Synopsis for the Gulf of America
1103 PM EDT Thu Aug 20 2026

.SYNOPSIS...Relatively weak high pressure centered over the
central Gulf will prevail over the basin 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.
