Synopsis for the Gulf of Mexico

.SYNOPSIS...A 1012 mb extratropical low in the central Gulf is
accompanied by gale force N winds. The low should deepen and 
steadily move northeastward and reach the Florida peninsula on 
Tue. Gale force N winds are anticipated to continue in the low's 
W semicircle, but are likely to only cover a limited region. As 
the low crosses Florida, it will drag a cold front across the SE 
Gulf by Tue night. Strong to near gale NW winds behind the front 
will quickly diminish on Wed. Conditions across the Gulf will be 
quiescent on Thu. On Fri and Sat, S return flow in the W Gulf 
will reach fresh to strong.
