...Gulf of Mexico...

A ridge will dominate the Gulf region over the next several days producing mainly a moderate to locally fresh wind flow, except off the W coast of the Yucatan Peninsula where late evening local effects will keep brief periods of NE winds to 20 kt with seas in the 3 to 5 ft range.

...Caribbean Sea and tropical N Atlantic from 07n to 19n between 55w and 64w...

A cold front extending from eastern Cuba to the Gulf of Honduras is allowing for a relaxed pressure gradient in the south-central Caribbean. However, fresh to strong winds are expected to pulse at night within 90 nm off the coast of Colombia through Fri night. The cold front will drift se today and tonight while gradually dissipating. Gentle to moderate winds will dominate across the remainder of the basin through sun.

This front will remain nearly stationary today and tonight. Then, a reinforcing cold front will merge with the stationary front on Fri, and the merged front will extends from 27n65w to the Turks and Caicos Islands and eastern Cuba by Fri night. Swell generated by these fronts will dominate the waters E of the Bahamas through the upcoming weekend.
