{"msg": "655\nAXPZ20 KNHC 292048\nTWDEP\nTropical Weather Discussion\nNWS National Hurricane Center Miami FL\n2205 UTC Thu Oct 29 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...SPECIAL FEATURES...\nTropical Depression Vance is centered near 22.3N 108.6W at\n29/2100 UTC, moving north at 6 kt. Estimated minimum central\npressure is 1008 mb. Maximum sustained wind speed is 30 kt with\ngusts to 40 kt. Peak seas are currently around 11-12 ft. \nScattered moderate to isolated strong convection is occurring \nfrom 23N-25N east of 108W. The motion to the north motion is  \nexpected to continue until Vance dissipates tonight or early \nFriday. Weakening is forecast, and Vance is expected to become \na post-tropical remnant low this evening. Swells generated by \nVance will affect coastal portions of southwestern and west-\ncentral Mexico, as well as the southern portion of the Baja \nCalifornia Peninsula, during the next day or so. These swells are\nlikely to cause life-threatening surf and rip current \nconditions. Please consult products from your local weather \noffice. Please read the latest HIGH SEAS FORECAST issued by the \nNational Hurricane Center at website \n- https://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 coastal Costa Rica near 10N84W \nto 04N100W to beyond 08N140W. Scattered moderate and isolated \nstrong convection is noted south of 07N between 120W-131W. \nScattered moderate convection is also occurring from 03N-08N\neast of 88W and from 03N-08N between 98W-112W and from 08N-10N\nwest of 133W. \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, Tropical Depression Vance will become a \nremnant low and move to 23.3N 108.7W at the entrance to the Gulf \nof California Fri morning, and dissipate Fri afternoon. Fresh to \nlocally strong N gap winds over the Gulf of Tehuantepec will \ncontinue through early next week and diminish by Mon night. A \ndeveloping extratropical cyclone should move into the waters west\nof the Baja California peninsula and over the N Gulf of \nCalifornia Sat night into Sun with fresh to strong SE to SW \nwinds. Looking ahead, fresh NW winds should occur over the Gulf \nof California on Mon and Tue in the wake of the extratropical \ncyclone. \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 1012 mb low is centered near 27N136W with a trough extending\nnorthwestward to 39N140W and southwestward to 22N140W. Winds\nnorth of the low are E fresh with seas to 8 ft. Elsewhere, the \npressure gradient between weak ridging north of our waters and \nlower pressure over the monsoon trough is forcing only moderate \nor weaker trades across the forecast waters. Large, long-period \nSW swell is reaching northward across the equator to 04N between\n108W-128W. Elsewhere seas are 4-7 ft.\nFor the forecast, the weak low will become an extratropical \ncyclone by tomorrow morning and then move slowly eastward. By \nFri night, fresh to strong S to SW winds will develop south of a \nwarm front and fresh to strong N to NE winds should occur north \nof a cold front. The system should move over the offshore zones \nwest of the Baja California peninsula on Sun with winds and seas \ndiminishing by Sun night.\n", "title": "Eastern Pacific Tropical Weather Discussion", "id": "1223021523833290754", "issued": "2026-10-29T22:05:00Z", "wmo": "AXPZ20", "source": "NOAA/NWS National Hurricane Center, received via the National Weather Wire Service", "page": "https://hurricane.terrapin.com/text/1223021523833290754"}
