DISCUSSION AND OUTLOOK
----------------------
At 400 PM CDT (2100 UTC), the center of Subtropical Storm Alberto
was located near latitude 28.0 North, longitude 85.2 West.  The
storm is moving toward the north-northwest near 12 mph (19 km/h).  A
north-northwest motion with some decrease in forward speed is
expected tonight.  A north-northwestward to northward motion is
expected Monday through Wednesday.  On the forecast track, the
center of Alberto will move over the northern Gulf of Mexico tonight
and approach the northern Gulf Coast in the warning area on Monday.
Heavy rainfall and tropical storm conditions will likely reach the
northern Gulf Coast well before the arrival of the center of
Alberto.  Alberto is expected to move inland into the Tennessee
Valley on Tuesday and Wednesday.

Maximum sustained winds are near 50 mph (85 km/h) with higher gusts.
Little change in strength is forecast before Alberto reaches the
northern Gulf Coast.  Steady weakening is expected after landfall,
and Alberto is forecast to become a tropical depression Monday night
or Tuesday.

Winds of 40 mph extend outward up to 115 miles (185 km) from the
center.

The estimated minimum central pressure is 994 mb (29.36 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
20-25 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 northward within
the warning area tonight and continue through Monday.

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:  Isolated tornadoes are possible through tonight across
the central and northern Florida peninsula.

SURF:  Swells generated by Alberto will 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.
