Synopsis for the Gulf of America

935 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 support 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 strong cold front will 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

possible over the west-central and SW Gulf sections. Seas are 

forecast to build to 12 ft with these winds Sat and Sat night.
