000 AXPZ20 KNHC 081622 TWDEP Tropical Weather Discussion NWS National Hurricane Center Miami FL 1605 UTC Tue Feb 8 2022...Corrected 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. ...Corrected Remainder of Area Section... Based on 1200 UTC surface analysis and satellite imagery through 1500 UTC. ...SPECIAL FEATURES... Gulf of Tehuantepec Gale Warning: A tight pressure gradient between 1029 mb high pressure over eastern Mexico and the equatorial trough in the eastern Pacific is supporting gale force winds over the Tehuantepec region. Northerly winds are peaking today at 40-45 kt. Seas will build to 15-17 ft by midday today. Winds will begin diminishing Wed morning, and then drop below gale-force late Wed afternoon or early Wed evening. Please read the latest High Seas Forecast issued by the National Hurricane Center at website https://www.nhc.noaa.gov/text/MIAHSFEP2.shtml for further details. ...INTERTROPICAL CONVERGENCE ZONE/MONSOON TROUGH... A surface trough extends from 11N86W to 06N94W. The ITCZ continues from 06N94W to 06N106W to 10N117W to 07N130W to 06N140W. Scattered moderate convection is noted from 10N to 13N between 112W and 120W, and from 07N to 10N between 122W and 134W. OFFSHORE WATERS WITHIN 250 NM OF MEXICO Please see the Special Features section above for information on the Gulf of Tehuantepec gale-force gap wind event. Fresh NW winds are likely occurring in the Gulf of California with seas of 3 to 5 ft. Gale force N winds of 35-45 kt are likely occurring in the Gulf of Tehuantepec, north of 13.5N, where seas are likely 12-16 ft. Gentle to moderate N winds are noted west of Baja California and off Cabo Corrientes, where seas are likely 4-6 ft. Light to gentle winds are elsewhere with 3-5 ft seas. For the forecast, the tight pressure gradient between high pressure over Mexico and the equatorial trough in the EPAC waters will continue to support gale-force winds in the Gulf of Tehuantepec through Wed. Elsewhere, fresh NW winds over the Gulf of California will diminish to moderate this afternoon. Then, moderate winds will continue through Wed. Moderate winds west of Baja and off Cabo Corrientes will diminish to gentle late this afternoon. Looking ahead, the next gale force event in the Gulf of Tehuantepec is expected to begin over the weekend. OFFSHORE WATERS WITHIN 250 NM OF CENTRAL AMERICA, COLOMBIA, and WITHIN 750 NM OF ECUADOR Moderate to fresh NE winds are in the Papagayo region with seas to 5 ft. Moderate N winds are noted in the Gulf of Panama with seas of 4-5 ft. Seas are 6-8 ft now and continue to build well offshore of Guatemala due to N swell from a Gulf of Tehuantepec gap wind gale event. Light to gentle variable winds prevail elsewhere with seas in the 3-5 ft range. For the forecast, moderate winds in the Papagayo region should continue through tonight. Then, pulsing fresh to strong winds will resume in the Papagayo region Wed morning and continue through the end of the week and into the weekend. Pulsing moderate to fresh N winds are expected in the Gulf of Panama each night through Fri night. Light to gentle winds will prevail elsewhere. Swell generated from the gale-force gap wind event in the Gulf of Tehuantepec is forecast to produce large seas of 7 to 11 ft over the Guatemala and El Salvador offshore waters this afternoon through Wed. REMAINDER OF THE AREA A large upper-level trough is just west of 140W. Upper-level diffluence east of the upper-trough is supporting scattered moderate convection from 15.5N to 23N between 136W and 140W. Ridging from a 1037 mb high pressure north of the area near 41N135W extends across the northern portions of the forecast waters. The pressure gradient between the high pressure and the ITCZ is producing fresh to locally strong E winds roughly from 17N to 22N and W of 132W. Fresh NE winds are from 12N to 19N between 120W and 132W. Seas of 8-10 ft are evident west of 125W north of 12N. This area is under the influence of moderate NW swell. Mainly gentle to moderate winds and seas of 6-7 ft are present elsewhere over the area. For the forecast, high pressure will remain centered north of the area through early Wed. This should maintain an area of fresh NE trades over the waters from 10N to 25N and W of 120W through Wed morning. Thereafter, the high will retreat farther north, diminishing the gradient, and decreasing the winds. A surface trough is expected to form Thu along 134W from 14N-20N. This trough will move E, producing fresh to strong winds through Thu and Fri. $$ Hagen
