Synopsis for the Gulf of America

448 AM EDT Tue Mar 17 2026



Updated to add thunderstorms in the Florida Straits



.SYNOPSIS...A strong cold front is pushing southeastward across

the Florida Straits and over the Yucatan Peninsula this morning.

Northerly winds, mainly fresh exist across the Gulf north of

25N, while fresh to strong dominate south of 25N. At the western

Bay of Campeche, especially off Veracruz, these winds are

peaking at near gale- force. These trends will continue through

this morning, then gradually decrease this afternoon and

evening, except for the southeastern Gulf, where moderate to

strong N to NE winds will linger until late this evening. Rough

to very rough seas behind the front will gradually subside from

north to south today through this evening. In the wake of the

front on Wed, high pressure will build across the region and

prevail into the weekend.
