Synopsis for the Gulf of America
451 AM EDT Fri Aug 28 2026
.SYNOPSIS...Weak high pressure will persist across the Gulf
waters through the next several days, supporting moderate or
lighter winds and slight seas. Winds will pulse to fresh to
locally strong with moderate seas off western Yucatan during the
evenings due to a diurnal surface trough moving west off the
peninsula each night. A frontal boundary will meander near the
northern Gulf waters during the next few days producing
scattered showers and isolated thunderstorms. Mariners can
expect gusty winds and higher seas associated with these storms.
