.SYNOPSIS...A ridge will dominate the Gulf region through Fri

producing a gentle to moderate anticyclonic flow and slight to

moderate seas. A cold front is forecast to enter the northwest

Gulf on Fri, and reach from southwest Florida to the central Bay

of Campeche by late Sat. Fresh to strong winds and moderate to

rough seas will follow the front, with gales expected over the

west-central Gulf by early Sat morning, and over the SW Gulf by

late Sat morning. Rough to very rough seas are expected with the 

strongest winds. Gale conditions are forecast to persist over the 

SW Gulf through Sun. Strong high pressure will follow the front

promoting fresh to strong NE to E winds mainly over the eastern 

half of the Gulf through Tue.
