Synopsis for the Gulf of America
917 PM EST Mon Nov 24 2025
.SYNOPSIS...A cold front is approaching the NW Gulf waters, along
with strong showers and thunderstorms. A warm front is lifting
northward over the NE Gulf ahead of the aforementioned cold front.
Expect fresh southerly flow off the Texas coast tonight supported
by the gradient between low pressure over northeast Mexico and
high pressure off the Carolinas. These winds will diminish Tue
ahead of the aforementioned cold front. A stronger reinforcing
cold front will overtake the frontal boundary early Wed, then move
into the NW Gulf. The cold front will then sweep to the southeast
of the basin by Thu night into Fri, followed by fresh to strong
northeast winds and building seas into the weekend. Scattered
showers and thunderstorms may accompany the frontal boundary.
