Synopsis for the Gulf of America

1111 PM EDT Thu Aug 27 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.
