Synopsis for the Gulf of America

310 PM EDT Mon Apr 27 2026



.SYNOPSIS...The pressure gradient between weak high pressure

over the eastern Gulf and a trough that extends along the coast

of Mexico from Tampico to Veracruz will produce moderate to

fresh southeast winds and moderate seas over the western half of

the Gulf, and gentle to moderate winds with slight to moderate

seas over the eastern part of the basin through early Wed.

Elsewhere, a diurnal trough will pulse moderate to fresh winds

off the Yucatan Peninsula during the evenings through Fri night.

A cold front will enter the northern Gulf Wed night into Thu and

reach from South Florida to central Texas by late Fri.
