000 AXPZ20 KNHC 282117 TWDEP Tropical Weather Discussion NWS National Hurricane Center Miami FL 2100 UTC Tue Jul 28 2020 Tropical Weather Discussion for the eastern Pacific Ocean from the Equator to 32N, east of 140W. The following information is based on satellite imagery, weather observations, radar, and meteorological analysis. Based on 1800 UTC surface analysis and satellite imagery through 2030 UTC. ...TROPICAL WAVES... A tropical wave is along 83W, extending north of 04N through Costa Rica into the southwest Caribbean, moving west at 10 to 15 kt. Scattered moderate isolated strong convection is noted over the SW Caribbean near the coast of Nicaragua and Costa Rica. Scattered showers are seen south of 08N. A tropical wave axis is along 94W north of 04N into southern Mexico, drifting west at 5 kt. Scattered showers are in the vicinity of the wave axis. A tropical wave axis is along 113W, from 05N to 17N. It is moving west at 10 to 15 kt. Scattered moderate convection is from 10N to 15N between 112W and 118W near the monsoon trough. ...INTERTROPICAL CONVERGENCE ZONE/MONSOON TROUGH... The monsoon trough axis extends from 09N84W to 15N103W, then west of the surface trough near 14N106W to 11N122W to 10N140W. 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 14N to 17N between 100W and 105W and from 119W to 140W. OFFSHORE WATERS WITHIN 250 NM OF MEXICO... Surface trough is noted from 14N105W to 18N103W. Scattered moderate isolated strong convection extends 180 nm east of the trough and 80 nm to the west. 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 through Sun 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 16N. The pressure gradient between the ridge and the monsoon trough/ITCZ is supporting moderate NE trade winds north of the monsoon trough west of 116W which is well depicted by the latest ASCAT data. Seas in this region range between 5 to 7 ft. Meanwhile, cross-equatorial southerly swell E of 125W will support seas of 5 to 7 feet through the week. $$ MTorres
