The following information is based on satellite imagery, weather observations, radar, and meteorological analysis. Based on 1200 UTC surface analysis and satellite imagery through 1500 UTC. ...TROPICAL WAVE... The axis of a tropical wave is near 88W from El Salvador southward to 05N, moving west around 15 to 20 kt. Nearby convection is described below. The axis of a tropical wave is near 104W, from 05N to 17N, moving west at around 15 kt. Nearby convection is described below. The axis of a tropical wave is near 116W, from 05N to 17N moving west around 15 kt. Nearby convection is described below. ...INTERTROPICAL CONVERGENCE ZONE/MONSOON TROUGH... The monsoon trough extends from 10N85W to 08N95W to 08N105W. Segments of the ITCZ extend from 08N105W to 09N115W, and from 09N118W to 12N130W to beyond 10N140W. Scattered moderate convection is evident from 08N to 12N between 88W and 91W, from 04N to 07N between 87W and 98W, and from 06N to 10N between 98W and 105W. ...OFFSHORE WATERS WITHIN 250 NM OF MEXICO... A plume of moderate northerly gap winds are in the immediate Gulf of Tehuantepec, with seas of 4-5 ft. Gentle to moderate winds are noted elsewhere across Mexican offshore waters, with 3-5 ft seas over the open waters, and 1-3 ft seas in the Gulf of California. Thunderstorm activity leftover from overnight is active off the coast of Chiapas, just south of Cabo Corrientes, and over the southern Gulf of California. For the forecast, expect moderate to fresh gap winds across the Gulf of Tehuantepec during the overnight hours through Mon, then fresh to strong thereafter. Gentle to moderate winds and moderate seas will persist elsewhere, except for locally gusty winds near clusters of showers and thunderstorms in portions of the Gulf of California during overnight hours. ...OFFSHORE WATERS WITHIN 250 NM OF CENTRAL AMERICA, COLOMBIA, AND WITHIN 750 NM OF ECUADOR... Showers and thunderstorms linger from overnight offshore of Colombia and Costa Rica. Moderate to fresh NE to E gap winds are likely over the Gulf of Papagayo. Moderate southerly winds are S of 03N, with seas of 4-6 ft in S-SW swell. Elsewhere, mainly light to gentle breezes and 3-4 ft seas are evident. For the forecast, fresh to strong gap winds will pulse across the Gulf of Papagayo each night through Thu night, with moderate to rough seas. Gentle to moderate winds and slight to moderate seas will persist elsewhere, except for locally gusty winds near clusters of showers and thunderstorms from Colombia to Costa Rica. ...REMAINDER OF THE AREA... A trough near 18N133W is all that remains of what was T.D. Four-E. Moderate winds and seas persist within 90 nm north of the trough, but conditions are improving. Gentle to moderate winds and moderate seas prevail elsewhere, except fresh SE winds S of the Equator and W of 115W. For the forecast, the remnant trough of Four-E will gradually dissipate as it moves westward. Elsewhere, moderate to occasionally fresh winds can be expected N of the convergence zone and W of 130W, with gentle to moderate winds elsewhere through the middle part of the week. Moderate seas will prevail, building to around 8 ft S of the Equator and W of 95W Mon night through Wed. $$ Christensen
