The following information is based on satellite imagery, weather observations, radar, and meteorological analysis. Based on 1200 UTC surface analysis and satellite imagery through 1500 UTC. ...SPECIAL FEATURES...

The depression may become a tropical storm later today. 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 has an axis along 112W from 05N to 17N, just south of the Revillagigedo Islands, moving west at 5 to 10 kt. Scattered moderate convection is noted from 07N to 12N between 107W and 117W. A tropical wave has its axis along 135W from 05N to 17N, moving west at 5 to 10 kt. Scattered moderate convection is noted from 06N to 13N between 130W and 140W. ...INTERTROPICAL CONVERGENCE ZONE/MONSOON TROUGH... The monsoon trough extends from the coast of Costa Rica near 09N84W to 08N89W to near newly-formed Tropical Depression Nine-E at 14N106W to 10N114W to 07N140W. Other than the convection described above,scattered moderate and isolated strong convection is noted within 120 nm either side of the monsoon trough between 117W and 130W. Scattered moderate convection is noted from 04N to 10N between 79W and 87W. OFFSHORE WATERS WITHIN 250 NM OF MEXICO... Refer to the Special Features section above for details on newly formed Tropical Depression Nine-E. Numerous moderate to isolated strong convection that moved offshore Mexico overnight continues to impact areas between the southern Gulf of California and Cabo Corrientes. Moderate to locally fresh NW-N winds prevail across the Baja California offshore waters, where seas are 4 to 6 ft. Fresh winds are pulsing in the Gulf of Tehuantepec. Mainly light to gentle winds are noted elsewhere away from Tropical Depression Nine-E, including in the Gulf of California. Seas are 3 to 5 ft across this area, except 3 ft or less north of the entrance to the Gulf of California, and 5 to 7 ft offshore Oaxaca and Chiapas. For the forecast, aside from the impacts from Tropical Depression Nine-E, described in the Special Features section above, fresh winds will pulse over the Tehuantepec area from through Tue, occasionally strong during the late night and early morning hours. Moderate to locally fresh winds will pulse from near Punta Eugenia northward through tonight. OFFSHORE WATERS WITHIN 250 NM OF CENTRAL AMERICA, COLOMBIA, AND WITHIN 750 NM OF ECUADOR... Fresh winds are in the Papagayo region. Elsewhere, gentle winds prevail north of the monsoon trough with moderate S to SW winds to the south of the monsoon trough, except locally fresh from the Equator to 04N between 79W and 88W. Seas are mainly 4 to 6 ft, locally to 7 ft in the area of fresh winds. Scattered showers and isolated thunderstorms are offshore Colombia northward. For the forecast, gentle to moderate winds will prevail, pulsing to fresh in the Papagayo region into early next week, as well as offshore Ecuador to 500 nm through the weekend. REMAINDER OF THE AREA... Refer to the Special Features section above for details newly formed Tropical Depression Nine-E. A surface trough is noted from 20N139W to 18N137W. Locally fresh winds and seas to near 7 ft area occurring just NW of this feature. Another trough is located from 30N132W to 27N133W. Otherwise, a broad and weak ridge dominates the waters north of 24N, with light to gentle variable winds and 4 to 5 ft seas. Moderate to locally fresh trades are north of the monsoon trough to 24N and west of 120W where the pressure gradient between the ridging and troughing is tightest. Moderate to locally fresh winds prevail south of the monsoon trough and ITCZ, except gentle winds between 95W and 100W. Seas are mainly 4 to 7 ft across the remainder of the open waters. For the forecast, light to gentle winds will prevail north of 24N and west of 125W for the start of the weekend. Moderate to locally fresh winds will prevail elsewhere north of the monsoon trough and west of 120W, with gentle to moderate winds elsewhere. Seas of 4 to 7 ft will dominate the open waters, building to 7 to 9 ft over the west-central waters by the end of the weekend into next week with a fresh and elongated fetch of trades. Seas may also build to around 8 ft near 03.4S early next week in a southerly swell. An area of low pressure could form over the far western portion of the eastern Pacific basin or the far eastern portion of the central Pacific basin late this weekend. Environmental conditions could allow for some gradual development of this system, and a tropical depression could form when it moves quickly westward over the central Pacific basin during the early to middle part of next week. Further information on this system can be found in Tropical Weather Outlooks issued by the Central Pacific Hurricane Center at hurricanes.gov/?cpac. Development is not expected over the next 48 hours, but there is a medium chance of development within the next 5 days. $$ KONARIK
