Synopsis for the Gulf of America
1006 AM EST Sat Dec 13 2025
.SYNOPSIS...Weak high pressure located over north Florida and
the adjacent Atlantic will slide northeastward and into the NW
Atlantic through tonight to produce moderate to occasionally
fresh E to SE winds across the S and W Gulf. Otherwise, moderate
or weaker winds and slight seas are expected over the remainder of
the basin through Sat. The next cold front is expected to enter
the northern Gulf on Sun morning, bringing strong N to NE winds
and building seas behind the front. The front is expected to reach
the south-central Gulf along 24N by Mon morning, and move south
of the basin Mon night.
