000 AXPZ20 KNHC 300304 TWDEP Tropical Weather Discussion NWS National Hurricane Center Miami FL 0300 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 0000 UTC surface analysis and satellite imagery through 0230 UTC. ...SPECIAL FEATURES... Tropical Storm Iselle is centered near 21.8N 114.2W at 30/0300 UTC moving NNE at 8 kt. Estimated minimum central pressure is 1004 mb. Maximum sustained wind speed is 35 kt with gusts to 45 kt. Scattered moderate convection is noted from 17N to 23N between 112W and 119W. A turn toward the north is expected during the next several hours with this motion expected to continue through Sunday. This should be followed by a turn to the northwest. Satellite imagery indicates that Iselle is becoming less organized, and it is expected to weaken to a depression on Sunday. The depression should then degenerate into a remnant low by late Sunday. 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. ...TROPICAL WAVES... A tropical wave extends its axis along 101W and N of 08N, moving westward at around 10-15 kt. Scattered moderate convection is from 10N to 20N between 99W and 105W. A tropical wave extends its axis along 86W and N of 04N, moving west at about 10 kt. Scattered moderate convection is N of 10N E of 87W. ...INTERTROPICAL CONVERGENCE ZONE/MONSOON TROUGH... The monsoon trough extends across Panama and Costa Rica, then reaching to 10N36W to 16N95W to 18N110W. Scattered moderate convection is within 90 nm N and 210 nm S of the boundary. OFFSHORE WATERS WITHIN 250 NM OF MEXICO... Refer to the section above for details on Tropical Storm Iselle. An elongated area of low pressure over the SW CONUS extending to the northern Gulf of California will slightly deepen and continue to support fresh to strong SE winds in that region through tonight. Expected seas are near 7 ft. Elsewhere, light to gentle variable winds will dominate the remainder offshore waters through the middle of the week. 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 the middle of the week. REMAINDER OF THE AREA... Moderate to locally fresh NE winds will dominate across the forecast waters N of 10N W of 130W 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. $$ ERA
