Based on 0600 UTC surface analysis and satellite imagery through 0830 UTC. ...TROPICAL WAVES... A tropical wave has its axis along 87W, north of 07N to Honduras and into the NW Caribbean Sea, moving west at 10 to 15 kt. The majority of associated deep convection is found inland. A tropical wave has its axis along 102W, from 06N to 17N, moving west at around 10 kt. Associated convection is described below. A tropical wave has its axis along 139W, from 06N to 20N, moving west at around 15 kt. Associated convection is described below. ...INTERTROPICAL CONVERGENCE ZONE/MONSOON TROUGH... The monsoon trough extends off the coast of Central America near the Papagayo region near 11N86W to 14N103W to 13N120W to beyond 11N140W. Scattered moderate convection is noted from 04N to 14N between 80W and 96W, from 06N to 15N between 98W and 127W, and from 09N to 15N between 130W and 140W. OFFSHORE WATERS WITHIN 250 NM OF MEXICO... Winds are moderate or weaker across the offshore waters, including in the Gulf of California. Seas are 4-6 ft in the open waters, and 1-2 ft in the Gulf of California north of the entrance. Scattered moderate convection is noted in the southern Mexico offshore waters. For the forecast, winds may pulse to fresh at night offshore Baja California through Wed night, with moderate or weaker winds expected elsewhere. Pulsing fresh northerly winds may develop in the Gulf of Tehuantepec early Thu. A tropical wave located a few hundred miles south-southwest of Acapulco, Mexico is producing an area of disorganized showers and thunderstorms. Environmental conditions are forecast to be conducive for gradual development during the next several days, and a tropical depression could form later this week. The system is forecast to move west- northwestward or northwestward, likely remaining a few hundred miles off the coast of southwestern Mexico. This system has a low chance of developing in the next 48 hours and a medium chance of developing in 5 days. This system will lead to an increase of winds and seas starting Wed night through the end of the week in the southern Mexico offshore waters. OFFSHORE WATERS WITHIN 250 NM OF CENTRAL AMERICA, COLOMBIA, AND WITHIN 750 NM OF ECUADOR... Light to gentle winds prevail across the region, along with seas of 4 to 6 ft in S to SW swell. Some isolated to widely scattered showers and thunderstorms are noted offshore Panama northward in addition to moving off the Colombia coast. For the forecast, light to gentle variable winds will prevail north of the monsoon trough through the week, with gentle to moderate winds south of the monsoon trough. Winds may pulse to fresh off the Colombia and Ecuador coasts starting Wed and continuing into the weekend. Seas are also expected to slightly build during this time. REMAINDER OF THE AREA... High pressure centered well north of the area continues to dominate the weather pattern. Across the waters north of the monsoon trough and roughly west of 120W, gentle to moderate NE to E winds prevail. The latest ASCAT shows an area of fresh winds from 14N to 20N between 129W and 137W. Seas range 4-6 ft. Gentle to moderate S to SW winds and seas of 5-7 ft are south of the monsoon trough, except moderate to fresh between 98W and 117W where seas to 8 ft. Mainly light to gentle winds and 4-5 ft seas are elsewhere. Southerly swell with seas to 8 ft are reaching waters S of 01S and W of 108W. For the forecast, surface ridging will continue to dominate the forecast region north of the monsoon trough through midweek. The set of SW swell reaching near 03.4S and west of 100W is expected to subside by Tue night. A tropical wave located a few hundred miles south-southwest of Acapulco, Mexico is producing an area of disorganized showers and thunderstorms. Environmental conditions are forecast to be conducive for gradual development during the next several days, and a tropical depression could form later this week. The system is forecast to move west-northwestward or northwestward, likely remaining a few hundred miles off the coast of southwestern Mexico. This system has a low chance of formation over the next 48 hours and a medium chance in 5 days. $$ AReinhart
