Synopsis for the Gulf of America

1111 PM EDT Fri Oct 16 2026



.SYNOPSIS...A cold front extends from Mobile Bay to Tampico,

Mexico. Fresh to strong N winds and building seas follow the 

front, which is forecast to reach from near Tampa Bay, Florida to

the central Bay of Campeche by early Sat morning, and from the 

Straits of Florida and the SE Gulf to the eastern Bay of Campeche 

by early Sun morning. The front will be just SE of the area on Mon

where it will gradually dissipate. Strong gale force winds and 

rough to very rough seas are expected in the wake of the front 

over the west-central Gulf tonight, and over the southwest Gulf by

Sat morning. Frequent gusts to gale-force are forecast elsewhere 

NW of the front tonight into Sat morning. Looking ahead, strong 

high pressure will build over the lower Mississippi Valley behind 

the front, promoting fresh to strong NE to E winds mainly over 

the eastern half of the Gulf into mid week.
