Synopsis for the Gulf of America
311 PM EST Fri Dec 12 2025

.SYNOPSIS...Weak high pressure located over north Florida will 
slide eastward and into the Atlantic through Sat 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 increasing winds and building seas behind the front. The 
front is expected to reach the south-central Gulf along 24N/25N by
Mon morning, and move south of the basin Mon night.
