000 AXPZ20 KNHC 251921 TWDEP Tropical Weather Discussion NWS National Hurricane Center Miami FL 1921 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 1800 UTC surface analysis and satellite imagery through 1900 UTC. ...TROPICAL WAVES... A tropical wave that is partially still in the eastern Caribbean extends along 80W from Panama to Ecuador, moving W at 10 to 15 kt. Scattered moderate to isolated strong convection is from 03N to 09N E of 85W. A tropical wave axis is near 93W, from 02N into southern Mexico, moving west at 10 to 15 kt. Numerous moderate to strong convection is noted from 06N to 09N between 87W and 101W. A tropical wave is along 111W from 02N to 18N moving westward at 10 to 15 kt. Scattered moderate to isolated strong convection is noted from 06N to 10N between 105W and 112W. A weak tropical wave extends from 02N to 18N with axis near 121W, moving westward at 10 to 15 kt. Scattered moderate convection has developed from 05N to 09N between 115W and 121W. A tropical wave extends from 02N to 18N with axis near 132W, moving westward at 10 to 15 kt. Scattered moderate convection is from 06N to 11N between 129W and 138W. ...INTERTROPICAL CONVERGENCE ZONE/MONSOON TROUGH... The monsoon trough axis extends from 10N84W to 11N113W to 07N135W. The intertropical convergence zone continues from 07N135W to beyond 08N140W. Aside from what is noted in tropical waves section above, scattered moderate to isolated strong convection is observed from 06N to 11N between 101W and 105W. 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 into late next week. A deep layer trough moving into the southwest US will allow pressure to lower north of the region by Tue. This pattern will support moderate to fresh winds over the northern Gulf of California late Tue into Wed. 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. Pulses of moderate to locally fresh gap winds are possible in the Gulf of Tehuantepec region Wed through Fri nights. 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 Sun night. Pulses of moderate to locally fresh offshore winds may occur in the Papagayo region Wed and Thu nights. 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 115W through tonight. $$ KONARIK
