000 AXPZ20 KNHC 222139 TWDEP Tropical Weather Discussion NWS National Hurricane Center Miami FL 2205 UTC Wed Jun 22 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 1800 UTC surface analysis and satellite imagery through 2100 UTC. ...SPECIAL FEATURES... Tropical Storm Celia is centered near 13.8N 104.2W at 22/2100 UTC moving WNW at 7 kt. Estimated minimum central pressure is 1001 mb. Maximum sustained wind speed is 45 kt with gusts to 55 kt. Northeast winds aloft are keeping numerous strong convection within 150 nm in the southwest semicircle of the center of Celia. Seas are reaching as high as 16 ft near the center of Celia. Celia should maintain a general west- northwestward, reaching minimal hurricane strength by late Thu, then move to near Socorro Island by Sat. Celia will start to weaken as it moves past Clarion Island by early Sun. Please read the latest NHC Public Advisory at https://www.nhc.noaa.gov/text/MIATCPEP3.shtml and Forecast/ Advisory at https://www.nhc.noaa.gov/text/MIATCMEP3.shtml for more details. ...TROPICAL WAVES... A tropical wave has its axis along 96W north of 08N to the southern Bay of Campeche. It is moving westward at 5-10 kt. Scattered showers and thunderstorms are noted from 08N to 10N between 95W and 97W. ...INTERTROPICAL CONVERGENCE ZONE/MONSOON TROUGH... Segments the monsoon trough extend from 09N84W to 10N96W, and from 13N113W to 07N125W. The ITCZ extends from 07N125W to beyond 10N140W. Scattered moderate convection is noted from 08N to 10N between 85W and 87W. OFFSHORE WATERS WITHIN 250 NM OF MEXICO... Please see the Special Features section above for details on Tropical Depression Celia currently located about 270 nm south- southwest of Zihuatanejo, Mexico. East of Celia, fresh N gap winds are initiating into the Gulf of Tehuantepec, likely due to a slight tighter pressure gradient as higher pressure builds over the Gulf of Mexico. Gentle to moderate winds and slight to moderate seas are noted elsewhere across Mexican offshore waters outside of a 240 nm radii of Celia. For the forecast, swells will increase along the southwestern coast of Mexico today and spread northward along the coast through Thu, reaching the southern portions of the Baja California peninsula by Thu and into Thu night. Fresh to strong winds are expected to develop across the Gulf of Tehuantepec region late tonight then gradually diminish through Thu night into Fri. OFFSHORE WATERS WITHIN 250 NM OF CENTRAL AMERICA, COLOMBIA, AND WITHIN 750 NM OF ECUADOR... Moderate to fresh winds persist across the Gulf of Papagayo. Outside of that, light to gentle winds are noted across the Central American and Colombian offshore waters. Moderate to locally fresh southerly winds are noted across the Ecuador and Galapagos Island offshore waters. Seas are 4-6 ft across the area within southerly swell. For the forecast, winds in the Gulf of Papagayo will pulse to fresh through Thu night and become moderate into early next week. Meanwhile, light to gentle winds will prevail across the Central American offshore waters north of 09N through the rest of the week. Moderate winds will lift northward later today into the Costa Rica and Panama offshore waters. Expect moderate to locally fresh winds continuing south of 09N through Fri. REMAINDER OF THE AREA... A surface ridge extends from 1033 mb high pressure centered near 41N140W southeastward to about 20N120W. Swell in excess of 8 ft in impacting the waters north of 28N and west of 135W currently. The remnant low of Blas is centered near 19N117W, with an estimated pressure of 1010 mb and no shower or thunderstorm activity near the center. Fresh trade winds are evident into the deep tropics from 10N to 12N west of 135W related to a weak trough that has recently dissipated near 140W. A recent altimeter pass indicted seas near 8 ft near 09N140W in this area. Farther south, SW swell to 8 ft is moving across the equator and reaching as far north as 02N. Elsewhere, outside of the immediate area of Celia, gentle to moderate winds and moderate seas persist. For the forecast, mostly moderate winds will persist outside of the area impacted by Celia as the ridge to the north weakens. The northwest swell impacting the waters north of 28N will decay as it propagates westward to 140W and subside by Fri morning.Long- period primarily southwest swell just south of the Equator will subside overnight into Thu morning. $$ Christensen
