Synopsis for the Gulf of America

527 AM EDT Sat Aug 15 2026



.SYNOPSIS...A high pressure center will remain over the north-

central Gulf this weekend, then moves SE while weakening some by

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 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. Looking

ahead, by midweek next week winds may increase to fresh speeds

over the NW and west-central Gulf as the pressure gradient

tightens between the high pressure and lower pressures over

north-central Mexico.
