HAZARDS AFFECTING LAND

———————-

WIND…TROPICAL STORM CONDITIONS WILL CONTINUE OVER PORTIONS OF

THE FLORIDA GULF COAST TODAY.

 

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 AT

THE TIMES OF HIGH TIDE OVER THE NEXT COUPLE OF DAYS…

 

APALACHEE BAY TO WACCASASSA BAY…3 TO 5 FT

FLORIDA WEST COAST SOUTH OF WACCASASSA BAY…1 TO 3 FT

SOUTHEASTERN LOUISIANA EASTWARD TO APALACHEE BAY…1 TO 3 FT

 

THE DEEPEST WATER WILL OCCUR ALONG THE IMMEDIATE COAST IN AREAS OF

ONSHORE FLOW.  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 NATIONAL WEATHER SERVICE OFFICE.

 

RAINFALL…STORM TOTAL ACCUMULATIONS OF 10 TO 20 INCHES ARE EXPECTED

ACROSS MUCH OF NORTHERN AND CENTRAL FLORIDA…WITH A LOCAL MAXIMUM
