000 AXPZ20 KNHC 250820 TWDEP Tropical Weather Discussion NWS National Hurricane Center Miami FL 820 UTC Sat Jul 25 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 0600 UTC surface analysis and satellite imagery through 0900 UTC. ...TROPICAL WAVES... A tropical wave axis is near 89W, from 02N into Guatemala, moving west at 10 to 15 kt. Numerous moderate to scattered strong convection is noted from 06N to 08N between 89W and 92W. A tropical wave is along 107W from 02N to 18N moving westward at 15 kt. Scattered moderate to isolated strong convection is noted from 07N to 10N between 105W and 108W. A weak tropical wave extends from 02N to 18N with axis near 119W, moving westward at 15 to 20 kt. No significant convection is noted near this wave. A tropical wave extends from 02N to 18N with axis near 130W, moving westward at 15 to 20 kt. Scattered moderate convection is from 07N to 09N between 127W and 132W. ...INTERTROPICAL CONVERGENCE ZONE/MONSOON TROUGH... The monsoon trough axis extends from 10N84W to 11N120W to 07N135W. The intertropical convergence zone continues from 07N135W to beyond 140W. Aside from what is noted in tropical waves section above, scattered moderate to isolated strong convection is observed from 06N to 10N between 83W and 97W. Scattered moderate convection is also noted from 10N to 13N between 120W and 125W. OFFSHORE WATERS WITHIN 250 NM OF MEXICO... High pressure west of Baja California will support moderate to locally fresh NW winds north of Cabo San Lazaro through mid week. through A deep layer trough moving into the southwest US will allow pressure to lower pressure north of the region by Tue. This pattern will support moderate to fresh winds over the northern Gulf of California through mid week. Farther south, light breezes and southerly swell will persist through the period. Looking ahead, the monsoon trough will lift northward to off the coast of southern Mexico by Tue. This will support increased showers and thunderstorms, mainly at night. Weak low pressure may form along the trough off Guerrero and Michoacan into mid week, then move westward. OFFSHORE WATERS WITHIN 250 NM OF CENTRAL AMERICA, COLOMBIA, and WITHIN 750 NM OF ECUADOR.. The monsoon trough is currently along roughly 10N, but will lift northward early in the week to a position parallel to the coast of Central America. This pattern will maintain scattered thunderstorms and gentle to moderate southerly winds. Meanwhile long period SW swell will gradually subside off Central America by Mon. 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 will continue to move into region, occasionally supporting combined seas nearing 8 ft east of 120W into Sun. $$ Christensen
