Synopsis for the Gulf of America
1018 AM EDT Fri Aug 28 2026
.SYNOPSIS...Weak high pressure will persist across the Gulf
waters into 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.
