Synopsis for the Gulf of America

929 AM EDT Sun Aug 16 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.
