The following information is based on satellite imagery, weather observations, radar, and meteorological analysis. Based on 0600 UTC surface analysis and satellite imagery through 0915 UTC. ...SPECIAL FEATURES... Tropical Depression Iselle is centered near 22.3N 114.0W at 30/0900 UTC moving N at 6 kt. Estimated minimum central pressure is 1005 mb. Maximum sustained wind speed is 30 kt with gusts to 40 kt. Scattered moderate convection is noted from 20N to 23N between 112W and 116W. Additional weakening is expected, and Iselle is forecast to become post-tropical later today and will likely dissipate in a couple of days. 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 102W and N of 08N, moving westward at around 10-15 kt. Scattered moderate convection is from 06N to 22N between 100W and 110W. A tropical wave extends its axis along 86W and N of 05N, moving west at about 10 kt. Scattered moderate convection is N of 10N E of 93W. ...INTERTROPICAL CONVERGENCE ZONE/MONSOON TROUGH... The monsoon trough extends across Panama, then reaching to 07N81W to 16N94W to 21N109W...then resumes from 18N118W to 10N140W. Scattered moderate convection is within 90 nm N and 240 nm S of the boundary. OFFSHORE WATERS WITHIN 250 NM OF MEXICO... Refer to the section above for details on Tropical Depression 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 this morning. Expected seas are near 6 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 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. $$ ERA
