Synopsis for the Gulf of America

410 AM EDT Tue Aug 11 2026



.SYNOPSIS...A surface ridge extends from the Bermuda High

westward across the northern Gulf, and will dominate the general

wind flow pattern across basin through Sat night. Gentle to

moderate E to SE winds will prevail across the basin, with the 

exception of 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.
