{"msg": "521\nAXNT20 KNHC 182202\nTWDAT\nTropical Weather Discussion\nNWS National Hurricane Center Miami FL\n0015 UTC Mon Oct 19 2026\nTropical Weather Discussion for North America, Central America\nGulf of America, Caribbean Sea, northern sections of South\nAmerica, and Atlantic Ocean to the African coast from the\nEquator to 31N. The following information is based on satellite\nimagery, weather observations, radar and meteorological analysis.\nBased on 1800 UTC surface analysis and satellite imagery through \n2130 UTC.\n...SPECIAL FEATURES...\nGulf of America Gale Warning: A cold front is stalling this\nevening from the northwest coast of Cuba to the eastern Bay of\nCampeche. Scattered moderate convection is occurring within 120 nm\nsouth and 60 nm north of the boundary. Gale-force winds and very\nrough seas are present behind the front int the western Bay of\nCampeche, with fresh to strong N winds and occasional rough seas\nelsewhere N of the front. The front will remain generally\nstationary and weaken into Tue. Gales and very rough seas will \nprevail in the SW basin through tonight, with rough seas then\ncontinuing through Tue. \nAtlantic Gale Warning: The aforementioned cold front is moving\nfaster in the Atlantic, and extends this evening from 31N70W\nthrough the NW Bahamas and to the northern coast of Cuba.\nScattered moderate convection is noted up to 120 nm ahead of this\nfront, and 60 nm behind the boundary. N of the cold front, near\ngale-force northeast to north winds and very rough seas of up to\n20 ft area present, with gales occurring N of 29N between 71W and\n74W. The front will gradually slow down overnight, with gales\ncontinuing into early Mon, and very rough seas expanding \nsoutheastward into Tue. \nPlease read the latest High Seas Forecast issued by the National \nHurricane Center under AWIPS/WMO headers FZNT02 KNHC/HSFAT2 or at \nwebsite https://www.nhc.noaa.gov/text/MIAHSFAT2.shtml for further \ndetails.\n...MONSOON TROUGH/ITCZ...\nThe monsoon trough extends from 11N15W to 06N25W. The ITCZ \nextends from 04N29W to 12N45W, where it is broken by a surface \ntrough. The ITCZ then resumes from 11N49W to 12N57W. Scattered \nmoderate convection is occurring from 08N to 17N between 35W and \n60W.\n...GULF OF AMERICA...\nSee the Special Features section above for information on the Gale\nWarning in effect for portions of the southwest basin. \nOutside fo the gales, fresh NE winds and moderate seas prevail\nacross most of the basin. \nFor the forecast, a cold front will slow down over the far\nsouthern Gulf and Yucatan Peninsula tonight and Mon, then drift \nto the southeast of the basin through Tue as it weakens. Gale- \nforce winds will persist over the SW Gulf offshore Veracruz \nthrough early Mon morning. High pressure behind the front, will \ncontinue to support fresh NE to E winds mainly over the eastern \nhalf of the Gulf through Tue. \n...CARIBBEAN SEA...\nConvection is mainly confined to the SW basin in association with\nthe eastern extension of the East Pacific monsoon trough. Moderate\nto fresh trades and 4-6 ft seas prevail in the central Caribbean.\nGentle to moderate or weaker winds and slight seas prevail \nelsewhere.\nFor the forecast, a weak pressure gradient across the region due \nto the passage of a cold front across the Bahamas and the southern\nGulf of America will maintain moderate to fresh trades in the \nsouth- central Caribbean through Thu and moderate or weaker winds \nelsewhere. The cold front will likely reach western Cuba and the \nYucatan Channel Mon night into Tue where it will remain through \nWed before dissipating. Moderate to fresh NE winds and moderate to\nrough seas will likely impact the Yucatan Channel and the NW \nCaribbean through early Wed morning. \n...ATLANTIC OCEAN...\nSee the Special Features section above for information on gales\nongoing southwest of Bermuda behind a cold front moving through\nwestern Atlantic waters. \nTo the east of this cold front, a surface trough extending along\n51W N of 22N is inducing scattered moderate convection N of 22N\nbetween 48W and 55W. Another stronger trough from 31N45W\nsoutheastward to 22N40W is producing an area of numerous strong\nconvection N of 24N between 41W and 47W. Finally, deeper in the\ntropics, a third surface trough that is drapped from 08N51W to\n15N43W is leading to a broad area of scattered moderate convection\nfrom 08N to 15N between 40W and 50W. Locally fresh or higher\nwinds, with rough seas, are present in and near convection close \nto each of these troughs, but for waters away from these features,\nwinds are generally moderate or less, with moderate seas.\nFor the forecast west of 55W, the aforementioned cold front will \nstall before dissipating into midweek. Marine conditions \nassociated with the front will affect mainly the waters W of 65W \nthrough Tue, although seas will linger through much of the week. \n", "title": "Atlantic Tropical Weather Discussion", "id": "1219921655824646146", "issued": "2026-10-18T00:15:00Z", "wmo": "AXNT20", "source": "NOAA/NWS National Hurricane Center, received via the National Weather Wire Service", "page": "https://hurricane.terrapin.com/text/1219921655824646146"}
