000 AXPZ20 KNHC 301605 TWDEP Tropical Weather Discussion NWS National Hurricane Center Miami FL 1536 UTC Sun Aug 30 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 1545 UTC. ...TROPICAL WAVES... A tropical wave extends N of 05N with axis near 89W, moving westward at around 10-15 kt. Isolated showers and tstms are from 07N to 13N between 86W and 95W. A tropical wave extends N of 06N with axis near 104W, moving west at about 10-15 kt. Scattered moderate isolated strong convection is from 05N to 14N between 100W and 113W, and N of 15N between 100W and 108W. ...INTERTROPICAL CONVERGENCE ZONE/MONSOON TROUGH... The monsoon trough extends from 10N85W to 11N100W to 11N110W, then resumes near 18N118W and continues along 13N130W to 10N140W. Scattered moderate convection is within 120 nm N and 210 nm S of the boundary. OFFSHORE WATERS WITHIN 250 NM OF MEXICO... Tropical Depression Iselle is centered near 23.0N 113.3W at 30/1500 UTC moving N at 7 kt. Estimated minimum central pressure is 1006 mb. Maximum sustained wind speed is 30 kt with gusts to 40 kt. There is no deep convection associated with the cyclone. Iselle is forecast to degenerate into a remnant low later today and decay into a trough of low pressure by Tuesday. Please read the latest NHC Public Advisory at https://www.nhc.noaa.gov/text/MIATCPEP4.shtml and Forecast/ Advisory at https://www.nhc.noaa.gov/text/MIATCMEP4.shtml for more details. An elongated area of low pressure over the SW CONUS extending to the northern Gulf of California will continue to support moderate to locally fresh SE winds in that region through this evening. Expected seas are near 6 ft. Elsewhere, light to gentle variable winds will dominate the remainder offshore waters through Thu. Looking ahead, the next gap wind event in the Gulf of Tehuantepec is forecast to begin Fri, continuing to Sat with fresh to locally strong winds at night. OFFSHORE WATERS WITHIN 250 NM OF CENTRAL AMERICA, COLOMBIA, and WITHIN 750 NM OF ECUADOR... Light to gentle variable winds will dominate the waters N of the monsoon trough, except for moderate wind pulses off the Gulf of Papagayo at night. South of the monsoon trough, moderate south- southwest flow will be dominant through Thu. REMAINDER OF THE AREA... Moderate to locally fresh NE winds will dominate across the forecast waters N of 12N W of 125W around a nearly stationary surface ridge through Mon. Winds then will gradually diminish through the middle of the week as Iselle dissipates and the pressure gradient across the area weakens. Elsewhere, northerly swell will support seas to 9 ft across the northern waters Mon evening through Wed. $$ Ramos
