000 AXPZ20 KNHC 080847 TWDEP Tropical Weather Discussion NWS National Hurricane Center Miami FL 0840 UTC Thu Aug 8 2019 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 0840 UTC. ...TROPICAL WAVES... The axis of a tropical wave is near 81W N of 04N, moving W around 15 kt. There is no significant convection associated with this wave over the Pacific. The axis of a tropical wave is near 91W N of 04N, moving W around 10 kt. Scattered moderate and isolated strong convection is noted N of 07N between 87W and 95W. The axis of a tropical wave is near 100W N of 04N, moving W around 15 kt. Scattered moderate and isolated strong convection is noted from 13N to 16N between 97W and 102W. This tropical wave will continue to be closely monitored for the potential for tropical cyclone formation. The latest Tropical Weather Outlook gives the system a 50 percent chance for tropical cyclogenesis within the next 5 days. Please refer to the latest eastern north Pacific Tropical Weather Outlook for more information. The axis of a tropical wave is near 117W from 04N to 18N, moving W around 15 kt. Scattered moderate convection is noted from 08N to 10N between 115W and 120W. The axis of a tropical wave is near 137W from 04N to 18N, moving W around 15 kt. Scattered moderate convection is noted from 10N to 14N between 135W and 140W. ...INTERTROPICAL CONVERGENCE ZONE/MONSOON TROUGH... The monsoon trough extends from 08N78W to 09N84W to 12N100W to 09N125W to 11N131W. Scattered moderate isolated strong convection is noted from 07N to 11N between 103W and 115W. Scattered moderate convection is noted from 08N to 10N between 120W and 130W. OFFSHORE WATERS WITHIN 250 NM OF MEXICO... A high pressure ridge will dominate the waters west of Baja California this week with little change in wind and sea conditions. A surface trough over the Baja Peninsula will generally maintain gentle to moderate SE to S winds over the Gulf of California through the forecast period. Long period SE and SW swell will propagate into the forecast waters tonight. However, combined seas will remain less than 8 ft. OFFSHORE WATERS WITHIN 250 NM OF CENTRAL AMERICA, COLOMBIA, AND WITHIN 750 NM OF ECUADOR... Moderate winds over the Gulf of Papagayo could become fresh Sun. Gentle to moderate S to SW winds will prevail south of the monsoon trough through the forecast period. Long period SW swell will move into the southern waters today. This will cause seas to build to between 6 and 9 ft between the coast of Ecuador and the Galapagos Islands tonight through Sun night. REMAINDER OF THE AREA... High pressure prevails over the forecast waters N of 20N. Moderate to fresh winds prevail from 13N to 20N W of 135W where the pressure gradient is enhanced between high pressure centered N of the area near 31N139W and a tropical wave near 137W. Gentle to moderate winds prevail across much of the remaining waters N of the monsoon trough. S of the monsoon trough, moderate to fresh southerly wind continues due to the pressure gradient between the trough and high pressure over the southeast Pacific. The moderate to fresh winds are helping enhance surface convergence, producing active weather S of the monsoon trough. Long period SW and SE swell generated from the southern hemisphere will continue to propagate across the forecast waters. Seas will generally be below 8 feet until late tonight when higher seas will push across the equator. The area of seas greater than 8 feet will expand northward to around 10N between 95W and 125W Sat night through Mon. $$ AL
