AGAIN, DOZENS OF HARDWOOD
TREES WERE SHEARED OFF AT THE TRUNK OR UPROOTED AS IT CROSSED 
MARROWBACK ROAD BEFORE LIFTING JUST TO THE EAST OF THE ROAD.

DUE TO THE QUANTITY AND CONSISTENCY OF HARDWOOD TREE DAMAGE, THE
NATIONAL WEATHER SERVICE ESTIMATES MAXIMUM WIND SPEEDS OF 110 MPH
WITH THIS TORNADO, WHICH RATES IT AS AN EF-1 ON THE ENHANCED FUJITA
SCALE.

THE NATIONAL WEATHER SERVICE EXTENDS THANKS TO OUR PARTNERS AT THE
LIVINGSTON COUNTY EMERGENCY MANAGEMENT OFFICE AND THE SPRINGWATER
FIRE DEPARTMENT FOR THEIR ASSISTANCE IN THE STORM SURVEY AS WELL AS
THE NUMEROUS LOCAL RESIDENTS FOR THEIR VALUABLE INFORMATION AND
ASSISTANCE WITH THE SURVEY PROCESS.

&&

FOLLOWING CATEGORIES:
