LOCATED NEAR LATITUDE 35.2 NORTH...LONGITUDE 70.5 WEST.  SANDY IS
MOVING TOWARD THE NORTH NEAR 14 MPH...22 KM/H.  A TURN TOWARD THE
NORTHWEST IS EXPECTED TODAY...FOLLOWED BY A TURN TOWARD THE
WEST-NORTHWEST TONIGHT.  ON THE FORECAST TRACK...THE CENTER OF
SANDY WILL MOVE OVER THE COAST OF THE MID-ATLANTIC STATES THIS
EVENING OR TONIGHT.
 
MAXIMUM SUSTAINED WINDS ARE NEAR 75 MPH...120 KM/H...WITH HIGHER
GUSTS.  SANDY IS EXPECTED TO TRANSITION INTO A FRONTAL OR WINTERTIME
LOW PRESSURE SYSTEM PRIOR TO LANDFALL.  HOWEVER...THIS TRANSITION
WILL NOT BE ACCOMPANIED BY A WEAKENING OF THE SYSTEM...AND IN
FACT...A LITTLE STRENGTHENING IS POSSIBLE DURING THIS PROCESS.
SANDY IS EXPECTED TO WEAKEN AFTER MOVING INLAND.
 
HURRICANE FORCE WINDS EXTEND OUTWARD UP TO 175 MILES...
280 KM...MAINLY TO THE SOUTHWEST OF THE CENTER...AND TROPICAL STORM

HAZARDS AFFECTING LAND
----------------------
WIND...TROPICAL STORM CONDITIONS...OR GALE FORCE WINDS...ARE ALREADY
OCCURRING OVER COASTAL NORTH CAROLINA...SOUTHEASTERN VIRGINIA...THE
DELMARVA PENINSULA AND COASTAL NEW JERSEY.  GALE FORCE WINDS ARE
EXPECTED TO ARRIVE ALONG OTHER PORTIONS OF THE MID-ATLANTIC
COAST...LONG ISLAND...AND SOUTHERN NEW ENGLAND...LATER THIS
MORNING.  WINDS OF HURRICANE FORCE COULD REACH THE MID-ATLANTIC
STATES...INCLUDING LONG ISLAND...LATER TODAY.  WINDS AFFECTING THE
UPPER FLOORS OF HIGH-RISE BUILDINGS WILL BE SIGNIFICANTLY STRONGER
THAN THOSE NEAR GROUND LEVEL.
 
STORM SURGE...THE COMBINATION OF AN EXTREMELY DANGEROUS STORM SURGE
AND THE TIDE WILL CAUSE NORMALLY DRY AREAS NEAR THE COAST TO BE
FLOODED BY RISING WATERS. THE WATER COULD REACH THE FOLLOWING
DEPTHS ABOVE GROUND IF THE PEAK SURGE OCCURS AT THE TIME OF HIGH
TIDE...
 
NC NORTH OF SURF CITY INCLUDING PAMLICO/ALBEMARLE SOUNDS...4 TO 6 FT
SE VA AND DELMARVA INCLUDING LOWER CHESAPEAKE BAY...2 TO 4 FT
UPPER AND MIDDLE CHESAPEAKE BAY...1 TO 3 FT
LONG ISLAND SOUND...RARITAN BAY...AND NEW YORK HARBOR...6 TO 11 FT
ELSEWHERE FROM OCEAN CITY MD TO THE CT/RI BORDER...4 TO 8 FT
CT/RI BORDER TO THE SOUTH SHORE OF CAPE COD INCLUDING BUZZARDS
BAY AND NARRAGANSETT BAY...3 TO 6 FT
CAPE COD TO THE MA/NH BORDER INCLUDING CAPE COD BAY...2 TO 4 FT
MA/NH BORDER TO THE U. S./CANADA BORDER...1 TO 3 FT
 
SURGE-RELATED FLOODING DEPENDS ON THE RELATIVE TIMING OF THE SURGE
AND THE TIDAL CYCLE...AND CAN VARY GREATLY OVER SHORT DISTANCES.
GIVEN THE LARGE WIND FIELD ASSOCIATED WITH SANDY...ELEVATED WATER
LEVELS COULD SPAN MULTIPLE TIDE CYCLES RESULTING IN REPEATED AND
EXTENDED PERIODS OF COASTAL AND BAYSIDE FLOODING.  IN ADDITION...
ELEVATED WATERS COULD OCCUR FAR REMOVED FROM THE CENTER OF SANDY.
FURTHERMORE...THESE CONDITIONS WILL OCCUR REGARDLESS OF WHETHER
SANDY IS A TROPICAL OR POST-TROPICAL CYCLONE.  FOR INFORMATION
SPECIFIC TO YOUR AREA...PLEASE SEE PRODUCTS ISSUED BY YOUR LOCAL
NATIONAL WEATHER SERVICE OFFICE.
 
RAINFALL...RAINFALL TOTALS OF 3 TO 6 INCHES ARE EXPECTED OVER FAR
NORTHEASTERN NORTH CAROLINA WITH ISOLATED MAXIMUM TOTALS OF 8
INCHES POSSIBLE. RAINFALL AMOUNTS OF 4 TO 8 INCHES ARE EXPECTED
OVER PORTIONS OF THE MID ATLANTIC STATES...INCLUDING THE DELMARVA
PENINSULA...WITH ISOLATED MAXIMUM AMOUNTS OF 12 INCHES POSSIBLE.
RAINFALL AMOUNTS OF 1 TO 3 INCHES WITH ISOLATED MAXIMUM AMOUNTS
OF 5 INCHES ARE POSSIBLE FROM THE SOUTHERN TIER OF NEW YORK STATE
NORTHEASTWARD THROUGH NEW ENGLAND.
 
SNOWFALL...SNOW ACCUMULATIONS OF 2 TO 3 FEET ARE EXPECTED IN THE
MOUNTAINS OF WEST VIRGINIA...WITH LOCALLY HIGHER TOTALS TONIGHT
THROUGH TUESDAY NIGHT.  SNOWFALL OF 1 TO 2 FEET IS EXPECTED IN
THE MOUNTAINS OF SOUTHWESTERN VIRGINIA TO THE KENTUCKY BORDER...
WITH 12 TO 18 INCHES OF SNOW POSSIBLE IN THE MOUNTAINS NEAR THE
NORTH CAROLINA/TENNESSEE BORDER AND IN THE MOUNTAINS OF WESTERN
MARYLAND.
 
SURF...DANGEROUS SURF CONDITIONS WILL CONTINUE FROM FLORIDA THROUGH
NEW ENGLAND FOR THE NEXT COUPLE OF DAYS.
