IS FORECAST TO CONTINUE THROUGH SUNDAY. A TURN TOWARD THE NORTH IS
FORECAST ON SUNDAY NIGHT...FOLLOWED BY A TURN TOWARD THE NORTH-
NORTHWEST ON MONDAY. ON THE FORECAST TRACK THE CENTER OF SANDY
WILL MOVE PARALLEL TO THE SOUTHEAST COAST OF THE UNITED STATES
THROUGH THE WEEKEND...AND APPROACH THE COAST OF THE MID-ATLANTIC
STATES LATE MONDAY.
MAXIMUM SUSTAINED WINDS REMAIN NEAR 75 MPH...120 KM/H...WITH HIGHER

HAZARDS AFFECTING LAND
----------------------
WIND...TROPICAL STORM CONDITIONS ARE EXPECTED TO REACH THE TROPICAL
STORM WARNING AREA IN THE CAROLINAS WITHIN THE NEXT FEW HOURS...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. WINDS TO NEAR HURRICANE FORCE COULD
REACH THE MID-ATLANTIC STATES...INCLUDING LONG ISLAND...BY LATE
MONDAY.
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 AND MIDDLE 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.

5 INCHES ARE POSSIBLE ACROSS PARTS OF SOUTHERN NEW YORK INTO NEW
