Synopsis for the Gulf of America
438 AM EDT Thu Aug 13 2026

.SYNOPSIS...The Atlantic ridge extends westward across south Florida
and into the north-central Gulf, and will change little through 
Sat before weakening Sun and Mon. This pattern will produce 
mostly gentle to moderate E to SE winds across the basin, with 
pulses of fresh winds occurring north and west of the Yucatan 
Peninsula and into the Bay of Campeche each evening and night, as 
a diurnal surface trough migrates from the Yucatan Peninsula 
westward across the SW Gulf. Slight to moderate seas are expected 
through the forecast period.
