Synopsis for the Gulf of America

403 PM EDT Wed Aug 12 2026



.SYNOPSIS...The Atlantic ridge extends westward across Florida

into the Gulf region, and will change little through Sat before

weakening Sun. 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.
