DATE...JULY 7, 2009
ESTIMATED TIME...1125 PM TO 1140 PM

INJURIES...1

METEOROLOGISTS FROM THE NATIONAL WEATHER SERVICE (NWS) NEW YORK, NY
FORECAST OFFICE CONDUCTED A SURVEY OF THE DAMAGE IN SOUTHERN
WESTCHESTER COUNTY THIS AFTERNOON. THE METEOROLOGISTS CONCLUDED THAT
THE DAMAGE WAS THE RESULT OF STRAIGHT LINE WINDS.

THE SAME STORM THAT PRODUCED STORM DAMAGE IN BERGEN COUNTY IN
NORTHEASTERN NEW JERSEY MOVED INTO YONKERS AROUND 1125 PM AS THE
STORM INTENSIFIED.  DOPPLER WEATHER RADAR ANALYSIS WOULD CLASSIFY
THE STORM AS A SUPERCELL WITH A STRONG MESOCYCLONE AT THIS TIME. A
LARGE AREA OF VERY STRONG DOWNBURST WINDS DOWNED NUMEROUS LARGE
TREES THAT FELL ON STRUCTURES, POWERLINES AND CARS. THE WORST DAMAGE
OBSERVED IN THE AREA WAS IN TREVOR PARK AROUND THE HUDSON RIVER
MUSEUM WHERE WINDS WERE ESTIMATED TO HAVE GUSTED UP TO AN ESTIMATED
100 MPH. SOME MINOR DAMAGE APPEARED TO OCCUR TO THE ROOF OF THE
MUSEUM WITH A FEW SHINGLES BLOWN OFF. NEARLY ALL TREES APPEARED TO
HAVE FALLEN TO THE EAST OR SOUTHEAST. THE DAMAGE AREA EXTENDED EAST
TO NORTH BROADWAY AND INTO GRANT PARK ON PARK AVE WHERE NUMEROUS
LARGE TREES WERE ALSO KNOCKED OVER FALLING TO THE EAST OR SOUTHEAST.
DOWNED LARGE TREES WERE ALSO OBSERVED IN OAKLAND CEMETERY.

DOWNED TREES WERE ALSO OBSERVED IN MOUNT VERNON ALONG WEST STREET
AND MACQUESTEN PARKWAY NORTH WHERE WINDS OF 70 MPH WERE ESTIMATED TO
HAVE OCCURRED. AGAIN, ALL TREES APPEARED TO FALL TO THE SOUTHEAST.
THERE WAS ADDITIONAL TREE DAMAGE TO A LESSER DEGREE TO THE NORTH
OBSERVED ALONG AND NEAR THE CROSS COUNTY PARKWAY.

IN BRONXVILLE, SEVERAL TREES WERE SEEN DOWNED ALONG THE BRONX RIVER
PARKWAY FROM EXITS 1 TO 3. IN EASTCHESTER/TUCKAHOE, SEVERAL LARGE
TREES WERE DOWNED IN THE VICINITY OF RIDGE AND GOVERNORS ROADS. A
LARGE TREE HERE FELL ON POWERLINES SNAPPING A TELEPHONE POLE IN
HALF. WINDS IN THIS AREA WERE ESTIMATED AT 80 MPH.

IN ADDITION TO THE WIND DAMAGE, THERE WAS EXTENSIVE HAIL FROM THE
STORM ALONG WITH TORRENTIAL RAIN. THE HAIL ACCUMULATED TO SEVERAL
INCHES IN YONKERS AND WAS STILL VISIBLE THIS MORNING. RAIN SWEPT THE
HAIL INTO SOME LOCATIONS TO DEPTH OVER A FOOT. IN ONE LOCATION ON
HOOVER ROAD IN NORTHERN YONKERS...UP TO 4 FEET OF HAIL ACCUMULATED
INSIDE A HOME AFTER THE DRAINAGE BECAME CLOGGED.

LASTLY, IN NORTHERN NASSAU COUNTY ON LONG ISLAND...A LIMITED SURVEY
OF JERICHO AND SEA CLIFF DID NOT REVEAL ANY SIGNIFICANT DAMAGE.

THE NWS EXTENDS ITS SINCERE APPRECIATION TO THE WESTCHESTER COUNTY
EXECUTIVE AND OFFICE OF EMERGENCY MANAGEMENT FOR THEIR CONTINUED
SUPPORT AND COLLABORATION WITH THIS AND PAST STORM EVENTS. WE ALSO
EXTEND OUR APPRECIATION TO THE RESIDENTS AND EMERGENCY RESPONDERS OF
SOUTHERN WESTCHESTER COUNTY THAT GRACIOUSLY TOOK THE TIME TO
DESCRIBE THE STORM TO US AND ASSIST WITH THE SURVEY.
