000 AXPZ20 KNHC 151452 TWDEP Tropical Weather Discussion NWS National Hurricane Center Miami FL 1349 UTC Sat Aug 15 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 1450 UTC. ...SPECIAL FEATURES... Tropical Depression Ten-E is centered near 13.2N 133.7W at 15/1500 UTC moving W at 2 kt. Estimated minimum central pressure is 1004 mb. Maximum sustained wind speed is 30 kt with gusts to 40 kt. Scattered moderate convection is noted from 12N to 14N between 133W and 136W. Maximum seas are 11 to 12 ft. Please read the latest NHC Public Advisory at https://www.nhc.noaa.gov/text/MIATCPEP5.shtml and Forecast/ Advisory at https://www.nhc.noaa.gov/text/MIATCMEP5.shtml for more details. A tropical wave axis is near 90W, north of 01N into Central America. A 1008 mb area of low pressure is along this wave near 10N90W. Scattered moderate to strong convection is noted from 07N to 13N between 86W and 95W. Conditions are conducive for development of the low, and a tropical depression or storm is likely to form this weekend or early next week while the system moves west- northwestward south of the southwestern coast of Mexico. An area of low pressure near 15.5N118W is associated with a tropical wave. Scattered moderate to strong convection is noted from 14N to 19N between 115W and 121W. Environmental conditions appear favorable for further development today and tomorrow. A tropical depression is likely to form while the system moves slowly north-northwestward or northward during the next couple of days. An area of low pressure centered SW of the southern tip of Baja California near 22N114W has moved over colder waters and further development is unlikely. Scattered moderate convection is noted from 20N to 23N between 110W and 115W. ...TROPICAL WAVES... A tropical wave axis is near 104W north of 01N, moving W at 10 to 15 kt. Scattered moderate isolated strong convection was noted from 06N to 12N between 100W and 110W. Please see special features section above for more on the tropical waves near 90W and 118W, and tropical cyclone potential. ...INTERTROPICAL CONVERGENCE ZONE/MONSOON TROUGH... The monsoon trough extends from 10N85W to 10N100W to 21N113W to 12N130W. Aside from convection noted with the tropical waves and special features, scattered moderate convection is noted within 90 nm N and 150 nm S of the monsoon trough between 122W and 130W. OFFSHORE WATERS WITHIN 250 NM OF MEXICO... Moderate SE flow across the Gulf of California. The area of low pressure SW of the southern tip of Baja California is moving westward, and weakening. Fresh to occasionally strong gap winds will pulse across the Gulf of Tehuantepec this weekend. A low pressure near 10N90W is expected to develop into a tropical cyclone this weekend or early next week as it moves W-NW offshore of the southwestern coast of Mexico. Expect strong winds and building seas over the southern Mexico offshore waters associated to this feature. OFFSHORE WATERS WITHIN 250 NM OF CENTRAL AMERICA, COLOMBIA, and WITHIN 750 NM OF ECUADOR... Please see the Special Features section for information about the potential for tropical cyclone formation associated with low pressure that is west of Central America near 10N90W. This system will bring strong winds and large seas to the offshore waters of Guatemala, El Salvador, and Nicaragua this weekend. Winds and seas will subside early next week as the system moves W-NW offshore of southern Mexico. Fresh to strong S to SW winds prevail offshore of Costa Rica and Panama. Seas are generally 6-8 ft in this enhanced monsoonal flow. Fresh winds will pulse overnight across the Gulf of Papagayo region. REMAINDER OF THE AREA... Please see the Special Features section for information about Tropical Depression Ten-E, as well as the potential for tropical cyclone development elsewhere across the eastern North Pacific basin. Gentle to moderate NE winds prevail across the waters N of 15N and W of 120W. Besides the areas described in the Special Features section above, generally moderate to fresh SW monsoon flow prevails south of the monsoon trough. $$ AL/Mundell
