Gentle to moderate winds prevail 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 low pressure over the Colorado River Valley will support moderate to occasionally fresh winds over the northern Gulf of California through the early part of the week. Elsewhere, a moderate pressure gradient will support mostly gentle to moderate winds across the offshore waters of Mexico. Long- period NW swell over the waters off Baja California Norte will start to subside Tue. Fresh to strong gap winds and building seas are expected across the Gulf of Tehuantepec toward the end of the week. ...OFFSHORE WATERS WITHIN 250 NM OF CENTRAL AMERICA, COLOMBIA, AND WITHIN 750 NM OF ECUADOR... Moderate to locally 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, with occasionally strong winds pulsing by mid week. 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... Fresh to near gale force winds, and rough seas, are over the far NW portion of the discussion waters due to the remnant low of Genevieve, centered just west of the area. Elsewhere over the discussion waters, gentle to moderate winds and moderate seas prevail. For the forecast, large northerly swell will bring rough seas over the waters off Baja California Norte north of 27N and east of 130W through the early part of the week before subsiding. New large southerly swell may build south of the Equator and west of 100W beginning Tue night.
