SYNOPSIS
A ridge will continue to dominate the Gulf waters this week. Its associated pressure gradient will maintain moderate to fresh east to southeast winds over the basin for the next few days. East winds will pulse to strong speeds north of the Yucatan peninsula and over the Bay of Campeche at tonight through Fri night in association with a diurnal trough. Moderate to fresh east winds and moderate seas are expected over the Straits of Florida through Thu night. Elsewhere, winds will begin to diminish Fri and into the weekend. Looking ahead, a weak cold front may reach the NE Gulf Sat night.
