Synopsis for the Gulf of America

912 AM EDT Mon Aug 17 2026



.SYNOPSIS...High pressure will prevail across the Gulf waters

through the week. A weak pressure gradient will support mostly

gentle to moderate winds across much of the basin. A diurnally

induced surface trough will generate fresh to occasionally

strong winds N of the Yucatan peninsula early each evening.

These winds will spread westward away from the Yucatan at night

as the trough migrates into the SW Gulf. Slight to moderate seas

are expected through the forecast period.
