000 AXPZ20 KNHC 220300 TWDEP Tropical Weather Discussion NWS National Hurricane Center Miami FL 0405 UTC Wed Jul 22 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 0300 UTC. ...SPECIAL FEATURES... Tropical Storm Douglas is centered near 12.1N 126.7W at 0300 UTC, moving west at 13 kt. Estimated minimum central pressure is 998 mb. Maximum sustained winds are 55 kt with gusts to 65 kt. Numerous moderate to strong convection within 60 nm of the center. Scattered moderate isolated strong convection is elsewhere from 06N to 14N between 124W and 129W. Douglas is expected to intensify, and could become a hurricane overnight. 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 is along 86W, north of 02N into Central America, moving westward at 10 to 15 kt. Scattered moderate to strong convection is north of 09N between 85W and 88W. A tropical wave is along 96W, north of 02N into southern Mexico, moving westward at 10 kt. Scattered moderate isolated strong convection is from 08N to 12N between 94W and 98W. A tropical wave is along 110W, from 02N to 17N, moving westward at 10 to 15 kt. Isolated moderate convection is from 08N to 12N between 107W and 113W. ...INTERTROPICAL CONVERGENCE ZONE/MONSOON TROUGH... The monsoon trough axis extends from 09N79W in Panama to 09N100W to 12N120W. It resumes from 10N132W to 10N140W. In addition to convection mentioned above, scattered moderate isolated strong is from 07N to 13N between 90W and 105W. OFFSHORE WATERS WITHIN 250 NM OF MEXICO... The gradient between high pressure that ridges east-southeast from the northeast Pacific and a trough across Baja California is supporting fresh northwest winds west of Baja California Norte. Moderate to fresh southerly winds are expected east of the trough in the northern Gulf of California through Fri. Gentle to locally moderate winds will continue elsewhere through the weekend. OFFSHORE WATERS WITHIN 250 NM OF CENTRAL AMERICA, COLOMBIA, and WITHIN 750 NM OF ECUADOR... Widespread showers associated with an active monsoon trough and tropical waves passing across Central America into the eastern Pacific will continue into the weekend. Fresh south to southwest winds will persist south of the monsoon trough axis, along 08N to 09N, through Sun, with gradually building seas of 6 to 8 ft expected. REMAINDER OF THE AREA... Please see the Special Features section above for information on Tropical Storm Douglas. The remnant low of Post-Tropical Cyclone Seven-E centered near 19N136W lacks significant deep convection. The low is expected to continue weakening and move west of 140W during the next 24 hours, then dissipate by Wednesday night. High pressure located well north of the area extends a ridge into the northern waters. Outside of conditions associated with Tropical Storm Douglas, the pressure gradient between the high and the monsoon trough is supporting moderate trade winds north of the monsoon trough east of about 115W, along with seas in the 5 to 7 ft range. $$ Mundell
