000 AXPZ20 KNHC 020352 TWDEP Tropical Weather Discussion NWS National Hurricane Center Miami FL 0405 UTC Tue Aug 2 2022 Tropical Weather Discussion for the eastern Pacific Ocean from 03.4S to 30N, east of 120W including the Gulf of California, and from the Equator to 30N, between 120W and 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 0330 UTC. ...SPECIAL FEATURES... Tropical Storm Frank is centered near 23.4N 124.0W at 02/0300 UTC and moving NW at 8 kt. Estimated minimum central pressure is 999 mb. Maximum sustained wind speed is 40 kt with gusts to 50 kt. Peak seas are currently 20 ft. Scattered moderate convection is noted from 22N to 24N between 122W and 124W. Frank is expected to make a gradual turn toward the north-northwest, north, and then north- northeast at a slightly faster forward speed through Thursday. Additional weakening is forecast, and Frank is expected to become post-tropical by late Tuesday. Seas will drop below 12 ft by Tue night. 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 Depression Georgette is centered near 13.5N 131.2W at 02/0300 UTC and moving WNW at 4 kt. Estimated minimum central pressure is 1006 mb. Maximum sustained wind speed is 30 kt with gusts to 40 kt. Peak seas are currently 9 ft. Scattered moderate convection is noted from 12N to 15N between 128W and 132W. The depression has been meandering during the past few hours but a slow north-northeastward motion is expected to start overnight, and this motion should continue through Wednesday. A turn to the west along with an increase in forward speed is forecast to occur on Thursday. Little change in strength is forecast during the next few days, and Georgette could degenerate into a remnant low at any time. This system will also maintain at least 8 ft seas through Thu morning.

A tropical wave has its axis along 88W from 02N to the Nicaragua coast, moving westward around 10 kt. Scattered moderate convection is noted from 03N to 08N between 86W and 93W. A tropical wave has its axis along 112W from 02N to 18N, moving westward around 10 kt. Scattered moderate convection is from 06N to 15N between 110W and 126W. ...INTERTROPICAL CONVERGENCE ZONE/MONSOON TROUGH... The monsoon trough extends from the coast of Costa Rica near 08N82W to 09N99W to 14N114W. The ITCZ extends from 11N133W to beyond 09N140W. Scattered moderate isolated strong convection is noted from 06N to 14N between 78W and 116W. Scattered moderate convection is noted from 06N to 16N between 120W and 140W. OFFSHORE WATERS WITHIN 250 NM OF MEXICO... Please see the Special Features section above for details on Tropical Storm Frank. A weak ridge is located between the Baja California peninsula and tropical cyclone Frank. Light to gentle winds are near Baja California with the exception of gentle to moderate E to SE winds over the outer offshore waters. Gentle to moderate winds are noted near Los Cabos to the entrance of the Gulf of California, and also over the northern Gulf of California. Mainly gentle southeast to south winds are over the rest of the Gulf. Light to gentle winds are over the remainder of the Mexican offshore waters except in the Gulf of Tehuantepec where fresh to strong northerly winds are blowing with seas of 6-7 ft. Seas generated by Frank continue to propagate across the waters W of Baja California with seas of 6 to 9 ft W of 110W. For the forecast, Tropical Storm Frank will continue to pull away from the offshore forecast waters over the next few days as it further weakens while moving northwestward beyond 30N late on Wed. Frank will move to 23.6N 123.7W this evening, 25.1N 125.1W Tue morning, weaken to a remnant low near 26.9N 126.2W Tue evening, 28.8N 126.9W Wed morning, 30.8N 127.2W Wed evening, and 32.8N 127.0W Thu morning. Frank will dissipate early Fri. For the forecast outside of Frank, gentle to moderate E to SE winds and seas in the 6 to 9 ft range associated with the outer periphery of Frank will continue to affect the outer offshore waters of Baja California through late Tue. Then, moderate to fresh NW to N winds will return to the area, mainly N of Punta Eugenia Wed and Thu as the ridge re-establishes across the region. In the Gulf of California, gentle to moderate SE to S winds will prevail. Fresh to strong northerly winds are forecast to continue in the Gulf of Tehuantepec, and downwind to about 14N through Tue night into the early Wed morning. Seas there are forecast to reach 8 ft today. An area of low pressure is expected to form a few hundred miles south of eastern Mexico in a few days. Some development of this system is possible later this week while it moves west-northwestward. This could bring fresh to strong east to southeast winds and building seas to the outer offshore waters of the Mexican states of Oaxaca and Chiapas and waters downwind of the Tehuantepec region. OFFSHORE WATERS WITHIN 250 NM OF CENTRAL AMERICA, COLOMBIA, AND WITHIN 750 NM OF ECUADOR... Fresh to strong northeast to east winds are over and downwind of the Gulf of Papagayo to about 89W. Gentle to moderate winds are elsewhere north of the monsoon trough while gentle to moderate south to southwest winds are south of the monsoon trough. Seas are generally 4-6 ft, except 6-8 ft downwind of the Gulf of Papagayo to about 89W. For the forecast, gentle to moderate winds will remain across the region through Tue, with slight to moderate seas. Winds south of the monsoon trough will increase to fresh by mid-week and continue through the end of the week as broad low pressure forms to the south-southeast of the Gulf of Tehuantepec region. Winds will pulse fresh to strong mainly at night downwind of the Papagayo region through mid-week with seas building to 9 or 10 ft by Wed night. REMAINDER OF THE AREA... See the Special Features section for more information on both Tropical Storm Frank and on Tropical Depression Georgette. A ridge dominates the NW corner of the forecast region where mainly moderate NE winds are noted per satellite derived wind data. Seas are in the 4-6 ft range based on altimeter data. For the forecast, mainly moderate or weaker winds are expected across the area for the next few days outside of Frank and Georgette. Winds and seas associated with Frank will continue to affect mainly the waters east of 125W over the next few days as the tropical cyclone moves northwestward. The leading edge of 8 ft seas associated with Frank is currently reaching near 26N. As Frank progresses northward, the edge of the 8 ft seas will reach 30N by Tue night. Long-period southeast to south swell over the far southern waters, roughly between 108W-120W, will decay by this evening. $$ AKR
