Based on 0000 UTC surface analysis and satellite imagery through 0200 UTC. ...INTERTROPICAL CONVERGENCE ZONE/MONSOON TROUGH... The monsoon trough extends from 10N85W to 07N96W. The ITCZ extends from 07N96W to 10N120W to beyond 07N140W. Scattered moderate convection is noted from 05N to 10N between 101W and 137W. ...OFFSHORE WATERS WITHIN 250 NM OF MEXICO...

Gentle to moderate winds prevail west of the Baja California peninsula extending southward to the Revillagigedo Islands, as well as over the southern Gulf of California. Light to gentle winds are found elsewhere. Seas are in the 8-10 ft range west of the Baja California peninsula extending southward to the Revillagigedo Islands. Seas of 6-8 ft are over the Gulf of Tehuantepec. Elsewhere, seas are in the 4-6 ft range over the open waters off Mexico. In the Gulf of California, seas are 3 ft or less. For the forecast, moderate to fresh winds will prevail from 17N to 20N into the early part of the week, with locally strong speeds near Cabo Corrientes. Similar winds will prevail across most of the Gulf of California into mid-week. Large NW swell will prevail offshore the Baja California peninsula and southward to the Revillagigedo Islands through Mon night before starting to subside. New NW swell may arrive next weekend. Fresh to near gale-force N gap winds can be expected over the Gulf of Tehuantepec through early Mon before diminishing.
