Synopsis for the Gulf of America
1119 PM EDT Wed Aug 27 2025

.SYNOPSIS...A frontal boundary will linger over the northern
Gulf through tonight before lifting NW of the area by Thu. Then,
high pressure will dominate the basin the remainder of the week
into the weekend. Under this weather pattern, mainly gentle to
moderate winds will prevail across the basin, except for
moderate to fresh NE to E winds over the S-central and SW Gulf
nightly as a diurnal trough develops over the Yucatan Peninsula
and moves westward at night. Slight to locally moderate seas are
forecast across the Gulf waters through the upcoming weekend.
