000 AXPZ20 KNHC 140357 TWDEP Tropical Weather Discussion NWS National Hurricane Center Miami FL 0405 UTC Sat Aug 14 2021 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 0300 UTC. ...SPECIAL FEATURES... Major Hurricane Linda is centered near 17.9N 113.9W at 14/0300 UTC moving WNW at 11 kt. Estimated minimum central pressure is 962 mb. Maximum sustained wind speed is 105 kt with gusts to 130 kt. Numerous strong convection is noted with 75 nm in the southern hemisphere of the center, and within 45 nm in the northern hemisphere. Scattered moderate isolated strong convection is noted elsewhere within 150 nm in the southern hemisphere of the center. The eyewall of Linda is approximately 30 nm from Clarion Island. The center of Linda will pass close to Clarion Island overnight, and remain a major hurricane through late Sat as it continues to move west. Linda will gradually weaken thereafter, but only to tropical storm strength by mid week as it reaches 135W. 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 83W, moving W at around 10 kt. Scattered moderate to strong convection is noted from 06N to 09N between 83W and 85W. A tropical wave is along 97W, moving W at 10-15 kt. Scattered moderate to strong convection is noted from 10N to 14N between 95W and 98W. ...INTERTROPICAL CONVERGENCE ZONE/MONSOON TROUGH... Segments of the monsoon trough axis extends from 09N84W to 10N95W to 09N100W to 09N110W, and from 14N120W to 12N135W. The ITCZ continues from 12N135W to beyond 08N140W. In addition to the convection described above in the Special Features and Tropical Wave sections, scattered moderate to isolated strong convection is evident from 10N to 14N between 100W and 105W. Scattered moderate convection is noted from 10N to 14N between 130w and 135W. OFFSHORE WATERS WITHIN 250 NM OF MEXICO... Please read the Special Features section for details on Hurricane Linda. A recent altimeter satellite pass indicated seas in excess of 10 ft between Los Cabos and Socorro Island, associated with swell generated from Linda. Outside of the hurricane conditions in the Revillagigedo Islands region, mostly gentle to moderate winds are noted elsewhere over Mexican offshore waters north of 20N, with 5 to 8 ft seas over open waters. Farther south, fresh to strong gap winds are likely ongoing across the Gulf of Tehuantepec, between tropical waves moving through Central America and southern Mexico. Gentle winds persist elsewhere off southern Mexico with 5 to 7 ft seas primarily in SW swell. For the forecast, Linda will move near Clarion Island overnight, reaching 18.5N 115.6W Sat morning, 19.1N 117.8W Sat evening, and change little in intensity as it moves farther to the west of the area through early next week. Elsewhere, fresh gap winds across the Gulf of Tehuantepec will continue to pulse to locally strong tonight through Sat night. Swells generated by Linda are expected to affect portions of the coast of southwestern Mexico and the southern and western coast of Baja California Sur over the next few days. These swells are likely to cause life-threatening surf and rip current conditions. Please consult products from your local weather office. OFFSHORE WATERS WITHIN 250 NM OF CENTRAL AMERICA, COLOMBIA, and WITHIN 750 NM OF ECUADOR... Moderate E winds are noted in the Papagayo region, with light to gentle winds elsewhere north of the monsoon trough. Moderate to locally fresh S-SW winds are south of the monsoon trough. Seas are in the 4 to 6 ft range in long period mixed swell. Mainly gentle winds will prevail north of the monsoon trough through early next week. South of the monsoon trough, mainly moderate, occasionally fresh, S to SW winds will prevail through the middle of next week, supporting scattered showers and thunderstorms across the region. New southerly swell will impact the waters offshore of Ecuador early next week. REMAINDER OF THE AREA... Please read the Special Features section for details on Hurricane Linda. The 1011 mb remnant low of Kevin is centered near 27N127W. Earlier scatterometer satellite data indicated winds have continued to diminish since yesterday with mainly moderate to fresh winds within 180 nm of the center. A recent altimeter satellite pass showed mainly 6 ft seas in the southeast of the low, but sea to 8 ft may be lingering near in the northeast quadrant. Elsewhere, weak surface ridging prevails across the remainder of the open waters. Gentle to moderate trades are noted north of the monsoon trough outside of the influence of Linda and remnants of Kevin, with moderate to fresh southerly flow south of the monsoon trough. Seas of 4 to 7 ft in mixed long period swell are noted outside of Linda and Kevin. For the forecast, the remnant low of Kevin will continue to move WNW away from the offshore waters of Baja California, dissipating to a trough during the next 24 hours. Linda is forecast to remain a hurricane through the weekend as it continues generally westward. Elsewhere, southerly swell from the southern hemisphere will cross the Equator Sun night through Tue, resulting in seas of 7 to 8 ft south of 10N between 100W and 125W. $$ Christensen
