...NWS DAMAGE SURVEY FOR 11/13/2021 TORNADO EVENT...

...EF0 TORNADO CONFIRMED IN HAMPTON BAYS TO NORTH SEA, NY...

A NATIONAL WEATHER SERVICE STORM SURVEY TEAM IN COORDINATION WITH
SUFFOLK COUNTY FIRE RESCUE AND EMERGENCY SERVICES CONFIRMED AN 
EF0 TORNADO IN THE HAMPTON BAYS TO NORTH SEA AREA OF SUFFOLK 
COUNTY. A NARROW TORNADO LIKELY TOUCHED DOWN NEAR TIANA CIRCLE, 
PERHAPS COMING IN AS A WATERSPOUT OFF OF SHINNECOCK BAY AND DOWNING
SEVERAL SMALL PINES IN A NORTHEASTERLY DIRECTION. 

THE TORNADIC CIRCULATION LIKELY MOVED NORTHEAST ACROSS SMITH 
CREEK, WITH THE MAGNITUDE OF TREE DAMAGE INCREASING AS IT TOUCHED
DOWN NEAR MILL RACE ROAD. FROM THAT POINT, A 35 YD WIDE PATH OF 
HARDWOOD TREES WAS OBSERVED TO BE EITHER UPROOTED AND LAYING IN A 
NORTHEAST DIRECTION, SNAPPED AT THE TRUNK, OR HAVING LARGE 
BRANCHES SHEARED OFF, CONTINUING NORTHEAST THROUGH COLUMBIA STREET
AND WASHINGTON AVENUE, TO HUDSON STREET AND SHERMAN AVENUE, AND 
THEN UP TO LYNNCLIFF ROAD AND PALO ALTO DRIVE. IN ADDITION, MINOR 
ROOF AND SIDING DAMAGE WAS OBSERVED FOR A FEW HOUSES ALONG THIS 
PATH. THIS INCLUDED A HOMEOWNER ON HUDSON STREET REPORTING THAT A
SCREEN DOOR WAS PULLED OFF THE REAR OF THEIR HOME AND TOSSED 50 
YARDS NORTHEAST OF THEIR HOME, AS WELL AS A HEAVY WROUGHT IRON 
TABLE AND LARGE GAS GRILL PICKED UP AND PINNED AGAINST THEIR 
FENCE. IN ADDITION, A HOMEOWNER ON LYNNCLIFF ROAD REPORTED THEIR 
ROOF SHINGLES STANDING ON EDGE AS THE TORNADIC CIRCULATION CAME 
THROUGH.

THEREAFTER, THE TORNADIC CIRCULATION LIKELY CROSSED THE EASTERN 
HALF OF SHINNECOCK BAY, WITH AN INTERMITTENT 35 YD WIDTH PATH OF 
MAINLY HARDWOOD TREE DAMAGE SKIPPING ALONG PECONIC ROAD AND 
MONTAUK HIGHWAY, BEFORE LIKELY CROSSING SHINNECOCK HILLS GOLF 
COURSE AND A HEAVILY WOODED AREA TO THE NORTHEAST. THE TORNADIC 
CIRCULATION LIKELY DISSIPATED AFTER PRODUCING TREE DAMAGE ON MARYS
LANE, EAST OF NORTH SEA RD IN NORTH SEA. NO VISIBLE DAMAGE WAS 
NOTED OR REPORTED TO THE NORTHEAST OF THIS LOCATION, INCLUDING THE
SOUTHAMPTON YOUTH SPORTS CENTER.

BASED ON RADAR VELOCITY SIGNATURES AND DAMAGE ORIENTATION IN 
RELATION TO THE GENERAL NORTHEAST MOTION OF THE PARENT STORM, THE 
DAMAGE SURVEY ABOVE IS DETERMINED TO BE EF0 TORNADIC DAMAGE WITH 
WINDS OF 70 TO 85 MPH.

THE NWS WOULD LIKE TO THANK SUFFOLK COUNTY FIRE RESCUE AND 
EMERGENCY SERVICES IN ASSISTING IN THE SURVEY AND HELPING 
FORMULATE THIS PRELIMINARY DAMAGE ASSESSMENT.
