Synopsis for the Gulf of America

355 PM EDT Tue Mar 17 2026



.SYNOPSIS...A strong cold front is slowly moving southeastward 

across the Florida Straits and over the Yucatan Peninsula.

Moderate to fresh NE winds prevail north of 27N along with

moderate seas. South of 27N, fresh to strong N to NE winds are 

present with rough seas. Winds will continue to diminish, and 

seas will continue to subside from north to south through this 

afternoon and evening, except for the Yucatan Channel, where fresh

to strong N to NE winds will linger until Wed morning. In the 

wake of the front on Wed, high pressure will build across the 

region and prevail into the weekend.
