...SPECIAL FEATURES...
Subtropical Storm Alberto centered near 21.6N 84.9W at 26/1500
UTC moving north at 9 kt. Estimated minimum central pressure is
1005 mb. Maximum sustained wind speed is 35 kt with gusts to 45
kt. Alberto is interacting with an upper trough, supporting
widespread showers and thunderstorms over the northwest Caribbean,
western and central Cuba and the southeast Gulf of Mexico through
South Florida. The stronger winds on the northeast side of the
center of Alberto are commencing in the southeast Gulf north of
western Cuba, allowing seas to build. The forecast calls for
gradual development as Alberto moves northward across the central
Gulf of Mexico late Mon, making landfall along the north central
Gulf coast by early Tue. See latest NHC forecast/advisory under
AWIPS/WMO headers MIATCMAT1/WTNT21 KNHC for more details.

Storm2k blog reports analysis that pressure at the center is dropping below 1000 (currently 997) which is ONE major factor in this storm developing into a hurricane. They are also reporting that this is happening early in the systems development, which means the chance to strengthen quickly into sunday morning is likely. Most models agree that people from Destin to Tampa should monitor weather regularly-especially those from Destin to Pensacola. Otherwise, you could wake up sunday morning to a hurricane or hurricane warning. It is currently in the gulf and coming upon warmer water temps -average in its path 83.
People in the gulf coast should be aware that the rain totals will be extremely high and that already drenched soil will mean flooding and flash flood. Landfall could happen at overnight/early in the morning. KEEP IN MIND, most people are killed by RISING WATER and NOT WIND. If you live in the area, you should take this system very seriously.
The blog below is a solid resource for people to get early warning and analysis.
