   GMZ001-200800-  Synopsis for the Gulf of America  436 PM EDT Wed Aug 19 2026      .SYNOPSIS...Relatively weak high pressure centered over the  central Gulf will prevail over the basin through the forecast  period. A weak pressure pattern will support mostly gentle to  moderate winds and slight to locally moderate seas across much of  the basin. A diurnally induced 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.    $$
