Synopsis for the Gulf of America
337 AM EST Tue Nov 25 2025
.SYNOPSIS...A weak cold front is along the Texas coast and
is forecast to drift into the NW Gulf today. The moderate to
fresh southerly winds will decrease to gentle to moderate later
today as high pressure off New England departs eastward. A
stronger reinforcing cold front will overtake the aforementioned
weak front early Wed, then move into the NW Gulf waters. 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.
