{"msg": "458\nAXPZ20 KNHC 312133\nTWDEP \nTropical Weather Discussion\nNWS National Hurricane Center Miami FL\n2205 UTC Sat Oct 31 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\n2200 UTC.\n...INTERTROPICAL CONVERGENCE ZONE/MONSOON TROUGH...\nThe monsoon trough extends from 10N85W to 01N133W. Scattered \nmoderate convection is depicted S of 11N and E of 135W. Scattered\nmoderate to strong convection is S of 07N between 100W and 115W.\n...OFFSHORE WATERS WITHIN 250 NM OF MEXICO...\nFresh to strong N to NE gap winds are occurring over the Gulf of\nTehuantepec with seas of 5-8 ft. The pressure gradient between \nhigher pressures over Mexico and a trough along the Gulf of \nCalifornia is supporting moderate to locally fresh S to SE winds\nover southern portions of the Gulf. Elsewhere, winds are \nmoderate or weaker with 4-6 ft over the Pacific waters, 2-5 ft \nover the N and central Gulf of California.\nFor the forecast, fresh to strong N gap winds over the Gulf of \nTehuantepec will continue through early next week, diminishing \nMon night. A developing extratropical cyclone should move into \nthe waters west of the Baja California peninsula and over the N \nGulf of California tonight into Sun with strong to near-gale SE \nto SW winds and seas to 8 ft. Fresh to strong SW winds along \nwith seas of 5-6 ft should occur over the Gulf of California on \nSun in the wake of the extratropical cyclone. Moderate or weaker \nwinds will likely return to the offshore waters Sun into Mon. \n...OFFSHORE WATERS WITHIN 250 NM OF CENTRAL AMERICA, COLOMBIA, \nAND WITHIN 750 NM OF ECUADOR...\nFresh to strong NE to E gap winds are occurring over the Gulf of\nPapagayo region with seas 5 to 7 ft. Moderate N winds along with\nseas of 4 to 6 ft are present over the Gulf of Panama. \nElsewhere, winds are moderate or weaker. Scattered moderate \nconvection is occurring S of 08N east of 93W.\nFor the forecast, fresh to strong NE to E gap winds over the \nGulf of Papagayo region will continue through Mon. Fresh N winds\nover the Gulf of Panama should continue today before weakening \non Sat. Large, long-period SW swell has reached the equatorial \nwaters, and will gradually diminish on Sun. \n...REMAINDER OF THE AREA...\nA 1006 mb low is centered near 26N125W, with a cold front \nextending southwestward to 15N135W, and a warm front extending \nfrom the low to 18N134W. Fresh to strong winds in counter-\nclockwise flow surrounds the low from 20N to 30N between 119W and\n129W, with seas to 8 ft. Moderate to fresh southwest winds are \nfound farther southwest along the cold front. Elsewhere, the \npressure gradient between weak ridging north of the region and \nlower pressure near the monsoon trough is supporting only \nmoderate or weaker trades across the forecast waters. Large, \nlong-period SW swell is expanding northward across the equator to\n09N between 87W-134W. Elsewhere, seas are 4-7 ft.\nFor the forecast, the low will become a strong extratropical \ncyclone and then move slowly eastward through the weekend. The \nsystem should move over the offshore zones west of the Baja \nCalifornia peninsula on Sun with winds and seas diminishing by \nSun night.\n", "title": "Eastern Pacific Tropical Weather Discussion", "id": "1223596513831649283", "issued": "2026-10-31T22:05:00Z", "wmo": "AXPZ20", "source": "NOAA/NWS National Hurricane Center, received via the National Weather Wire Service", "page": "https://hurricane.terrapin.com/text/1223596513831649283"}
