DISCUSSION AND 48-HOUR OUTLOOK
------------------------------
AT 200 AM EDT...0600 UTC...THE CENTER OF HURRICANE SANDY WAS
LOCATED NEAR LATITUDE 31.5 NORTH...LONGITUDE 73.7 WEST.  SANDY IS
MOVING TOWARD THE NORTHEAST NEAR 14 MPH...22 KM/H...AND THIS GENERAL
MOTION IS FORECAST TO CONTINUE THROUGH TODAY.  A TURN TOWARD THE
NORTH IS FORECAST TONIGHT...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 MONDAY NIGHT.
 
MAXIMUM SUSTAINED WINDS ARE NEAR 75 MPH...120 KM/H...WITH HIGHER
GUSTS.  WHILE LITTLE CHANGE IN STRENGTH IS FORECAST DURING THE NEXT
COUPLE OF DAYS...SANDY IS EXPECTED TO REMAIN A LARGE AND POWERFUL
CYCLONE.
 
HURRICANE FORCE WINDS EXTEND OUTWARD UP TO 105 MILES...165 KM...FROM
THE CENTER...AND TROPICAL STORM FORCE WINDS EXTEND OUTWARD UP TO 520
MILES...835 KM.  NOAA BUOY 41036...LOCATED IN ONSLOW BAY NEAR THE

HAZARDS AFFECTING LAND
----------------------
WIND...TROPICAL STORM CONDITIONS ARE SPREADING ACROSS THE COAST OF
NORTH CAROLINA IN THE TROPICAL STORM WARNING AREA...AND THESE
SHOULD CONTINUE THROUGH TODAY.  GALE FORCE WINDS ARE EXPECTED TO
ARRIVE ALONG PORTIONS OF THE MID-ATLANTIC COAST LATER TODAY...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 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 SOUTH OF SURF CITY...1 TO 3 FT
NC NORTH OF SURF CITY INCLUDING PAMLICO/ALBEMARLE SNDS...4 TO 6 FT
SE VA AND DELMARVA INCLUDING LOWER CHESAPEAKE BAY...2 TO 4 FT
UPPER AND MIDDLE CHESAPEAKE BAY...1 TO 2 FT
LONG ISLAND SOUND AND RARITAN BAY...5 TO 10 FT
ELSEWHERE FROM OCEAN CITY MD TO THE CT/RI BORDER...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.
RAINFALL AMOUNTS OF 1 TO 3 INCHES WITH ISOLATED MAXIMUM AMOUNTS OF
5 INCHES ARE POSSIBLE ACROSS PARTS OF SOUTHERN NEW YORK INTO NEW
ENGLAND.
 
SURF...DANGEROUS SURF CONDITIONS WILL CONTINUE FROM FLORIDA THROUGH
THE MID-ATLANTIC FOR THE NEXT COUPLE OF DAYS AND SPREAD INTO THE
NORTHEASTERN STATES ON SUNDAY.
