The strong NW winds will prevail into Mon as a surface trough along the coast of mainland Mexico deepens. West of Baja California seas of 6 to 10 ft prevail in decaying swell, with seas of 7 to 9 ft also occurring downwind of the Gulf of Tehuantepec. Seas are expected to build to 7-8 ft across central portions of the Gulf Sun night. Locally strong winds are expected this afternoon and evening along the coast of Cabo Corrientes.

Gentle to moderate winds prevail within an area of high pressure N of 24N, with decaying seas of up to 9 ft highest near 30N125W. Large NW swell will continue to move S-SE across the waters this weekend. The pressure gradient between the high to the north and lower pressure in the vicinity of the ITCZ is supporting fresh to locally strong NE trade winds north of the ITCZ to 23N, west of 115W.
