Synopsis for the Gulf of America
325 AM EST Wed Dec 10 2025

.SYNOPSIS...A ridge stretches SW from the southeastern United
States to the western Gulf. Moderate to locally fresh west to
northwest winds and moderate seas will develop in the NE Gulf
late this afternoon as a dry cold front moves across the southern
Unites States. The front will cross the northern Gulf waters
tonight into early Thu, with winds turning to the northwest to
north in direction behind the front. Otherwise, moderate or
weaker winds and slight seas are expected over the remainder of
the Gulf into early Sun as weak high pressure prevails over the
basin. Later on Sun and Sun night, it presently appears that
another cold front may move across the basin, followed by stronger
winds.
