Synopsis for the Gulf of America
331 AM EDT Fri Apr 17 2026
.SYNOPSIS...A ridge across the northern Gulf will remain in
place and slowly weaken through Sat, maintaining a weak pressure
gradient across the basin. This pressure gradient will support
gentle to moderate E to SE winds across most of the basin through
Sat. The exception will be off the Yucatan Peninsula, where a
daily trough will result in a locally tighter pressure gradient to
support a pulsing of fresh to strong winds during the evenings.
Fresh to strong N to NE winds and building seas will follow a cold
front moving across the northern Gulf Sat night through the early
part of the week. The front will stall from the Florida Straits
to south Texas by late Mon then dissipate through Tue.
