Synopsis for the Gulf of America
950 AM EDT Thu Aug 27 2026
.SYNOPSIS...Weak high pressure will persist across the Gulf
waters through early next week, supporting moderate or weaker
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.
