VALID 272331Z - 280100Z

THE SEVERE WEATHER THREAT FOR TORNADO WATCH 811 CONTINUES.

THE TORNADO THREAT ASSOCIATED WITH HURRICANE IRENE WILL CONTINUE TO
SPREAD NNEWD ALONG THE MID-ATLANTIC COAST INTO THE LONG ISLAND AREA.
A NEW TORNADO WATCH WILL BE NEEDED ALONG THE COAST OF DE...NJ...SE
NY AND ACROSS LONG ISLAND THIS EVENING.

THE CENTER OF HURRICANE IRENE IS CURRENTLY LOCATED ABOUT 300 STATUTE
MILES SOUTH OF NEW YORK CITY WITH SEVERAL RAINBANDS EXTENDING NWD
ALONG THE COASTS OF DE...NJ AS FAR NORTH AS LONG ISLAND. AT THIS
POINT...THE TORNADO THREAT APPEARS TO BE THE GREATEST WITH THE
MIDDLE RAINBAND EXTENDING FROM NEAR DOVER OFFSHORE ABOUT 100 STATUTE
MILES. CELLS WITHIN THIS BAND APPEAR MORE DISCRETE WITH WSR-88D VWPS
SUGGESTING LOW-LEVEL SHEAR IS CURRENTLY MAXIMIZED AROUND 50 KT.
LOW-LEVEL SHEAR WILL INCREASE IN SERN NY AS THE BAND MOVES NWD DUE
TO THE APPROACH OF IRENE. A FEW TORNADOES COULD OCCUR IN NRN NJ AND
SERN NY WHERE A TORNADO WATCH WILL BE NEEDED THROUGH MUCH OF THE
OVERNIGHT PERIOD.
