DISCUSSION AND OUTLOOK
----------------------
At 1100 AM EDT (1500 UTC), the center of Tropical Storm Fred was
located near latitude 26.1 North, longitude 84.9 West. Fred is
moving toward the north-northwest near 12 mph (19 km/h), and this 
motion should continue through tonight.  A turn toward the north is 
expected on Monday.  On the forecast track, the center of Fred 
should move across the eastern and northern Gulf of Mexico through 
Monday, then make landfall in the western Florida Panhandle Monday 
afternoon or Monday night.

Reports from an Air Force Reserve Hurricane Hunter aircraft 
indicate that maximum sustained winds are near 40 mph (65 km/h) with 
higher gusts.  Gradual strengthening is expected until landfall, 
while Fred is expected to weaken quickly after landfall.

Tropical-storm-force winds extend outward up to 80 miles (130 km)
from the center.

The minimum central pressure reported by the Hurricane Hunter 
aircraft is 1008 mb (29.77 inches).


HAZARDS AFFECTING LAND
----------------------
Key messages for the Remnants of Fred can be found in the Tropical
Cyclone Discussion under AWIPS header MIATCDAT1, WMO header WTNT41
KNHC and on the web at
www.hurricanes.gov/graphics_at1.shtml?key_messages.

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

Through Monday...

Florida Keys and southern Florida... 3 to 5 inches of rain is 
anticipated.

Through Tuesday...

The Florida Big Bend and Panhandle... 4 to 8 inches with isolated
maximum storm totals of 12 inches are expected.

South-Central and Southeast Alabama through Georgia and the Western
Carolinas... 3 to 6 inches with isolated maximum storm totals of 9
inches are expected due to the combination of Fred and a preceding
frontal boundary.

Heavy rainfall across portions of Florida, southern Alabama,
portions of Georgia, and the western Carolinas could lead to areal,
urban, small stream and river flooding impacts.

STORM SURGE:  The combination of a dangerous storm surge and the
tide will cause normally dry areas near the coast to be flooded by
rising waters moving inland from the shoreline.  The water could
reach the following heights above ground somewhere in the indicated
areas if the peak surge occurs at the time of high tide...

Indian Pass to Steinhatchee River...2-4 ft
AL/FL border to Indian Pass including Pensacola Bay, Choctawhatchee
Bay and Saint Andrew Bay... 1-3 ft
Steinhatchee River to Chassahowitzka, FL...1-3 ft

The deepest water will occur along the immediate coast near and to
the east of the landfall location, where the surge will be
accompanied by large waves.  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 forecast office.

WIND:  Tropical storm conditions are expected in the tropical storm
warning area beginning on Monday.

SURF:  Swells generated by Fred are expected to reach the coast of
Mississippi, Alabama and the Florida Panhandle on Monday.  Please
consult products from your local weather office for more details.

TORNADOES:  A tornado or two will be possible today into early
Monday, near the west coast of Florida and the coastal Florida
Panhandle.
