...NWS DAMAGE SURVEY FOR 11/13/2021 TORNADO IN SUFFOLK COUNTY...

...EF0 TORNADO CONFIRMED IN EAST ISLIP, NY...

OVERVIEW...A NATIONAL WEATHER SERVICE STORM SURVEY TEAM CONFIRMED AN 
EF0 TORNADO IN EAST ISLIP, NY, A NARROW TORNADO OF 50 YD WIDTH 
LIKELY TOUCHED DOWN AT THE SOUTHWESTERN END OF HOLLINS LANE, AND 
THEN CONTINUED NORTHEAST OVER BRUSHWOOD COURT, BAYVIEW AVENUE, 
JOSEPHINE LANE AND THEN FINALLY OVER KAY COURT, BEFORE LIFTING OVER 
THE JOHN F KENNEDY ELEMENTARY SCHOOL SPORT FIELDS. A FEW DOZEN LARGE 
OAK, MAPLE AND PINE TREES WERE UPROOTED AND LAYING IN A EAST OR 
NORTHEAST DIRECTION.
SEVERAL TREES WERE ALSO SNAPPED AT THE TRUNK OR HAD LARGE BRANCHES 
SHEARED OFF ALONG THIS PATH. IN ADDITION, MINOR ROOF AND SIDING 
DAMAGE WAS OBSERVED FOR SEVERAL HOUSES, AS WELL AS LEAF SPLATER ON 
SOUTH AND EAST SIDES OF SEVERAL HOUSES. THIS TORNADIC CIRCULATION 
WAS LIKELY ON THE NORTHWEST SIDE OF A 400 YD SWATH OF 65 TO 75 MPH 
WEST TO SOUTHWEST STRAIGHT LINE WINDS CAUSING ISOLATED LARGE TREES 
TO BE UPROOTED AND SEVERAL LARGE LIMBS BROKEN. 

AS MENTIONED, THE TORNADO LIKELY LIFTED OVER THE JOHN F KENNEDY 
ELEMENTARY SCHOOL SPORT FIELDS, BECOMING A FUNNEL CLOUD. THIS FUNNEL 
CLOUD MAY HAVE BREIFLY TOUCHED DOWN AS A WEAK TORNADO IN THE FROG 
LANE AND JADE STREET AREA OF OAKDALE, RESULTING IN A VERY LARGE, BUT 
PARTIALLY ROTTED, OAK TREE TO TOPPLE ONTO AND DESTROY A HOME. THE 
FUNNEL CLOUD WAS VIDEOTAPED BY THE PUBLIC, LOOKING SOUTHWEST FROM 
THE OLD NAVY DEPARTMENT STORE ON JOHNSON AVENUE (JUST NORTH OF 
SUNRISE HIGHWAY), BUT NO FURTHER DAMAGE WAS NOTED WITH THIS STORM.

BASED ON RADAR VELOCITY SIGNATURES AND DAMAGE ORIENTATION IN RELATION TO
THE GENERAL NORTHEAST MOTION OF THE PARENT STORM, THIS WAS DETERMINED TO 
BE TORNADO DAMAGE, WITH DEGREE OF DAMAGE INDICATING EF0 DAMAGE.

THE NWS WOULD LIKE TO THANK SUFFOLK COUNTY FIRE RESCUE AND EMERGENCY SERVICES, 
NEW YORK STATE DIVISION OF HOMELAND SECURITY AND EMERGENCY SERVICES
LONG ISLAND SECTOR, AND NEW YORK STATE POLICE IN ASSISTING IN THE SURVEY 
AND HELPING FORMULATE THIS PRELIMINARY DAMAGE ASSESSMENT.
