From NWS Miami:
FOR LAKE OKEECHOBEE...ASSUMING THE CURRENT FORECAST TRACK...NORTHEAST WINDS WOULD BLOW THE WATER IN LAKE OKEECHOBEE FIRST TOWARD THE SOUTHWEST AND LATER TOWARD THE SOUTH TOWARD THE HOOVER DIKE IN GLADES...HENDRY...AND WESTERN PALM BEACH COUNTIES. THE LAKE LEVEL ON WEDNESDAY WAS 13.6 FEET ABOVE MEAN SEA LEVEL WHICH IS BELOW
NORMAL FOR THIS TIME OF YEAR. THE WATER WOULD BE PUSHED UP AS MUCH AS 8 TO 10 FEET HIGHER ON THE LAKE SIDE OF THE DIKE IN GLADES... HENDRY...AND WESTERN PALM BEACH COUNTIES FROM THE MOUTH OF FISHEATING CREEK ALL THE WAY AROUND TO PAHOKEE INCLUDING MOORE HAVEN... CLEWISTON...LAKE HARBOR...SOUTH BAY AND BELLE GLADE. THE MAXIMUM
STORM TIDE INSIDE HOOVER DIKE WOULD THEREFORE BE ABOUT 24 FEET ABOVE MEAN SEA LEVEL ON THE WEST AND SOUTH SIDES OF THE LAKE. THE HOOVER DIKE PROTECTS INHABITED AREAS TO AT LEAST 30 FEET ABOVE MEAN SEA LEVEL. RITTA...KREAMER AND TORRY ISLANDS WOULD BE FLOODED AT THESE LEVELS INCLUDING SOME CAMPGROUNDS AND ROADS. THE EXACT IMPACT ON THE LAKE STILL DEPENDS ON HOW CLOSE AND FROM WHAT DIRECTION FRANCES APPROACHES THE LAKE.
