Synopsis for the Gulf of Mexico

.SYNOPSIS...Strong high pressure over the Ohio Valley is
supporting strong north to northeast winds over the southeastern
Gulf.  Winds and seas will gradually diminish today as the high 
shifts northeastward. Strong northeast to east winds will 
continue across the eastern Gulf and the Straits of Florida 
through Fri night as the cold front stalls. A north to south 
aligned surface trough will develop across the central Gulf Fri,
with strong east winds covering the Gulf to the east of the 
trough. Low pressure is expected to develop from the trough over 
NE Gulf by early Sat and move across northern Florida this 
weekend. Gale force winds are possible in the NE Gulf late Sat 
through Sat night.
