Synopsis for the Gulf of America

1113 PM EDT Thu Aug 13 2026



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

and into the Gulf region, 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 surface

trough migrates from the Yucatan Peninsula westward across the SW

Gulf. Slight to moderate seas are expected through the forecast 

period.
