DISCUSSION AND OUTLOOK

At 800 PM EDT (0000 UTC), the center of Tropical Depression Fred 
was located near latitude 22.5 North, longitude 80.2 West. The

west-northwestward motion is expected to begin overnight.  A turn
toward the northwest is expected on Saturday, and this general
motion should continue through early Monday.  On the forecast track,
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 pass near or west of the west coast of the Florida
peninsula Saturday night and Sunday.

Maximum sustained winds are near 35 mph (55 km/h) with higher
gusts. Little change in strength is expected tonight.  After that,
slow strengthening is forecast, and Fred could become a tropical
storm again on Saturday.

The estimated minimum central pressure is 1013 mb (29.92 inches).

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.

Today 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, and potentially worsen
ongoing minor to isolated moderate river flooding over 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. Tropical storm
conditions are possible in the watch area in Florida beginning
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: There will be a risk of isolated tornadoes beginning
Saturday afternoon over parts of central and south Florida.
