A trough is analyzed from 11N134W to 04N138W. Scattered moderate convection from 04N to 06N between 90W and 92W, from 04N to 09N between 122W and 130W, and also from 05N to 09N between 134W and 138W. OFFSHORE WATERS WITHIN 250 NM OF MEXICO... High pressure of 1021 mb centered near 24N121W will weaken and drift SE through today and tonight, as a cold front approaches Baja California Norte while also weakening. Ahead of the front, locally strong SW winds will impact the northern Gulf of California into the early morning hours today. Peak seas in this area will reach 4 to 6 ft. Low pressure to the S of Tijuana Mexico will have a trailing trough or cold front that will cross Baja California during the upcoming night through Wed. Strong to near gale force W-NW winds will follow this trough/front Wed in the offshore waters of Baja California, and also in the northern Gulf of California Wed and Wed evening. Strong N gap winds will persist overnight in the Gulf of Tehuantepec through the morning due to high pressure over the Gulf of Mexico, however seas should remain just below 8 ft. This high will weaken and move east by the afternoon. Looking ahead, another round of strong northerly gap winds in the Gulf of Tehuantepec will be possible late in the week into the weekend. Elsewhere across the Mexican offshore waters, mainly gentle to moderate winds and SW swell of 5 ft or less will dominate through mid week, with winds strengthening slightly by the end of the week into the weekend. OFFSHORE WATERS WITHIN 250 NM OF CENTRAL AMERICA, COLOMBIA, AND WITHIN 750 NM OF ECUADOR... High pressure over the Caribbean will generally maintain strong NE to E gap winds over the Gulf of Papagayo region through at least Sat night. Fresh N winds will continue across the Gulf of Panama and downstream to 05N into Thu, with locally strong winds likely during the evenings. A moderate S to SW swell currently impacting the waters will subside by later today. REMAINDER OF THE AREA... High pressure of 1021 mb centered near 24N121W is contributing to moderate to fresh NE trades N of the ITCZ. Peak seas reach up to 8 ft across the tradewind belt. Little change is expected during the next several days. Low pressure will skirt along 30N/31N toward Baja California Norte through the upcoming night and Wed. Strong to near gale force W-NW winds behind an attendant trough or cold front are forecast generally N of 25N and E of 133W into Wed. Peak seas should range from 9-12 ft.
