Synopsis for the Gulf of America
329 AM EDT Tue Sep 8 2026
.SYNOPSIS...Weak high pressure will persist across the Gulf
basin through the period, producing a weak pressure gradient.
This will support mostly light to gentle winds and slight seas
over much of the waters. Winds will pulse to fresh with moderate
seas off the western Yucatan Peninsula during the evenings due
to a diurnal surface trough moving westward from the peninsula
each night.
