{"msg": "121\nAXPZ20 KNHC 092052\nTWDEP \nTropical Weather Discussion\nNWS National Hurricane Center Miami FL\n2205 UTC Mon Nov 9 2026\nTropical Weather Discussion for the eastern Pacific Ocean from\n03.4S to 30N, east of 120W including the Gulf of California, and\nfrom the Equator to 30N, between 120W and 140W. The following\ninformation is based on satellite imagery, weather observations,\nradar, and meteorological analysis.\nBased on 1800 UTC surface analysis and satellite imagery through\n2030 UTC.\n...INTERTROPICAL CONVERGENCE ZONE/MONSOON TROUGH...\nThe monsoon trough extends from 11N73W to 09N89W to 07.5N92W. \nThe ITCZ stretches from 07.5N92W to 04.5N108W to 09.5N121W. \nScattered moderate convection is noted south of 00N E of 93W. \nScattered moderate isolated strong convection is observed from \n02N to 06N between 98W and 110W and south of 03N between 123W and\n132W. Scattered to numerous moderate isolated strong convection \nis noted from 08N to 15N and between 115W and 134W, and from 00N\nto 10.5N west of 136W.\n...OFFSHORE WATERS WITHIN 250 NM OF MEXICO...\nHigh pressure remains centered west of the area along 138W, with\na ridge extending east and then southeastward into the area \nwaters near the Revillagigedo Islands. This pattern is \nsupporting moderate northerly winds across the Baja Norte waters\nand gentle winds south of Punta Eugenia. Seas are 6-8 ft in NW \nswell across the Baja waters, except to 9 to 10 ft in new NW\nswell northwest of Isla Guadalupe. Moderate to locally fresh  \nnortherly winds generally prevail across the far northern Gulf \nof California, with winds gentle elsewhere. Seas in the NW Gulf\nare 3 to 4 ft, and 3 ft or less elsewhere. Light to gentle \nwinds prevail across the remainder of the Mexican offshore \nwaters from Cabo Corrientes to Puerto Angel. Recent satellite \naltimeter satellite data showed seas of 4 to 7 ft in mixed NW and\nSW swell across this area. High pressure extending across the \nGulf of America continues to force fresh to strong northerly \nwinds and seas of to 8 ft ft across the Gulf of Tehuantepec and \nextending southward to 14N. \nFor the forecast, fresh northerly winds and rough seas around 8 \nft will pulse to strong at night across the Gulf of Tehuantepec \nthrough The remainder of the week. Strong gap winds to near gale\nforce are expected Tue night. Rough seas in NW swell will\ncontinue across the Baja offshore waters through Tue as new swell\narrives tonight, then begin to diminish Tue night through Thu.  \nLooking ahead, fresh to strong winds and rough seas approaching \n12 ft are expected to reach the offshore waters of Baja California\non Fri, associated with a frontal system, with yet larger NW \nswell arriving Sat.\n...OFFSHORE WATERS WITHIN 250 NM OF CENTRAL AMERICA, COLOMBIA, \nAND WITHIN 750 NM OF ECUADOR...\nA weakening 1010 mb low pressure, Invest EP96, is located near\n10N91W, or about 240 nm south of Chiapas, Mexico. Scattered \nlight showers are occurring within 75 nm across the northeastern\nsemicircle of this system, and continue to diminish in coverage \nand intensity. Fresh to locally strong NE to E winds and seas to \n8 ft prevail within 120 nm N of the center. Strong wind shear \nwill continue to weaken this low, and it is expected to open up\ninto a trough tonight. To the east of the low, fresh easterly \ngap winds extend from the Papagayo region to near the low, where \nseas are 4 to 6 ft. Strong convection across the Central American  \nwaters and coasts of the past few days has ended. Elsewhere, \nwinds are moderate or weaker with seas 4-6 ft in mixed SW and W \nswell. Clusters of scattered showers and isolated thunderstorms \nare seen from the equator southward to 04S, and east of 93W and \nthe Galapagos Islands to the coast of Ecuador.\nFor the forecast, the low center, EP96, will move westward over\nthe next few days, while weakening to a trough tonight. The \nthreat of widespread heavy rainfall associated with that system \nappears to have ended. Meanwhile, fresh to locally strong \neasterly trade winds will funnel across the Papagayo region and \nextend to 90W through Wed night then weaken into the weekend. \nModerate to locally fresh winds will pulse in the western Gulf \nof Panama through Wed morning. Otherwise, moderate or weaker \nwinds, and moderate seas in mixed SW to W swell, will prevail.\n...REMAINDER OF THE AREA...\nA broad subtropical ridge centered on a 1023 mb high near \n30N138W dominates the eastern Pacific basin, and supports \nmoderate to fresh easterly winds between 10N and 25N, and west \nof 120W. Seas N of 10N and W of 120W are 8 to 12 ft in NW swell. \nA broad surface trough from 10N132W to 16N119W is producing \nscattered to numerous moderate isolated strong convection from \n08N to 15N and between 115W and 134W, where fresh winds prevail.\nMeanwhile, moderate to fresh SE winds and seas to 9 ft are \noccurring south of 03N between 100W and 120W. Elsewhere, \nmoderate or weaker winds and moderate seas prevail.\nFor the forecast, the surface ridge will amplify some, increasing\nthe trades to fresh from 10N-25N west of 125W tonight into Wed.\nNew large NW swell moving into the north and western waters today \nwill reach from 10N140W to the Revillagigedo Islands by Tue \nnight. The mixed swell over the equatorial waters will persist \nfor the next several days. Looking ahead, a strong cold front \nwill reach our NW border at 30N140W by midday Wed, bringing with\nit fresh to strong NW winds and very large seas in NW swell north\nof 20N through the end of the week. Even larger reinforcing NW \nswell may arrive Fri afternoon or evening to the NW waters,\npossibly in excess of 20 ft.\n", "title": "Eastern Pacific Tropical Weather Discussion", "id": "1226136538003800067", "issued": "2026-11-09T22:05:00Z", "wmo": "AXPZ20", "source": "NOAA/NWS National Hurricane Center, received via the National Weather Wire Service", "page": "https://hurricane.terrapin.com/text/1226136538003800067"}
