000 AXPZ20 KNHC 311527 TWDEP Tropical Weather Discussion NWS National Hurricane Center Miami FL 1525 UTC Mon Aug 31 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 1200 UTC surface analysis and satellite imagery through 1500 UTC. ...TROPICAL WAVES... A tropical wave axis extends along 96W south of 17N, moving westward at 10-15 kt. Scattered moderate convection is noted from 07N to 13N between 94W and 102W. A tropical wave axis extends along 110W south of 18N, moving westward at 10-15 kt. Scattered moderate convection is noted from 09N to 12N between 105W and 110W. ...INTERTROPICAL CONVERGENCE ZONE/MONSOON TROUGH... The monsoon trough extends from 10N75W to 07N82W to 10N109W to 17N116W to 12N140W. Scattered moderate convection is occurring within 90 nm of the monsoon trough between 119W and 136W. OFFSHORE WATERS WITHIN 250 NM OF MEXICO... The remnant 1007 mb low of Iselle is analyzed near 25N113W this morning. There is no deep convection or significant winds/seas associated with the low. This feature will continue weakening and open up into a surface trough by Tue. Otherwise, a weak offshore pressure gradient prevails across the region. Gentle to moderate NW winds persist offshore of Baja California, with 4-6 ft seas based on recent altimeter data. Gentle to moderate southerly flow over the Gulf of California will pulse to locally fresh speeds tonight into Tue N of 29.5N. Elsewhere, light to gentle winds continue off the coast of southern Mexico. Looking ahead, the next gap wind event in the Gulf of Tehuantepec could begin Fri night. OFFSHORE WATERS WITHIN 250 NM OF CENTRAL AMERICA, COLOMBIA, and WITHIN 750 NM OF ECUADOR... The monsoon trough is analyzed across the offshore waters between 08N-09N this morning. Recent satellite and lightning data only show isolated, weak showers and thunderstorms near the trough. Gentle to moderate monsoonal flow will prevail across the waters roughly south of 10N this week. Southerly swell will result in 8 ft seas between the Galapagos Islands and Ecuador late tonight through at least Wed night. REMAINDER OF THE AREA... A weak high pressure ridge extends across the waters north of 15N and west of 125W this morning. The pressure gradient between this ridge and the monsoon trough is supporting gentle to moderate trades west of 130W, with 5-7 ft seas. Little change in these marine conditions is expected over the next several days. Elsewhere, moderate S to SW winds prevail south of the monsoon trough, with locally fresh winds possible between 95W and 110W. Northerly swell will support 8 ft seas across the far northern waters west of 127W tonight through Tue. A broad area of low pressure near 10N110W continues to produce disorganized showers and thunderstorms. Some gradual development of this system is possible during the next couple of days while it moves slowly westward or west-northwestward. This system has a low chance of tropical cyclone formation during the next 48 hours. Please see the latest eastern North Pacific Tropical Weather Outlook for more updates. $$ B Reinhart
