Synopsis for the Gulf of America

921 PM EDT Tue Sep 8 2026



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

through the weekend, 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.
