Synopsis for the Gulf of America

313 AM EDT Tue Apr 28 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 Wed morning. 

Elsewhere, a diurnal trough will pulse fresh to strong winds

off the Yucatan Peninsula this evening, then at mostly fresh

speeds through Fri night. A weak cold front will brush the

northern portion of the NE Gulf Thu through early Fri. A

rather strong spring time cold front should emerge off the

Texas coast late Fri night, then reach from northern Florida

to the Bay of Campeche by late on Sat. This front will be

followed by fresh to strong north to northeast winds, with

near gale winds possibly over the west-central and SW Gulf 

sections. Seas are presently forecast to build to 12 ft with these 

winds Sat and Sat night.
