The monsoon trough extends from 09N84W to 11N113W to 08N122W. The ITCZ continues from 08N122W to 06N136W to 08N140W. Scattered moderate isolated strong convection is noted from 10N to 16N between 100W and 110W. ...OFFSHORE WATERS WITHIN 250 NM OF MEXICO... Please see above for more on an upcoming Gulf of Tehuantepec gale-force gap wind event. Fresh N winds prevail over the northern Gulf of California. Gentle to moderate winds prevail off the coast of southern and SW Mexico. Light to gentle winds are noted elsewhere. Seas are in the 8-10 ft range in NW swell off Baja California Norte, 7-9 ft off Baja California Sur, and 4-6 ft over the remainder of the open waters off Mexico. Over the Gulf of California, seas are in the 2-3 ft range, except 4-6 ft in the northern Gulf. For the forecast, NW swell over the far offshore waters off Baja California Norte will reach the Revillagigedo Islands by late today. High pressure building across the eastern slopes of Mexico will help tighten the pressure gradient across the Tehuantepec area early this week, supporting near-gale force winds over these waters tonight through the middle of the week. Winds will reach gale-force Mon night through Tue night. ...OFFSHORE WATERS WITHIN 250 NM OF CENTRAL AMERICA, COLOMBIA, AND WITHIN 750 NM OF ECUADOR... Fresh gap winds are over and downwind of the Gulf of Papagayo. Light to gentle winds are elsewhere north of the monsoon trough. Gentle to moderate S winds are noted between Colombia and the Galapagos Islands, with light to gentle winds elsewhere S of the monsoon trough. Seas of 4-5 ft prevail, except up to 6 ft in the Papagayo region. For the forecast, moderate to fresh winds will pulse at night across and well downstream of the Gulf of Papagayo region through the period, pulsing to strong speeds at night through the early morning hours tonight through mid-week. Light to gentle winds are expected S of the monsoon trough, increasing to moderate speeds between Colombia and the Galapagos Islands early this week. ...REMAINDER OF THE AREA... Please see above for more information on Post-Tropical Cyclone Ramon. Gentle to moderate winds persist outside of Ramon. NW swell continues to spread across the waters, with seas 8 ft or greater now roughly NW of a line from 00N130W to 26N114W. Seas with the swell are peaking at 11 to 12 ft from 11N to 30N between 122W and 140W. Combined seas are 5-7 ft elsewhere in mixed swell. For the forecast, the NW swell will continue to propagate southeastward, with seas greater than 8 ft covering much of the waters west of 120W into early this week. Winds and seas associated with Ramon are expected to cover a relatively small and localized area, with seas mixing with longer period NW swell. $$ Hagen
