The following information is based on satellite imagery, weather observations, radar, and meteorological analysis. Based on 0000 UTC surface analysis and satellite imagery through 0130 UTC. ...INTERTROPICAL CONVERGENCE ZONE/MONSOON TROUGH... A surface trough extends from near the Papagayo region at 10N86W to 05N94W. The ITCZ continues 05N94W to 10N111W, then resumes near 10N117W to 09N120W to 11N132W. No significant convection along the trough and ITCZ is noted. OFFSHORE WATERS WITHIN 250 NM OF MEXICO Moderate to fresh winds prevail over the northern Gulf of California. Fresh to strong N winds are developing in the Gulf of Tehuantepec this evening. Elsewhere, light to gentle winds prevail. Seas are 5 to 7 ft over the Gulf of Tehuantepec, and 4 to 6 ft elsewhere over the open waters off Mexico. Seas of 2 to 4 ft prevail over the northern Gulf of California, and 1 to 3 ft elsewhere across the Gulf. For the forecast, fresh to strong N winds will pulse in the Gulf of Tehuantepec through Sat, increasing to gale force Sat night through early next week. Moderate to fresh winds over the northern Gulf of California will diminish tonight. Fresh to strong winds are possible in the northern Gulf of California and offshore of Baja California Norte Tue night as a cold front moves through the region. Light to gentle winds will prevail elsewhere, reaching moderate speeds off Cabo Corrientes this weekend. OFFSHORE WATERS WITHIN 250 NM OF CENTRAL AMERICA, COLOMBIA, and WITHIN 750 NM OF ECUADOR Fresh to strong winds prevail in the Gulf of Papagayo. Moderate winds are noted in the Gulf of Panama. Light to gentle winds prevail elsewhere. Seas are in the 4 to 6 ft range across the offshore waters. For the forecast, winds will pulse to fresh to strong each night in the Gulf of Papagayo through early next week. Moderate to fresh winds will pulse in the Gulf of Panama each night through early next week. Light to gentle winds will prevail elsewhere. Fresh seas generated by a Gulf of Tehuantepec gap wind event will propagate into the waters offshore of Guatemala and El Salvador Sun night through early next week, peaking around 12 ft. REMAINDER OF THE AREA High pressure is centered well north of the area with a ridge extending SE into the waters north of 20N. A 1011 mb low pressure is centered near 13N135.5W with surface trough extending from 17N134W through the low to 09N136W. The pressure gradient between these features is supporting fresh to strong winds from 13N to 20N between 130W and 138W. Seas are 8 to 10 ft over this area. A 1008 mb low pressure is centered near 13N114.5W with moderate winds and 5 to 6 ft in the vicinity. Gentle to moderate winds are in the vicinity of the ITCZ. Light to gentle winds are elsewhere north of the ITCZ, with seas of 5 to 7 ft. Gentle to moderate winds prevail south of the ITCZ, with seas in the 5 to 7 ft range. For the forecast, the low pressure areas and trough will gradually dissipate through the end of the week allowing for associated winds and seas to diminish and subside. Fairly tranquil marine conditions will then prevail across the open waters through Sun. The pressure gradient will tighten north of the ITCZ Sun night, with trades increasing to moderate to fresh. A cold front may drop south of 30N Tue night, bringing increasing winds and seas over the north central waters toward mid-week. $$ Lewitsky
