{"msg": "886\nAXPZ20 KNHC 100322\nTWDEP \nTropical Weather Discussion\nNWS National Hurricane Center Miami FL\n0405 UTC Tue Nov 10 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 0000 UTC surface analysis and satellite imagery through\n0255 UTC.\n...INTERTROPICAL CONVERGENCE ZONE/MONSOON TROUGH...\nThe monsoon trough extends from 08N78W to a 1010 mb low pres near\n10N92W to 08N95W. The ITCZ stretches from 08N95W to 06N110W and\nto 13N127W. The monsoon trough resumes from 08N132W to beyond\n06N140W. Scattered moderate to isolated strong convection is\nobserved south of 15N and west of 100W.\n...OFFSHORE WATERS WITHIN 250 NM OF MEXICO...\nThe tight pressure gradient between a broad high pressure system\nover the southern United States and lower pressures in the deep \ntropics continue to support fresh to strong northerly winds and\nseas of 5-8 ft across the Gulf of Tehuantepec basin. Meanwhile,\nweak high pressure dominates the remainder of the Mexican offshore\nwaters sustaining moderate or weaker winds. Long-period NW swell\nis producing seas of 7-11 ft in the offshore waters of Baja \nCalifornia, with the highest seas occurring west of Guadalupe \nisland. Elsewhere, slight to moderate seas prevail.\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 \nCalifornia on Fri, associated with a frontal system, with yet \nlarger NW swell arriving Sat.\n...OFFSHORE WATERS WITHIN 250 NM OF CENTRAL AMERICA, COLOMBIA, \nAND WITHIN 750 NM OF ECUADOR...\nHigh pressure centered north of the the Caribbean supports\nmoderate to fresh easterly trade winds and moderate seas in the\nGulf of Papagayo region. Moderate northerly winds and seas of 2-4\nft are occurring in the Gulf of Panama. Elsewhere, moderate or\nweaker winds and moderate seas prevail.\nFor the forecast, fresh to locally strong easterly trade winds \nwill funnel across the Papagayo region and extend to 90W through \nWed night, then diminish into the weekend. Moderate to locally \nfresh winds will pulse in the western Gulf of Panama through Wed \nmorning. Otherwise, moderate or weaker winds, and moderate seas \nin mixed SW to W swell, will prevail.\n...REMAINDER OF THE AREA...\nA broad subtropical ridge centered on a 1024 mb high near \n30N136W dominates the eastern Pacific basin, and supports \nmoderate to fresh easterly winds north of 10N, and west of 120W.\nSeas N of 10N and W of 120W are 8 to 11 ft in NW swell. A broad \nsurface trough from 07N131W to 15N126W is producing scattered\nmoderate to isolated strong convection from 07N to 16N and \nbetween 115W and 133W, where fresh to locally strong winds \nprevail. Meanwhile, moderate to fresh SE winds and seas to 10 ft\nare occurring south of 03N between 100W and 120W. Elsewhere, \nmoderate or weaker winds and moderate seas prevail.\nFor the forecast, high pressure will support moderate to fresh\neasterly winds and rough seas across the trade waters during the\nnext few days. New large NW swell moving into the north and \nwestern waters will reach from 10N140W to the Revillagigedo \nIslands by Tue night. The mixed swell over the equatorial waters \nwill persist for the next several days. Looking ahead, a strong \ncold front will reach our NW border at 30N140W by midday Wed, \nbringing with it fresh to strong NW winds and very large seas in \nNW swell north of 20N through the end of the week. Even larger \nreinforcing NW swell may arrive Fri afternoon or evening to the \nNW waters, possibly in excess of 20 ft.\n", "title": "Eastern Pacific Tropical Weather Discussion", "id": "1226213160783216643", "issued": "2026-11-10T04:05:00Z", "wmo": "AXPZ20", "source": "NOAA/NWS National Hurricane Center, received via the National Weather Wire Service", "page": "https://hurricane.terrapin.com/text/1226213160783216643"}
