{"msg": "454\nAXNT20 KNHC 032222\nTWDAT \nTropical Weather Discussion\nNWS National Hurricane Center Miami FL\n0015 UTC Fri Sep 4 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 \n2200 UTC.\n...TROPICAL WAVES...\nA tropical wave is analyzed along 21W south of 20N, moving W at\n10 kt. Scattered moderate to isolated strong convection is noted \nfrom 09N to 16N, E of 22W.\nA tropical wave is along 48W, south of 20N, moving W at around 15\nkt. Convection previously associated with this wave has diminished\nthis evening. \nA tropical wave is along 63W, south of 21N, moving west at around\n15 kt. No significant convection is associated with this wave at\nthis time. \n...MONSOON TROUGH/ITCZ...\nThe monsoon trough enters the Atlantic through the coast of Mauritania\nnear 18N16W and continues southwestward to 08N29W and then to \n11N46W. The ITCZ extends from 10N50W to 08N58W. Scattered moderate\nconvection is noted from 03N to 12N between 22W and 35W.\n \n...GULF OF AMERICA...\nScattered moderate convection is focused within 30 nm on either\nside of a pair of surface trough axes, one of which is oriented\njust offshore Florida from near Apalachicola to Tampa Bay and \nanother extending southeast from just west of the mouth of the \nMississippi River to 27N89W. Winds blow toward lower pressure over\nTexas have increased to moderate to fresh offshore NE Mexico and \nwithin 90 nm of the Texas coast, and moderate to fresh NE winds \nhave developed offshore the Yucatan Peninsula, where a diurnal \nsurface trough is forming just inland. Otherwise, light to gentle \nwinds prevail outside of convection. Seas are 3 ft or less.\nFor the forecast, a diurnal trough will develop over the Yucatan \nPeninsula each afternoon supporting locally fresh easterly winds \nover the eastern Bay of Campeche through the forecast period. \nElsewhere, weak high pressure prevails and will generally allow for \nmoderate or weaker winds and slight to moderate seas through the \nnext few days. The presence of abundant tropical moisture will favor \nscattered showers and isolated thunderstorms mainly in the eastern \nGulf through the weekend. \n...CARIBBEAN SEA...\nThe pressure gradient between high pressure to the north and the\nColombian low is maintaining fresh to strong trades and 5 to 8 ft\nseas offshore Colombia and western Venezuela. Mainly moderate E\nwinds and moderate seas prevail across the remainder of the basin,\nexcept the NW Caribbean where gentle winds and slight seas are\npresent. Scattered moderate convection is noted offshore Costa\nRica and Panama, in associated with the eastern extension of the\nEastern Pacific monsoon trough. \nFor the forecast, the pressure gradient between the subtropical \nridge and lower pressure in northern South America will maintain \nfresh to pulsing strong trades along with moderate seas over the \ncentral Caribbean, and over the western portion of the eastern \nCaribbean through Sat night. These trades are forecast to increase\nto fresh to strong speeds while expanding in coverage over the \nsouth- central portion of the basin on Mon. Winds reaching near \ngale are expected Tue night near Colombia and in the Gulf of \nVenezuela. Fresh to pulsing strong east winds are expected in the \nGulf of Honduras Fri night and Tue night. Elsewhere, moderate or \nweaker winds and slight to moderate seas will continue across the \nremainder of the basin during the period.\n \n...ATLANTIC OCEAN...\nA surface trough extending offshore Florida is inducing scattered\nmoderate convection over and north of the northwest Bahamas. The\nremainder of the Atlantic forecast waters is under the influence \nof a ridge, with the main high pressure center of 1023 mb located\nNE of the Azores. Moderate to locally fresh winds and moderate \nseas prevail across much of the Atlantic S of 25N and away from \nany convection or tropical waves. Elsewhere, moderate or weaker \nwinds and 2-5 ft seas prevail. \nFor the forecast west of 55W, scattered showers and thunderstorms\nwill continue over the waters W of about 73W through the end of \nthe week as a mid-level low and surface trough gradually shift \nwestward while at the same time abundant tropical moisture remains\nin place. A cold front will then approach from the NW late this \nweekend enhancing the potential for scattered and thunderstorms \nover the NW portion of the area. Gentle to moderate east to \nsoutheast winds are over the waters west of 74W. Otherwise, the \nsubtropical ridge will provide for generally moderate or weaker \nwinds and moderate seas over the forecast waters. \n", "title": "Atlantic Tropical Weather Discussion", "id": "1207185435555758083", "issued": "2026-09-03T00:15:00Z", "wmo": "AXNT20", "source": "NOAA/NWS National Hurricane Center, received via the National Weather Wire Service", "page": "https://hurricane.terrapin.com/text/1207185435555758083"}
