Moderate to fresh winds are over the northern Gulf of California. Gentle to moderate winds prevail elsewhere across the region. Moderate seas dominate the open waters off Mexico, with slight seas in the Gulf of California. For the forecast, the pressure gradient between high pressure west of the area and lowering pressure over the Colorado River Valley will support fresh SW winds and building seas over the northern Gulf of California through the early part of next week. Elsewhere, a moderate pressure gradient will support mostly gentle to moderate NW winds across the offshore waters of Mexico. Long- period NW swell will move into the waters off Baja California Norte tonight then start to subside Tue. Looking ahead, expect fresh to strong gap winds and building seas across the Gulf of Tehuantepec Thu and Fri. ...OFFSHORE WATERS WITHIN 250 NM OF CENTRAL AMERICA, COLOMBIA, AND WITHIN 750 NM OF ECUADOR... Fresh winds and moderate seas prevail over and downstream the Gulf of Papagayo. Gentle to moderate winds are found between the Galapagos Islands and Ecuador. Light to gentle winds and moderate seas are noted elsewhere. For the forecast, moderate to fresh winds will pulse across the Papagayo region tonight, and again by mid week with rough seas. Moderate or weaker winds and moderate seas in SW swell are expected across the remainder of the waters through the period. ...REMAINDER OF THE AREA... Please refer to the Special Features section for information on Post-Tropical Storm Genevieve. For waters not impacted by Genevieve, high pressure is centered just northwest of the area. Gentle to moderate winds and moderate seas prevail over the remainder of the discussion waters. Large northerly swell off California is likely to push southward into the waters off Baja California Norte north of 27N and east of 130W into early next week. New large southerly swell may build south of the Equator and west of 100W beginning Tue night.
