Fred is expected to continue moving near the north coast of central
Cuba tonight, pass near or west of the lower Florida Keys on
Saturday, and move across the eastern Gulf of Mexico Saturday 
night and Sunday. 

Maximum sustained winds are near 35 mph (55 km/h) with higher gusts.
Little change in strength is expected through early Saturday. After

RAINFALL:  Fred is expected to produce the following rainfall
amounts:

Portions of Cuba...2 to 5 inches with isolated maximum totals of 8
inches. This rainfall may lead to scattered flash flooding.

Across the Bahamas...1 to 3 inches, with isolated maximum totals of
5 inches.

Tonight through Monday, 3 to 6 inches of rain is anticipated across
the Keys, southern and central Florida north towards the Big Bend,
with isolated maximum totals of 8 inches. Heavy rainfall could lead
to areal, urban, and small stream flooding impacts, and cause new
minor flooding across the western Florida Peninsula and exacerbate
ongoing minor to isolated moderate flooding in northern Florida.

From Sunday onward, heavy rain and flood impacts could extend into
inland portions of the Southeast and into the southern and central
Appalachians and Piedmont as Fred interacts with a front in the
area.

WIND:  Tropical storm conditions are expected in portions of the
warning area across the Florida Keys on Saturday.

SURF:  Swells generated by Fred are expected to spread across
portions of the Bahamas and the northern coast of Cuba through
tonight. These swells could reach the Florida Keys and southern
Florida by early Saturday and increase along the west coast of
Florida Saturday night and Sunday.  Please consult products from
your local weather office for more details.

TORNADOES: A tornado or two may be possible starting Saturday 
afternoon across portions of central and southern Florida.
