From the National Weather Service, Friday morning:
For lake okeechobee...the lake level thursday was 13.6 feet above mean sea
level which is below normal for this time of the year. with the current
forecast track...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 port mayaca including moore haven... clewiston...south
bay...belle glade and pahokee. 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 and as high as 20 feet above mean sea level on the east
side. 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. it must be emphasized that the
exact impact on the lake still depends on how close and from what direction
frances approaches the lake.
