{"msg": "919\nAXPZ20 KNHC 110902\nTWDEP \nTropical Weather Discussion\nNWS National Hurricane Center Miami FL\n1005 UTC Wed Nov 11 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 0600 UTC surface analysis and satellite imagery through\n0830 UTC.\n...INTERTROPICAL CONVERGENCE ZONE/MONSOON TROUGH...\nThe monsoon trough extends from 07N78W to 04N91W. The ITCZ \nstretches from 04N91W to 05N110W and to 07N134W. Scattered \nmoderate to isolated strong convection is observed south of 15N \nand west of 103W.\n...OFFSHORE WATERS WITHIN 250 NM OF MEXICO...\nHigh pressure north of the area continues to support fresh to\nnear gale-force northerly winds and seas of 5-8 ft across the \nGulf of Tehuantepec, spreading downstream to 13N. Meanwhile, \nbroad ridging extends southeastward across the Baja California \nwaters to the Revillagigedo Islands, allowing for moderate or \nlighter winds in the rest of the Mexican offshore waters. Long-\nperiod NW swell is producing seas of 8-11 ft in the offshore \nwaters of Baja California. Elsewhere, slight to moderate seas \nprevail.\nFor the forecast, fresh northerly winds and rough seas around 8 \nft will pulse to strong to locally near gale-force at night \nacross the Gulf of Tehuantepec through the remainder of the week. \nRough seas in NW swell in the Baja California waters will \ndiminish through Thu. Looking ahead, fresh winds and rough seas \napproaching 12 ft are expected to reach the offshore waters of \nBaja California by early Fri, associated with a frontal system. \nMeanwhile, a larger NW swell arriving Sat will produce high seas\nto 20 ft. Rough seas will reach all the way to near 100W by \nearly next week, while additional and reinforcing NW swell sets \ncontinue to arrive. The next Tehuantepec gap wind event may occur\nearly next week.\n...OFFSHORE WATERS WITHIN 250 NM OF CENTRAL AMERICA, COLOMBIA, \nAND WITHIN 750 NM OF ECUADOR...\nA broad subtropical ridge centered over the Gulf of America and\nthe western Atlantic extends southward and is supporting moderate\nto locally strong easterly trade winds and seas of 4-6 ft across the \nGulf of Papagayo region. Farther east, moderate to locally fresh \nnortherly winds and seas of 2-4 ft are found in the Gulf of Panama. \nElsewhere, moderate or weaker winds and moderate seas are prevalent.\nFor the forecast, fresh to locally strong easterly trade winds \nwill funnel across the Papagayo region and extend to 90W through \nthis evening, then diminish for the end of the week into the \nweekend. Moderate to fresh winds may return to the Papagayo \nregion by the end of the weekend into early next week. Moderate \nto locally fresh winds will pulse in the Gulf of Panama through \nthis morning, then again by the end of the weekend. Otherwise, \nmoderate or weaker winds and moderate seas in merging SW and NW \nswell will prevail, except locally rough SSW of the Galapagos \nIslands through the week.\n...REMAINDER OF THE AREA...\nA recent scatterometer satellite pass captured a broad low pressure \narea near 06N138W and a surface trough is analyzed northward from \nthis low. Scattered showers and isolated thunderstorms are occurring \nsouth of 12N and west of 133W, with the strongest convection noted \nnorth of the low. The satellite-derived wind data also show strong \nto near gale-force winds associated with the strongest convection.\nThe rest of the tropical eastern Pacific waters is under a broad\nsubtropical ridge that extends from the western United States to\nthe western waters. The pressure gradient between this ridge and\nlower pressures in the deep tropics supports fresh to locally \nstrong easterly trade winds and seas of 8-11 ft from 10N to 23N \nand west of 120W. Moderate to fresh SE winds and rough seas are \nfound south of 03N and between 100W and 125W. Elsewhere, moderate\nor weaker winds and seas of 5-8 ft prevail.\nFor the forecast, high pressure combined with troughing over the\nW-central waters will support moderate to locally strong \neasterly winds and rough seas across the trade waters through the\nrest of the week. A strong cold front will reach our NW border \nat 30N140W late this morning, bringing with it fresh to strong \nwinds on either side of the front, and very large seas in NW \nswell north of 20N through the end of the week. Even larger \nreinforcing NW swell may arrive Fri afternoon to the NW waters, \npossibly reaching 25 ft. This set of swell with seas of 8 ft or \ngreater will cover the waters N of 05N and W of 110W by late Sat \nnight, then covering all of the waters W of 105W. Yet another set\nof large swell will arrive Sun. The mixed swell over the equatorial\nwaters will persist for the next several days.\n", "title": "Eastern Pacific Tropical Weather Discussion", "id": "1226563102462083074", "issued": "2026-11-11T10:05:00Z", "wmo": "AXPZ20", "source": "NOAA/NWS National Hurricane Center, received via the National Weather Wire Service", "page": "https://hurricane.terrapin.com/text/1226563102462083074"}
