LOCATED NEAR LATITUDE 29.7 NORTH...LONGITUDE 75.6 WEST.  SANDY
IS MOVING TOWARD THE NORTHEAST NEAR 11 MPH...18 KM/H...AND THIS
GENERAL MOTION IS FORECAST TO CONTINUE THROUGH SUNDAY.  A TURN
TOWARD THE NORTH IS FORECAST SUNDAY NIGHT OR EARLY MONDAY. ON THE
FORECAST TRACK THE CENTER OF SANDY WILL CONTINUE MOVING AWAY FROM
THE NORTHWESTERN BAHAMAS AND WILL MOVE PARALLEL TO THE SOUTHEAST
COAST OF THE UNITED STATES THROUGH THE WEEKEND.

NEXT COUPLE OF DAYS.

HAZARDS AFFECTING LAND
----------------------
WIND...TROPICAL STORM CONDITIONS WILL CONTINUE IN GREAT ABACO AND
GRAND BAHAMA ISLANDS FOR THE NEXT FEW HOURS.  TROPICAL STORM
CONDITIONS ARE EXPECTED TO FIRST REACH THE TROPICAL STORM WARNING
AREA IN THE CAROLINAS THIS AFTERNOON OR EVENING...AND SPREAD
NORTHWARD TONIGHT AND SUNDAY.  TROPICAL STORM CONDITIONS ARE
POSSIBLE IN THE WATCH AREAS THROUGH TONIGHT.  GALE FORCE WINDS
ARE EXPECTED TO ARRIVE ALONG PORTIONS OF THE MID-ATLANTIC COAST
BY LATE SUNDAY OR SUNDAY NIGHT AND REACH LONG ISLAND AND SOUTHERN
NEW ENGLAND BY MONDAY MORNING.
 
STORM SURGE...THE COMBINATION OF A 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...
 
FL EAST COAST NORTH OF CAPE CANAVERAL...1 TO 2 FT
NC SOUTH OF SURF CITY...1 TO 3 FT
NC NORTH OF SURF CITY INCLUDING PAMLICO/ALBERMARLE SNDS...3 TO 5 FT
SE VA AND DELMARVA INCLUDING LOWER CHESAPEAKE BAY...2 TO 4 FT
UPPER CHESAPEAKE BAY...1 TO 2 FT
OCEAN CITY MD TO THE CT/RI BORDER...4 TO 8 FT
LONG ISLAND SOUND...RARITAN BAY...AND DELAWARE BAY...4 TO 8 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
EASTERN 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.
 
SURF...DANGEROUS SURF CONDITIONS WILL CONTINUE FROM FLORIDA THROUGH
THE CAROLINAS FOR THE NEXT COUPLE OF DAYS AND SPREAD INTO THE MID-
ATLANTIC AND NORTHEASTERN STATES BY SUNDAY.
