000 AXPZ20 KNHC 211544 TWDEP Tropical Weather Discussion NWS National Hurricane Center Miami FL 1434 UTC Fri Aug 21 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 1500 UTC. ...SPECIAL FEATURES... Tropical Storm Genevieve is centered near 25.3N 114.8W at 21/1500 UTC moving NW or 305 degrees at 9 kt. Estimated minimum central pressure is 1001 mb. Maximum sustained wind speed is 40 kt with gusts to 50 kt. Deep convection associated with the system has dissipated. Genevieve will continue to move away from the west coast of Baja California while weakening, and Genevieve is forecast to degenerate into a post-tropical cyclone later today. The remnant low should continue to spin down over cooler waters west of the Baja California peninsula during the next couple of days. Please read the latest NHC Public Advisory at: https://www.nhc.noaa.gov/text/MIATCPEP2.shtml and Forecast/ Advisory at https://www.nhc.noaa.gov/text/MIATCMEP2.shtml for more details. ...TROPICAL WAVES... A tropical wave axis is analyzed near 84W N of 01N. This is the tropical wave which helped spawn T.D. 14 in the western Caribbean. Scattered moderate convection is noted from 10N to 13N between 84W and 87W. Heavy rainfall could lead to flash flooding over portions of Central America through the weekend. A tropical wave axis is analyzed near 107W from 04N to 18N, moving W at 10-15 kt. Scattered moderate convection is noted from 10N to 13N between 105W and 107W. ...INTERTROPICAL CONVERGENCE ZONE/MONSOON TROUGH... The monsoon trough extends from 12N87W to 11N100W to 16N111W to 14N124W to 11N140W. Besides the convection described above, scattered moderate and isolated strong convection is noted from 13N to 17N between 110W and 118W. This convective activity is associated with a broad area of low pressure located several hundred miles southwest of the southwestern coast of Mexico. OFFSHORE WATERS WITHIN 250 NM OF MEXICO... Please see the Special Features section above for details about Tropical Storm Genevieve. Elsewhere, expect fresh to strong S to SE winds in the northern Gulf of California today with seas around 5-7 ft. OFFSHORE WATERS WITHIN 250 NM OF CENTRAL AMERICA, COLOMBIA, and WITHIN 750 NM OF ECUADOR... Moderate to fresh SW winds prevail south of the monsoon trough. Associated seas are 6-8 ft. Expect freshening winds and building seas off the coast of Central America through the upcoming weekend and into early next week. Seas will build to 8-10 ft offshore of Central America by this weekend in association with the strongest winds, then continue building to 9-11 ft early next week as monsoonal flow continues strengthening. REMAINDER OF THE AREA... A modest pressure gradient between high pressure north of the area and the monsoon trough is supporting gentle to moderate trades N of 20N and W of 125W. Moderate to locally fresh SW winds persist south of the monsoon trough. Seas are in the 7-9 ft range within these fresh trades. This monsoonal flow is expected to strengthen E of 115W this weekend into early next week, with seas building to 8-12 ft. $$ GR
