Synopsis for the Gulf of America
1003 PM EST Thu Dec 11 2025
.SYNOPSIS...A cold front extending from the Florida Keys to near
24.5N88W then stationary to just offshore of S Texas will stall
overnight and dissipate. Elsewhere, moderate to occasionally
fresh E to NE winds will prevail in the eastern Bay of Campeche
and offshore of the Yucatan Peninsula each night through Sat.
Otherwise, moderate or weaker winds and slight seas are expected
over the remainder of the basin through Sat. Looking ahead, the
next cold front is expected to enter the northern Gulf on Sun
morning, bringing increasing winds and building seas behind the
front. The front is expected to reach the southern Gulf along 23N
by Mon morning and move south of the basin late Mon night.
