000 AXPZ20 KNHC 302202 TWDEP Tropical Weather Discussion NWS National Hurricane Center Miami FL 2141 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 1800 UTC surface analysis and satellite imagery through 2130 UTC. ...TROPICAL WAVES... A tropical wave extends N of 05N with axis near 91W, moving westward at around 10-15 kt. Scattered moderate convection and isolated tstms are from 06N to 14N between 87W and 97W. A tropical wave extends N of 06N with axis near 105W, moving west at about 10-15 kt. Scattered moderate isolated strong convection is from 07N to 13N between 103W and 114W, 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... Post-Tropical Cyclone Iselle is centered near 23.7N 113.3W at 30/2100 UTC moving N at 7 kt. Estimated minimum central pressure is 1007 mb. Maximum sustained wind speed is 25 kt with gusts to 35 kt. There is no deep convection associated with the cyclone. Iselle should gradually lose strength during the next day or so before decaying into a surface trough on Tuesday. 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. South of the monsoon trough, moderate south- southwest flow will be dominant through Fri. REMAINDER OF THE AREA... Moderate to locally fresh NE winds will dominate across the forecast waters N of the monsoon trough W of 120W around a nearly stationary surface ridge that will prevail through the middle of the week. Winds around the ridge will gradually diminish Mon through Tue as Iselle dissipates and the pressure gradient across the area weakens. Elsewhere, northerly swell will support seas to 8 ft across the northern waters Mon through Wed. Otherwise, a tropical wave will move SW of the Baja California offshore waters by Wed and will support moderate NE winds between the monsoon and 20N through Fri. $$ Ramos
