SATELLITE...RADAR...SURFACE...AND RECONNAISSANCE AIRCRAFT DATA

AROUND 0000 UTC.  THE INTENSITY OF THE POST-TROPICAL CYCLONE WAS

WINDS GUSTS HAVE BEEN REPORTED ACROSS LONG ISLAND AND THE NEW YORK
METROPOLITAN AREA THIS EVENING.  IN ADDITION...A SIGNIFICANT STORM
SURGE HAS OCCURRED ALONG A LONG STRETCH OF THE MID-ATLANTIC AND
SOUTHERN NEW ENGLAND COAST.
 
ALTHOUGH THE CYCLONE SHOULD STEADILY WEAKEN AS IT MOVES FURTHER
INLAND....CONDITIONS WILL BE SLOW TO IMPROVE AS STRONG WINDS AND
ELEVATED WATER LEVELS WILL PERSIST ALONG THE COAST FOR ANOTHER DAY
OR SO.  HEAVY RAINS ARE ALSO EXPECTED TO CONTINUE OVER A LARGE
AREA OF THE NORTHEASTERN UNITED STATES...POSING A VERY
SIGNIFICANT INLAND FLOOD RISK.  SANDY TOOK A NORTHWARD JOG BEFORE
LANDFALL THIS EVENING AND HAS ALSO SLOWED DOWN.  THE POST-TROPICAL
CYCLONE IS EXPECTED TO SLOW DOWN FURTHER AND TURN NORTHWARD...THEN
NORTHEASTWARD OVER THE NEXT COUPLE OF DAYS.  THE NHC TRACK IS
SIMILAR TO THE PREVIOUS ADVISORY AND IS A BLEND OF THE ECMWF AND
GFS MODELS.
 
NOW THAT SANDY IS A POST-TROPICAL CYCLONE...THE NEXT PUBLIC
ADVISORY WILL BE ISSUED BY THE HYDROMETEOROLOGICAL PREDICTION
CENTER...HPC...AT 500 AM EDT TUESDAY.  THE PUBLIC ADVISORY WILL BE
ISSUED UNDER THE SAME WMO AND AWIPS HEADERS AS THE NHC PUBLIC
ADVISORIES...AND WILL ALSO BE AVAILABLE VIA THE NHC WEBSITE.
HIGH WIND WARNINGS ISSUED BY THE LOCAL NATIONAL WEATHER SERVICE
FORECAST OFFICES REMAIN IN EFFECT FOR A LARGE PORTION OF THE
MID-ATLANTIC AND NORTHEASTERN UNITED STATES.
 
THANKS GO OUT TO THE CREWS OF THE AIR FORCE RESERVE AND NOAA

WOULD ALSO LIKE TO THANK THE LOCAL WEATHER SERVICE OFFICES ACROSS
THE COUNTRY THAT HAVE CONDUCTED SPECIAL RADIOSONDE RELEASES AS SANDY
APPROACHED THE COAST.
