Synopsis for the Gulf of America
1003 PM EST Fri Nov 21 2025
.SYNOPSIS...Relatively weak high pressure extends from the western
Atlantic westward over the eastern and central Gulf. The high
pressure will shift southeastward through Sun as a mostly
dry cold front moves across the northern Gulf waters. Fresh to
locally strong southeast to south winds are expected to develop
offshore of Texas and eastern Mexico Sun night into Mon afternoon
before becoming mostly fresh south to southwest winds across the
central and western Gulf through late Mon night as another weak
cold front moves off the Texas coast. The front will continue to
weaken as it reaches from the NE Gulf to the central Gulf by Wed.
A stronger cold front is forecast to move off the Texas coast late
Tue night, and reach from the near the western Florida panhandle
to the west-central Gulf by late Wed. Fresh northeast winds are
expected behind this front. Otherwise, moderate to occasionally
fresh northeast to east winds are expected each afternoon and
evening in the Bay of Campeche and north of the Yucatan Peninsula
as a diurnal trough develops and moves westward over the region.
Moderate or weaker winds and slight to moderate seas are expected
elsewhere through much of this weekend.
