Synopsis for the Gulf of America
421 AM EDT Sun May 18 2025
.SYNOPSIS...The pressure gradient between high pressure over the
eastern Gulf and relatively lower pressure in Texas and eastern
Mexico will maintain moderate to fresh SE winds and moderate
seas across the western Gulf through Tue. Pulsing fresh to
strong E winds are likely each afternoon and evening through Tue
night, north of the Yucatan Peninsula as a trough develops daily
and drifts westward. Smoke from agricultural fires in
southeastern Mexico will sustain hazy conditions at the
west-central and southwestern Gulf most likely through the
period.
