HAZARDS AFFECTING LAND
----------------------
EVEN THOUGH ISAAC IS NO LONGER A HURRICANE...LIFE-THREATENING
HAZARDS FROM STORM SURGE AND INLAND FLOODING ARE STILL OCCURRING.

STORM SURGE...THE COMBINATION OF A 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...

* MISSISSIPPI AND SOUTHEASTERN LOUISIANA...6 TO 12 FT
* SOUTH-CENTRAL LOUISIANA...3 TO 6 FT
* ALABAMA...2 TO 4 FT
* FLORIDA PANHANDLE AND APALACHEE BAY...1 TO 2 FT

THE DEEPEST WATER WILL OCCUR ALONG THE IMMEDIATE COAST IN AREAS OF
ONSHORE WINDS. SURGE-RELATED FLOODING DEPENDS ON THE RELATIVE
TIMING OF THE SURGE AND THE TIDAL CYCLE...AND CAN VARY GREATLY OVER
SHORT DISTANCES. FOR INFORMATION SPECIFIC TO YOUR AREA...PLEASE
SEE PRODUCTS ISSUED BY YOUR LOCAL WEATHER SERVICE OFFICE. NEAR THE
COAST...THE SURGE WILL BE ACCOMPANIED BY LARGE AND DANGEROUS WAVES.

STORM SURGE VALUES NEAR 7 FEET HAVE RECENTLY BEEN REPORTED AT
WAVELAND MISSISSIPPI.

WIND...TROPICAL STORM CONDITIONS WILL CONTINUE ACROSS THE WARNING
AREA THROUGH TONIGHT.

WINDS AFFECTING THE UPPER FLOORS OF HIGH-RISE BUILDINGS WILL BE
SIGNIFICANTLY STRONGER THAN THOSE NEAR GROUND LEVEL. AT ABOUT THE
30TH STORY...WINDS WOULD LIKELY BE ONE SAFFIR-SIMPSON CATEGORY
STRONGER THAN AT THE SURFACE.

7 TO 14 INCHES...WITH POSSIBLE ISOLATED MAXIMUM AMOUNTS OF 25
INCHES...OVER MUCH OF LOUISIANA...SOUTHERN AND CENTRAL
