{"msg": "735\nAXPZ20 KNHC 300319\nTWDEP \nTropical Weather Discussion\nNWS National Hurricane Center Miami FL\n0405 UTC Fri Oct 30 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\n0230 UTC.\n...SPECIAL FEATURES...\nThe remnants of Vance are centered near 20.7N 107.7W at 30/0300 \nUTC, moving north-northeast at 7 kt. Estimated minimum central \npressure is 1008 mb. Maximum sustained wind speed is 25 kt with \ngusts to 35 kt. Seas to 10 ft are expected in the area of highest\nwinds. Swells generated by Vance's remnants will affect coastal \nportions of southwestern and west- central Mexico, as well as the\nsouthern portion of the Baja California Peninsula, during the \nnext day or so. These swells are likely to cause life-threatening\nsurf and rip current conditions. Please consult products from \nyour local weather office for details.\nPlease read the latest HIGH SEAS FORECAST issued \nby the National Hurricane Center at website - \nhttps://www.nhc.noaa.gov/text/MIAHSFEP2.shtml and the latest \nVance NHC Forecast/Advisory and Public Advisory at \nwww.hurricanes.gov for more details.\n...INTERTROPICAL CONVERGENCE ZONE/MONSOON TROUGH...\nThe monsoon trough extends from 08N78W to 04N93W. The ITCZ\ncontinues from that point to 05N123W. A 1011 mb low is near\n06N128W. Another 1011 mb low is analyzed near 09N138W. Scattered\nmoderate convection is noted along the ITCZ, and from 05N 11N \nand W of 121W. \n...OFFSHORE WATERS WITHIN 250 NM OF MEXICO...\nPlease see the Special Features section above for information on\nTropical Depression Vance near the southern tip of Baja \nCalifornia Sur.\nAside from Vance, fresh to moderate N to NE gap winds are\noccurring over the Gulf of Tehuantepec with seas 6-8 ft. \nElsewhere, winds are moderate or weaker with 5-7 ft over the \nPacific waters, 2-4 ft over the N and central Gulf of \nCalifornia.\nFor the forecast, the remnants of Vance will dissipate Fri \nmorning. Fresh to locally strong N gap winds over the Gulf of \nTehuantepec will continue through early next week and diminish by\nMon night. A developing extratropical cyclone should move into \nthe waters west of the Baja California peninsula and over the N \nGulf of California Sat night into Sun with fresh to strong SE to \nSW winds. Fresh NW winds should occur over the Gulf of California\non Mon and Tue in the wake of the extratropical cyclone. \n...OFFSHORE WATERS WITHIN 250 NM OF CENTRAL AMERICA, COLOMBIA, \nAND WITHIN 750 NM OF ECUADOR...\nFresh NE to E gap winds are occurring over the Gulf of Papagayo \nregion. Elsewhere, winds are moderate or weaker. Seas are 4-6 \nft. Scattered moderate convection is also occurring from 03N-08N\neast of 88W.\nFor the forecast, fresh to locally strong NE to E gap winds over\nthe Gulf of Papagayo region should continue through Mon. Fresh N\nwinds over the Gulf of Panama should continue through tomorrow \nbefore weakening on Sat. Large, long-period SW swell will reach \nthe equatorial waters tomorrow before diminishing on Sun. \n...REMAINDER OF THE AREA...\nA 1011 mb low is centered near 27N136W with a trough extending \nsouthwestward to 18N140W. Winds north of the low are E fresh with\nseas to 8 ft. Elsewhere, the pressure gradient between weak \nridging north of our waters and lower pressure over the monsoon \ntrough is forcing only moderate or weaker trades across the \nforecast waters. Large, long-period SW swell is reaching \nnorthward across the equator to 04N between 108W-128W. Elsewhere \nseas are 4-7 ft.\nFor the forecast, the low will become an extratropical cyclone \nby tomorrow morning and then move slowly eastward. By Fri night, \nfresh to strong S to SW winds will develop south of a warm front \nand fresh to strong N to NE winds should occur north of a cold \nfront. The system should move over the offshore zones west of the\nBaja California peninsula on Sun with winds and seas diminishing\nby Sun night.\n", "title": "Eastern Pacific Tropical Weather Discussion", "id": "1223098300938944514", "issued": "2026-10-30T04:05:00Z", "wmo": "AXPZ20", "source": "NOAA/NWS National Hurricane Center, received via the National Weather Wire Service", "page": "https://hurricane.terrapin.com/text/1223098300938944514"}
