DISCUSSION AND OUTLOOK
At 800 AM EDT (1200 UTC), the remnants of Fred were located near
latitude 25.3 North, longitude 84.6 West. While the center has
jogged northward during the past few hours, the remnants are moving
generally toward the north-northwest near 8 mph (13 km/h). This
general motion is expected to continue through tonight, with a turn
toward the north expected on Monday. On the forecast track, the
system will cross the southeastern Gulf of Mexico today, cross the
east-central and northern Gulf of Mexico tonight and Monday, and
move inland along the northern Gulf coast Monday night or early
Maximum sustained winds are near 40 mph (65 km/h) with higher
gusts. Fred is expected to re-develop into a tropical storm later
today, with gradual strengthening expected while it moves over the
Gulf of Mexico until it makes landfall.
* Formation chance through 48 hours...high...90 percent.
* Formation chance through 5 days...high...90 percent.
Tropical-storm-force winds extend outward up to 115 miles (185 km)
from the center.

The system is expected to produce the following rainfall amounts:
Florida Keys and southern Florida... 3 to 5 inches with isolated
storm totals of 8 inches are anticipated.
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

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...
Mouth of the Pearl River, LA to Suwannee River, FL including Mobile
Bay, Pensacola Bay, Choctawhatchee Bay and Saint Andrew Bay... 1-3
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 possible within the watch area
by late Monday night or Tuesday morning.
SURF: Swells generated by Fred or its remnants are expected to
spread across the Florida Keys later this morning and reach the
coast of Mississippi, Alabama and the Florida Panhandle on Monday.
Please consult products from your local weather office for more
TORNADOES: A tornado or two will be possible today into early
Monday, near the west coast of Florida and the coastal Florida
