Synopsis for the Gulf of America

933 AM EDT Fri Aug 21 2026



.SYNOPSIS...Relatively weak high pressure centered over the

central Gulf will prevail through early next week. A weak

pressure pattern will support mostly gentle to moderate winds

and slight to locally moderate seas across much of the basin. A

surface trough will generate fresh to locally strong winds north

and west of the Yucatan Peninsula in the early evenings. These

winds will spread westward away from the peninsula at night as

the trough migrates into the SW Gulf.
