The following information is based on satellite imagery, weather observations, radar, and meteorological analysis. Based on 0600 UTC surface analysis and satellite imagery through 0800 UTC. ...TROPICAL WAVES... A tropical wave is along 81W, extending north of 04N through Panama into the southwest Caribbean, moving west at 10 to 15 kt. Scattered moderate convection is noted east of the tropical wave axis from 05N to 07N east of 80W. A tropical wave axis is along 92W north of 03N into southern Mexico, drifting west at 5 kt. No significant convection is observed near the wave axis. A tropical wave axis is along 112W/113W, from 05N to 17N. It is moving west at 10 to 15 kt. Scattered moderate convection is from 10N to 15N between 110W and 115W. ...INTERTROPICAL CONVERGENCE ZONE/MONSOON TROUGH... The monsoon trough axis extends from 09N85W to 14N91W to 09N140W. Scattered moderate convection is noted along the monsoon trough off the coasts of Nicaragua and El Salvador. Scattered moderate to isolated strong convection is noted from 15N to 17N between 101W and 104W. Scattered moderate convection is from 10N to 15N between 110W and 115W. Scattered moderate to isolated strong convection is observed from 12N to 14N between 123W and 125W. 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. 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. $$ Christensen
