Synopsis for the Gulf of America

310 PM 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 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.
