Synopsis for the Gulf of America

331 AM EDT Sun Apr 12 2026



.SYNOPSIS...High pressure centered off the Carolinas will begin to 

slide eastward into the western Atlantic starting this evening.

A ridge will extend southwestward from the high to the north- 

central Gulf through the forecast period. The related gradient

will maintain moderate to fresh east winds across the basin through 

Wed. Afterward, the high pressure will be weakening allowing for 

winds over the area to diminish to gentle to moderate speeds. 

Pulsing fresh to strong east winds will surge through the Straits of 

Florida and into the southeastern Gulf starting today. Seas across 

the basin will be at a mostly moderate state, except reaching a 

rough state, at times, in the Straits of Florida beginning on Mon. 

Seas subside around midweek.
