* Suwannee River to the Mississippi/Alabama border

A Storm Surge Watch means there is a possibility of life-

risk, please see the National Weather Service Storm Surge
Watch/Warning Graphic, available at hurricanes.gov.

A Tropical Storm Warning means that tropical storm conditions are
expected somewhere within the warning area.

For storm information specific to your area, including possible
inland watches and warnings, please monitor products issued by your
local National Weather Service forecast office.


DISCUSSION AND OUTLOOK
----------------------
At 100 AM CDT (0600 UTC), the center of Subtropical Storm Alberto
was located near latitude 28.6 North, longitude 86.1 West. The
storm is moving toward the northwest near 9 mph (15 km/h). A north-
northwestward to northward motion is expected during the next few
days. On the forecast track, the center of Alberto will cross the
northern Gulf Coast in the warning area by this afternoon. The
weakening system is forecast to move well inland into the Tennessee
Valley on Tuesday and into the Ohio Valley and Great Lakes region on
Wednesday and Thursday.

Maximum sustained winds remain near 65 mph (100 km/h) with higher
gusts. Little change in strength is expected before Alberto reaches
the northern Gulf Coast later today. Steady weakening is forecast
after landfall, and Alberto will likely become a subtropical
depression tonight or early Tuesday and degenerate into a remnant
low by Tuesday afternoon.

Winds of 40 mph extend outward up to 115 miles (185 km) from the
center. NOAA buoy 42039 in the northeastern Gulf of Mexico
recently reported a sustained wind of 49 mph (79 km/h) with a gust
to 61 mph (98 km/h).

The estimated minimum central pressure based on aircraft and
buoy observations is 990 mb (29.23 inches).


HAZARDS AFFECTING LAND
----------------------
RAINFALL: Alberto is expected to produce the following rain
accumulations through Tuesday:

Central Cuba...Additional 5 to 10 inches, isolated storm-totals of
20 to 25 inches.

The Florida panhandle into much of Alabama and western Georgia...4
to 8 inches, isolated 12 inches.

The Florida Keys and south Florida...Additional 3 to 6 inches,
isolated storm totals of 10 inches.

Rest of the Florida peninsula...1 to 4 inches.

Rest of the Southeast and Tennessee Valley into the lower mid
Atlantic from Tennessee east through the Carolinas...2 to 6 inches.

Rains in Cuba could produce life-threatening flash floods and
mudslides. Flooding and flash flooding are possible in the
southeast United States, including Florida.

WIND: Tropical storm conditions will spread across the warning area
throughout the day.

STORM SURGE: The combination of 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...

Crystal River to Navarre Florida...2 to 4 ft

The deepest water will occur along the immediate coast. 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.

TORNADOES: A couple of brief tornadoes are possible today across
much of Florida, central and southern Georgia, southern South
Carolina, and southeastern Alabama.

SURF: Swells generated by Alberto will continue to affect the
eastern and northern Gulf Coast through Tuesday. These swells are
likely to cause life-threatening surf and rip current conditions.
For more information, consult products from your local weather
office.
