Synopsis for the Gulf of America
443 AM EDT Sun Jul 20 2025

.SYNOPSIS...Relatively weak high pressure will prevail across
the basin through the middle of the next week producing gentle
to moderate winds along with slight to moderate seas. Fresh to
locally strong northeast to east winds will pulse along the
Yucatan Peninsula each afternoon and evening well into the
upcoming week as a trough develops inland daily and shifts
westward over the Bay of Campeche at night. Looking ahead, winds
may increase to fresh speeds across the NE Gulf by Thu as broad
low pressure moves across the southeastern U.S. before possibly
moving from E to W across the northern Gulf. Widespread showers
and thunderstorms are expected over most of the eastern and north-
central Gulf waters starting Tue.
