000 AXPZ20 KNHC 172108 CCA TWDEP Tropical Weather Discussion...Corrected NWS National Hurricane Center Miami FL 1605 UTC Mon Aug 17 2020 Corrected Special Features section 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 1545 UTC. ...SPECIAL FEATURES...Corrected Recently upgraded Hurricane Genevieve is centered near 14.4N 102.8W or about 220 nm south-southwest of Zihuatanejo, Mexico and 650 nm southeast of the southern tip of Baja California at 17/1500 UTC moving WNW at 16 kt. The estimated minimum central pressure is 992 mb. Maximum s stained winds are 65 kt with gusts to 80 kt. Satellite imagery shows a thick banding feature coiling around the center of the cyclone. It consists of numerous moderate to strong type convection. Similar convection is embedded in a large band within 210 nm of the center in the western semicircle. This banding feature stretches northeastward to along and just inland the coast of Mexico between Puerto Angel and Manzanillo. Scattered moderate to isolated strong convection is within an outer banding, about 60 nm wide, from near 12N98W to 14N100W. The center of Genevieve is expected to move parallel to but well offshore the coast of southwestern Mexico during the next few days. Rapid strengthening is anticipated during the next couple of days, and Genevieve is forecast to become a major hurricane on Tue before a weakening trend begins on Wed. Large swell produced by Genevieve will begin affecting portions of the southern coast of Mexico today and will spread northward along the southwestern and west- central coast of Mexico to the Baja California peninsula through Wed. 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 extends along 112W from 04N to 20N, moving westward at 10-15 kt. This wave remains embedded in a very moist atmospheric environment. Scattered moderate to isolated strong convection is seen noted from 09N to 14N between 109W and 115W. A tropical wave has its axis along 127W from 03N to 20N, moving westward at about 10 kt. Only scattered showers and isolated thunderstorms are occurring within 60 nm either side of the wave axis from 10N to 13N. ...INTERTROPICAL CONVERGENCE ZONE/MONSOON TROUGH... The monsoon trough axis extends from the coast of northwestern Colombia near 10N76W, westward to across northern Costa Rica and northwestward from there to 13N93W and to 13N99W where it breaks down to the east of Hurricane Genevieve. It resumes at 13N109W and continues northwestward to 16N116W and to 16N121W and to 14N127W to the remnant low of former Tropical Depression Ten-E near 15N136W with pressure of 1007 mb and continues to 10N140W. Besides the convection described above, scattered to isolated strong convection is within 120 nm north of the trough between 93W-96W and within 120 nm NE quadrant of the low pressure near 15N136W. Scattered moderate convection is within 60 nm south of the trough between 91W-98W and also between 118W and 126W. OFFSHORE WATERS WITHIN 250 NM OF MEXICO... Please see the Special Features section above for details about recently upgraded Hurricane Genevieve, which is expected to rapidly strengthen while moving west-northwest parallel to but well offshore the coast of southwestern Mexico during the next few days. Genevieve will produce extremely dangerous, life- threatening marine conditions over the next several days as it crosses the offshore waters. Elsewhere, overnight scatterometer data shows light to gentle winds offshore of the Baja California peninsula. Seas range from 3-6 ft. Farther south, a broad area of fresh to strong cyclonic flow associated with Genevieve is noted off the coast of southern Mexico. A recent altimeter data pass depicted seas of 8 ft and greater extending up to 400 nm to the southeast of Hurricane Genevieve. OFFSHORE WATERS WITHIN 250 NM OF CENTRAL AMERICA, COLOMBIA, and WITHIN 750 NM OF ECUADOR... Winds and seas associated with Tropical Storm Genevieve have passed west of the Guatemala and El Salvador offshore waters, although some residual swell is still maintaining seas to 8 ft well offshore of Guatemala. Seas will continue subsiding through tonight as Genevieve moves away from the region. Elsewhere, gentle to moderate S to SW monsoon flow will freshen by midweek as the monsoon trough lifts northward. This will build seas to 7-9 ft off the coast of Costa Rica, Panama, and Ecuador. REMAINDER OF THE AREA... Please see the Special Features section above for information about recently upgraded Hurricane Genevieve. The remnant low of former Tropical Depression Fausto is centered near 23N125W with central pressure of 1008 mb. The low lacks deep convection as it moves over cooler water. Satellite imagery depicts the low as a swirl of broken to overcast low and mid- level clouds from about 23N to 27N and between 123W-129W. Only isolated showers are possible within these clouds. Additional weakening is expected as the remnant low spins down over the cooler waters during the next day or so. Global models indicate that it will dissipate by Wed morning. Overnight scatterometer data shows a broad area of fresh to locally strong southerly winds well SW of the center of Genevieve. This enhanced monsoon flow is likely producing seas of 8-10 ft roughly from 06N to 10N between 100W and 110W. The remnant low of Post-Tropical Cyclone Ten-E is centered near 15N136W, with fresh winds and 6-8 ft seas noted within 180 nm N semicircle. Otherwise, gentle to moderate winds prevail across the remaining waters with seas less than 8 ft. Generally moderate southerly monsoon flow will freshen during the middle and latter parts of the week, resulting in small areas of 8+ ft seas south of the monsoon trough. $$ Aguirre
