Synopsis for the Gulf of America
405 PM EDT Thu Apr 17 2025

.SYNOPSIS...Fresh to strong NE winds will pulse offshore of the
Yucatan Peninsula and in the eastern Bay of Campeche through
this weekend as a trough develops daily and moves westward.
Elsewhere, fresh to locally strong SE winds will develop west of
90W tonight as a low pressure system strengthens in the central
United States. By Fri, fresh to locally strong SE winds are
expected across much of the basin, including through the Florida
Straits, as the pressure gradient strengthens between the
aforementioned low and building high pressure over the western
Atlantic. Seas will slowly build through this weekend, with
rough seas possible near the strong winds by early Sat. Looking
ahead, winds and seas will slowly diminish next week.
