Synopsis for the Gulf of America
422 AM EDT Sun Apr 20 2025

.SYNOPSIS...A tight pressure gradient between high pressure
centered offshore the SE United States and low pressure over
Texas will lead to fresh to strong SE winds over much of the
Gulf early this week, along with moderate to rough seas.
Conditions will start to improve Tue as the gradient weakens, but
pulses of strong SE winds will depart the NW Yucatan Peninsula
nightly as a diurnal trough moves into the waters.
