Synopsis for the Gulf of America

1112 PM EDT Mon Mar 16 2026



.SYNOPSIS...A strong cold front extends southwestward from 

just south of Tampa, Florida to near Coatzacoalcos, Mexico.

Northerly winds at fresh to strong exist across the northern 

Gulf, while strong to near gale-force dominate the west-central 

and central Gulf, and the eastern Bay Campeche. At the western Bay

of Campeche, especially off Veracruz, near-gale to gale-force NW 

to N winds are present. These trends will continue until midnight 

tonight, then winds across the locations mentioned above should 

begin to subside. For the southeastern Gulf by midnight, moderate 

southerly winds will shift to the NW and become fresh to locally 

strong as the front passes through the area on its way to the 

Great Bahama Bank and northwestern Caribbean. Rough to very rough 

seas behind the front will gradually subside from north to south 

by early Tue morning. In the wake of the front, high pressure will

build across the region and prevail into the weekend.
