Synopsis for the Gulf of America

426 AM EDT Wed Aug 12 2026



.SYNOPSIS...The western Atlantic ridge extends westward into the

NE Gulf, 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.
