Synopsis for the Gulf of America
1111 PM EDT Wed Aug 12 2026
.SYNOPSIS...The Atlantic ridge extends westward across Florida and
into the north-central 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.
