* Cuban province of Pinar del Rio

A Tropical Storm Watch means that tropical storm conditions are
possible within the watch area, in this case within the next 24
hours.

Interests along the central and eastern U.S. Gulf Coast should
monitor the progress of Alberto. Tropical storm and storm surge
watches could be required for portions of this area later today or
tonight.

For storm information specific to your area, please monitor
products issued by your national meteorological service.


DISCUSSION AND OUTLOOK
----------------------
At 1000 AM CDT (1500 UTC), the center of Subtropical Storm Alberto
was located near latitude 19.7 North, longitude 86.8 West. The storm
is moving toward the north-northeast near 6 mph (9 km/h). A general
slow motion toward the north is expected through the weekend,
followed by a northwest turn by Monday. On the foreast track,
Alberto is expected to pass near the eastern coast of the Yucatan
peninsula tonight, be near the western tip of Cuba Saturday morning,
emerge over the southeastern Gulf of Mexico by Saturday night, and
approach the north-central Gulf Coast on Monday.

Maximum sustained winds are near 40 mph (65 km/h) with higher gusts.
Gradual strengthening is forecast for the next 72 hours.

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

The estimated minimum central pressure is 1005 mb (29.68 inches).


HAZARDS AFFECTING LAND
----------------------
RAINFALL: Alberto is expected to produce total rain accumulations
of 10 to 15 inches with isolated totals of 25 inches across the
northeastern portions of the Yucatan Peninsula and western Cuba.
These rains could produce life-threatening flash floods and
mudslides. Rainfall accmumulations of 4 to 8 inches with maximum
amounts of 12 inches are possible across the Florida Keys and
southern and southwestern Florida. Heavy rain will likely begin
to affect the central Gulf Coast region and the southeastern Untied
States later this weekend and continue into early next week.
Flooding potential will increase across this region early next
week as Alberto is forecast to slow down after it moves inland.

WIND: Tropical storm conditions are possible within the watch
area through Saturday.

SURF: Swells generated by Alberto are affecting portions of
the coast of eastern Yucatan Peninsula and western Cuba. These
swells are likely to cause life-threatening surf and rip current
conditions. Hazardous surf conditions are likely to develop along
much of the central and eastern U.S. Gulf Coast this weekend. For
more information, consult products from your local weather office.

If they get that strong at all. Look at the wind speed probability map.

It looks like a Mobile/Pensacola landfall as a strong near-hurricane strength subtropical storm.

It has the potential to create cat 1 or 2 wind and the rain dump alone will create massive flooding. Not to mention the timing...

8. 80 or above is necessary to feed a storm, b-pressure is average, movement at 6 miles per hour

The major metrics indicate a possible stall and strengthening. Not sayin a 5 or anything...but a cat 1 seems a little more like hoping...

18. According to the map you posted eariler as well as the data Im looking at its above 80

This is gonna be a devastating event, not matter what the cat...but I do think its gonna be a cat. The biggest problem for locals is that the ground is already rain saturated. So, it can not handle storm surge and rain. Some models are predicting a new orleans landfall with 96-100 mph winds.....it will definitely be a thang....
