The following information is based on satellite imagery, weather observations, radar, and meteorological analysis. Based on 1200 UTC surface analysis and satellite imagery through 1530 UTC. A tropical wave is along 82W, extending north of 03N through Panama into the southwest Caribbean, moving west at 10 to 15 kt. Scattered moderate convection is noted 90 nm on either side of the wave axis along the coast of Nicaragua and Costa Rica. A tropical wave axis is along 94W north of 05N into southern Mexico, drifting west at 5 kt. Scattered showers are in the Vicinity of the wave axis. A tropical wave axis is along 112W, from 05N to 18N. It is moving west at 10 to 15 kt. Scattered moderate convection is from 09N to 15N between 111W and 117W. ...INTERTROPICAL CONVERGENCE ZONE/MONSOON TROUGH... The monsoon trough axis extends from 09N84W to 15103W, then west of the tropical wave from 14N105W to 11N123W to 11N140W. Scattered moderate convection is noted along the monsoon trough off the coasts of Nicaragua, Costa Rica, and El Salvador. Scattered moderate to isolated strong convection is noted from 09N to 13N between 118W and 130W and from 134W to 140W. OFFSHORE WATERS WITHIN 250 NM OF MEXICO... High pressure west of Baja California will support fresh NW winds north of Punta Eugenia through Wed night. Surface trough is noted from 12N105W to 17N103W with scattered moderate convection north of 15N to the coast of Mexico. Lower pressure north of the region will support moderate to fresh winds over the northern Gulf of California through Fri. A deep layer trough moving into the southwest US will allow pressure to lower north of the region tonight. This pattern will support moderate to fresh winds over the northern Gulf of California Tue and Wed. Similar conditions are possible in the northern Gulf at the end of the week. Farther south, light breezes and southerly swell will persist. Looking ahead, pulses of fresh to strong gap winds are possible in the Gulf of Tehuantepec region Fri night and Sat night. OFFSHORE WATERS WITHIN 250 NM OF CENTRAL AMERICA, COLOMBIA, and WITHIN 750 NM OF ECUADOR... The monsoon trough has lifted northward and has reached a position parallel to the coast of Central America and southern Mexico. This pattern will maintain scattered thunderstorms and gentle to moderate southerly winds through mid-week before the monsoon trough reforms farther south. Pulses of fresh offshore winds are likely in the Papagayo region Tue through Fri. REMAINDER OF THE AREA... A ridge of high pressure extends over the waters north of 20N. The pressure gradient between the ridge and the monsoon trough/ITCZ is supporting moderate NE trade winds north of the monsoon trough west of 120W with seas in the 5 to 7 ft range. Meanwhile, cross-equatorial southerly swell E of 125W will support seas of 5 to 7 feet through the week. $$ Torres
