Synopsis for the Gulf of America

1020 PM EDT Fri Aug 28 2026



.SYNOPSIS...Weak high pressure will persist across the Gulf

waters through early next week, supporting moderate or lighter

winds and slight seas. Winds will pulse to fresh with moderate

seas off western Yucatan during the evenings due to a diurnal

surface trough moving west off the peninsula each night. A

nearly-stationary front will meander near the northern Gulf 

waters during the next few days producing a few thunderstorms. 

Mariners can expect gusty winds and higher seas associated with 

the stronger thunderstorms.
