PUBLIC INFORMATION STATEMENT...UPDATED
NATIONAL WEATHER SERVICE NEW YORK NY
800 PM EDT WED JUL 8 2009

...DAMAGE FROM OVERNIGHT STORMS IN SOUTHERN WESTCHESTER COUNTY 
CLASSIFIED AS STRAIGHT LINE WINDS...

LOCATION...YONKERS TO EASTCHESTER, WESTCHESTER, NY
DATE...JULY 7, 2009
ESTIMATED TIME...1125 PM TO 1140 PM
ESTIMATED MAXIMUM WIND SPEED...100 MPH (REVISED)
PATH WIDTH...UP TO 1 MILE (VARIED) 
PATH LENGTH...AT LEAST 5 MILES (IN WESTCHESTER)
FATALITIES...NONE
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.
