TOWARD THE NORTHEAST IS EXPECTED SATURDAY NIGHT OR SUNDAY. ON THE
FORECAST TRACK...THE CENTER OF SANDY WILL CONTINUE MOVING AWAY FROM
THE NORTHWESTERN BAHAMAS OVERNIGHT.

MAXIMUM SUSTAINED WINDS REMAIN NEAR 75 MPH...120 KM/H...WITH HIGHER
GUSTS. SANDY IS A CATEGORY ONE HURRICANE ON THE SAFFIR-SIMPSON

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 CONTINUE OVER THE WARNING AREA ALONG THE
EAST COAST OF FLORIDA OVERNIGHT. TROPICAL STORM CONDITIONS ARE
EXPECTED IN THE TROPICAL STORM WARNING AREA IN THE CAROLINAS
SATURDAY AND SATURDAY NIGHT. TROPICAL STORM CONDITIONS ARE POSSIBLE
IN THE WATCH AREAS TONIGHT THROUGH SATURDAY NIGHT.

RAINFALL...ADDITIONAL RAINFALL ACCUMULATIONS OF 1 TO 2 INCHES ARE
EXPECTED OVER PORTIONS OF THE BAHAMAS...WITH ISOLATED MAXIMUM
TOTALS OF 12 INCHES POSSIBLE. ADDITIONAL RAINFALL ACCUMULATIONS OF
1 TO 2 INCHES ARE EXPECTED OVER PORTIONS OF EASTERN FLORIDA...WITH
ISOLATED MAXIMUM AMOUNTS OF 6 INCHES POSSIBLE. RAINFALL TOTALS OF 3
TO 6 INCHES ARE POSSIBLE OVER FAR EASTERN NORTH CAROLINA.
 
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...
 
BAHAMAS WITHIN THE WARNING AREA...3 TO 5 FT
FLORIDA COAST WITHIN WARNING AREA...1 TO 3 FT
NORTH CAROLINA WITHIN THE WARNING AREA...3 TO 5 FT
REMAINDER OF NORTH CAROLINA AND SE VIRGINIA INCLUDING LOWER
CHESAPEAKE BAY...2 TO 4 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
PERIODS OF COASTAL AND BAYSIDE FLOODING. FOR INFORMATION SPECIFIC
TO YOUR AREA...PLEASE SEE PRODUCTS ISSUED BY YOUR LOCAL WEATHER
OFFICE.

SURF...DANGEROUS SURF CONDITIONS ARE OCCURRING FROM FLORIDA THROUGH
THE CAROLINAS AND WILL CONTINUE FOR THE NEXT COUPLE OF DAYS. THESE
CONDITIONS ARE EXPECTED TO SPREAD INTO THE MID-ATLANTIC AND
NORTHEASTERN STATES OVER THE WEEKEND.
