000 AXPZ20 KNHC 132222 TWDEP Tropical Weather Discussion NWS National Hurricane Center Miami FL 2205 UTC Fri Aug 13 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 1800 UTC surface analysis and satellite imagery through 2100 UTC. ...SPECIAL FEATURES... Hurricane Linda is centered near 17.5N 112.9W at 2100 UTC moving WNW at 12 kt. Estimated minimum central pressure is 965 mb. Maximum sustained wind speed is NOW 100 kt with gusts to 120 kt, making Linda a major, category 3 hurricane. Numerous strong convection is noted with 75 nm of the center. Scattered moderate isolated strong convection is noted elsewhere within 180 nm of the center, except 240 nm across the SW quadrant. Linda is forecast to remain a major hurricane on a W-NW track through Sun, as it exits the outer offshore waters of central Mexico and passes very close to the Revillagigedo Islands. A gradual turn to the west and then west southwest is expected after Sunday, and a gradual weakening trend will ensue. Linda is expected to weaken to a tropical storm by Wednesday. 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 82W, moving W at around 10 kt. Scattered moderate to strong convection is noted from 04N to 12N between 77W and 85W. A tropical wave is along 96W, moving W at 10-15 kt. Scattered moderate to strong convection is noted from 10N to 16N between 92W and 101W. ...INTERTROPICAL CONVERGENCE ZONE/MONSOON TROUGH... The monsoon trough axis extends from the Caribbean coast of Colombia near 10.5N76.5W westward across Panama to 10N95W to 09N110W. Another segment of the monsoon trough extends from 14.5N116W TO 12.5N132W. The ITCZ continues from 12.5N132W to beyond 09N140W. Scattered moderate to strong convection is noted from 04N to 09N between 77W and 91W, and from 07N to 16N between 92W and 106W. Scattered moderate isolated strong convection is noted within 120 nm of trough and ITCZ between 119W and 138W. OFFSHORE WATERS WITHIN 250 NM OF MEXICO... Please read the Special Features section for details on Hurricane Linda. Afternoon scatterometer satellite data showed tropical storm force winds on the NE periphery of Linda moving across the extreme outer offshore waters between 111W and 113W, or about 440 nm SW of Cabo Corrientes. Seas across this area are estimated to be 12-16 ft in SE swell. Beyond the NE semicircle of Linda, winds were variable at less than 15 kt across the remaining offshore waters of Mexico. The exception to this is across the far northern Gulf of California, where southerly winds of 15 to 20 kt prevail. Active weather accompanies a tropical wave moving past the Gulf of Tehuantepec. The remnants of former tropical cyclone Kevin, a 1011 mb low center, were located well offshore near 26N125.5W. A very weak and narrow ridge prevails across the offshore waters between this low and Baja California. This is producing light and variable across the Baja offshore waters, where seas are 5-7 ft. SE swell from Linda has begun to reach the southern waters of Baja California Sur, and are building to 7-9 ft, including the entrance to the Gulf of California. Other than strong swell affecting the Baja offshore waters through the weekend, the main impacts of Hurricane Linda will be in the Revillagigedo Islands and adjacent waters through early Sat. The center of Linda will move to 18.2N 114.6W tonight, then pass just south and very near Clarion Island late tonight, before reaching 18.9N 116.9W midday Sat. Linda will continue to move west of the Revillagigedo Islands through the remainder of the weekend. The remnant low of Kevin will continue to move WNW away from the offshore waters of Baja California, dissipating this weekend. Fresh gap winds across the Gulf of Tehuantepec will pulse to strong each of the next few nights. 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 early next week, supporting scattered showers and thunderstorms across the region, associated with the next tropical wave. 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 26N125.5W. Afternoon scatterometer satellite data indicated winds have continued to diminish since yesterday with mainly moderate to fresh winds within 180 nm of the center. Peak seas are estimated to be 8 to 9 ft across the NE 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. $$ Stripling
