The following information is based on satellite imagery, weather observations, radar, and meteorological analysis. Based on 0000 UTC surface analysis and satellite imagery through 0300 UTC. ...TROPICAL WAVES... A tropical wave has its axis along 93W, just northwest of the Galapagos Islands, north of 03N to southern Mexico, moving west at around 10 kt. Nearby convection is displaced to the west of the tropical wave axis and is described below. A tropical wave has its axis along 117W from 03N to 16N southwest of Clarion Island, moving west at around 10 kt. Associated convection is described below. A tropical wave is along 123W, from 03N to 21N, moving west at around 10 kt. Associated convection is described below. ...INTERTROPICAL CONVERGENCE ZONE/MONSOON TROUGH... The monsoon trough extends from the coast of Nicaragua near 12N87W to 13N103W to 15N112W to beyond 11N140W. Scattered moderate convection is noted from 07N to 17N between 94W and 131W and from 11N to 16N between 134W and 140W. OFFSHORE WATERS WITHIN 250 NM OF MEXICO... Weak surface ridging extending across the offshore waters from the northwest is supporting mainly light to gentle winds this evening. Moderate northerly winds are noted across the Baja California Sur coastline. Seas are 4 to 6 ft in mainly long- period SW swell, mixed with NW swell offshore Baja California. In the Gulf of California, seas are 3 ft or less north of the entrance. For the forecast, the pressure gradient will tighten slightly offshore Baja California by Fri night, which will lead to winds increasing to moderate to fresh just offshore through early next week. Mainly gentle variable winds will prevail elsewhere, except for the Gulf of California where moderate to locally fresh SE winds will occur Sat into Sun. OFFSHORE WATERS WITHIN 250 NM OF CENTRAL AMERICA, COLOMBIA, AND WITHIN 750 NM OF ECUADOR... Light to gentle variable winds are north of the monsoon trough, with seas of 4 to 6 ft in SW swell. South of the monsoon trough, gentle to locally moderate southerly winds prevails, with seas of 5 to 7 ft in S to SW swell, except 3 to 6 ft offshore Colombia. Showers and isolated thunderstorms are noted in the Gulf of Panama and offshore Colombia. For the forecast, mainly gentle onshore winds will prevail north of the monsoon trough with gentle to moderate southerly winds south of the monsoon trough. Winds are expected to pulse locally to fresh offshore southern Colombia and Ecuador early Sat through Sat evening. Southerly swell with moderate seas will propagate across the Ecuador, The Galapagos, and Colombia offshore waters through the weekend. REMAINDER OF THE AREA... High pressure centered well north of the area continues to dominate the weather pattern for waters north of the monsoon trough and west of 120W. Mainly moderate NE winds prevail across this area with seas of 5 to 7 ft. Gentle winds and 5 to 6 ft seas are elsewhere north of the monsoon trough. Gentle to moderate southerly winds and seas of 5 to 8 ft are south of the monsoon trough in SW swell, highest near and just north of the Equator. For the forecast, surface ridging will continue to dominate the forecast region north of the monsoon trough through the weekend and into early next week. Seas around 8 ft from the Equator to 10N will subside late tonight. A new set of SW swell may breach 03.4S and west of 100W Mon night. Otherwise, mainly 4 to 7 ft seas will prevail into early next week. $$ AReinhart
