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

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.
