{"msg": "225\nAXPZ20 KNHC 020937\nTWDEP \nTropical Weather Discussion\nNWS National Hurricane Center Miami FL\n1005 UTC Wed Sep 2 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\n0930 UTC.\n...SPECIAL FEATURES...\nHurricane Karina is centered near 18.5N 131.7W at 02/0900 UTC,\nmoving west at 10 kt. Estimated minimum central pressure is 940\nmb. Maximum sustained wind speed is 125 kt with gusts to 150 kt.\nPeak seas are around 42 ft. Numerous moderate to scattered \nstrong convection is noted from 16N to 21N between 129W and 134W.\nKarina is a category 4 hurricane on the Saffir-Simpson Hurricane\nWind Scale. Some additional strengthening is possible through \nWednesday morning, followed by slow weakening over the next \nseveral days. However, Karina is likely to remain a major \nhurricane into Thursday. \nTropical Storm Marie is centered near 16.7N 111.0W at 02/0900\nUTC, moving northwest at 9 kt. Estimated minimum central\npressure is 994 mb. Maximum sustained wind speed is 55 kt with\ngusts to 65 kt. Peak seas are around 28 ft. Numerous moderate to\nscattered strong convection is noted from 09N to 21N between \n105W and 116W. Some strengthening is forecast during the next 48\nhours, and Marie is likely to become a hurricane later today. \nSwells generated by Marie will affect portions of the coast of \nsouthwest Mexico and the Baja California Peninsula for the next \nfew days and will likely spread northward to southern California \nover the weekend. These swells are likely to cause life- \nthreatening surf and rip current conditions. Please consult \nproducts from your local weather office. \nPlease read the latest HIGH SEAS FORECAST issued by the National\nHurricane Center at website - \nhttps://www.nhc.noaa.gov/text/MIAHSFEP2.shtml and the latest NHC \nTropical Weather Outlook at www.hurricanes.gov for more details.\n \n...TROPICAL WAVES...\nA tropical wave is along 90W, extending across Guatemala to 07N,\nmoving westward at 15 kt. Scattered moderate to strong \nconvection is present from 03N to 16N between 87W and 97W. \n...INTERTROPICAL CONVERGENCE ZONE/MONSOON TROUGH...\nThe monsoon trough extends from 09N85W to 08N92W to 10N101W. \nScattered moderate to strong convection is present from 01N to \n12N between 118W and 140W.\n...OFFSHORE WATERS WITHIN 250 NM OF MEXICO...\nPlease see the Special Features section for more information on \nTropical Storm Marie centered SW of Mexico.\nTropical Storm Marie is near 16.7N 111.0W at 2 AM \nPDT, and is moving northwest at 9 kt. Maximum sustained winds are\n55 kt with gusts to 65 kt, and the minimum central pressure is \n994 mb. Aside from the impacts of Tropical Storm Marie, a weak \npressure gradient across the offshore waters of Baja California \nsustains moderate or weaker winds and moderate seas. A slightly \ntighter pressure gradient in the northern Gulf of California is \nallowing for locally fresh southerly winds and slight seas. \nElsewhere, light to gentle winds and slight to moderate seas \nprevail.\nFor the forecast, Marie will strengthen to a hurricane near \n17.5N 112.1W this afternoon, move to 18.4N 113.6W Thu morning, \n19.1N 115.1W Thu afternoon, 19.7N 116.6W Fri morning, 20.2N \n118.0W Fri afternoon, and 20.8N 119.3W Sat morning. Marie will \nchange little in intensity as it moves near 22.1N 121.8W early \nSun. Elsewhere, a tighter pressure gradient will result in fresh \nto locally strong southerly winds and moderate seas in the \nnorthern Gulf of California through Fri night.\n...OFFSHORE WATERS WITHIN 250 NM OF CENTRAL AMERICA, COLOMBIA, \nAND WITHIN 750 NM OF ECUADOR...\nHigh pressure north of the area supports moderate to locally fresh\neasterly winds and moderate seas in the Gulf of Papagayo region,\nextending outward to 88W. Moderate or weaker winds and slight to\nmoderate seas prevail elsewhere.\nFor the forecast, the subtropical ridge north of the Caribbean\nwill sustain moderate to fresh easterly trade winds and moderate\nseas across the Gulf of Papagayo through the workweek. Winds may\npulse to strong speeds at night late this week into the upcoming\nweekend. Elsewhere, moderate or lighter winds and slight to \nmoderate seas will prevail.\n...REMAINDER OF THE AREA...\nPlease see the Special Features section for more information\nabout Hurricane Karina centered between Mexico and Hawaii, and \nTropical Storm Marie located southwest of Mexico.\nTropical Storm Marie is near 16.7N 111.0W at 2 AM PDT, and is\nmoving northwest at 9 kt. Maximum sustained winds are 55 kt with\ngusts to 65 kt, and the minimum central pressure is 994 mb. \nHurricane Karina is near 18.5N 131.7W at 2 AM PDT, and is moving\nwest at 10 kt. Maximum sustained winds are 125 kt with gusts to \n150 kt, and the minimum central pressure is 940 mb. Aside from \nthe impacts of Hurricane Karina and Tropical Storm Marie, \nmoderate or weaker winds and moderate seas dominate the tropical \neastern Pacific. Otherwise, a small area of cross equatorial \nswell is noted W of the Galapagos Islands producing seas to 8 \nft.\nFor the forecast, Marie will strengthen to a hurricane near \n17.5N 112.1W this afternoon, move to 18.4N 113.6W Thu morning, \n19.1N 115.1W Thu afternoon, 19.7N 116.6W Fri morning, 20.2N \n118.0W Fri afternoon, and 20.8N 119.3W Sat morning. Marie will \nchange little in intensity as it moves near 22.1N 121.8W early \nSun. Karina will move to 19.0N 133.1W this afternoon, 19.5N \n135.0W Thu morning, 19.9N 137.0W Thu afternoon, 20.4N 139.0W Fri \nmorning, 20.8N 140.8W Fri afternoon, and 21.4N 142.3W Sat \nmorning. Karina will weaken to a tropical storm near 22.9N \n144.8W early Sun.  \nElsewhere, the cross equatorial swell will remain south of 02N \nover the next few days, producing seas to 9 ft before subsiding \nlate this week.\n", "title": "Eastern Pacific Tropical Weather Discussion", "id": "1206751841775681539", "issued": "2026-09-02T10:05:00Z", "wmo": "AXPZ20", "source": "NOAA/NWS National Hurricane Center, received via the National Weather Wire Service", "page": "https://hurricane.terrapin.com/text/1206751841775681539"}
