ISOLATED MAXIMUM TOTALS OF 20 INCHES POSSIBLE.  THESE RAINS MAY
PRODUCE LIFE-THREATENING FLASH FLOODS AND MUD SLIDES..ESPECIALLY IN

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

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.
