{"msg": "566\nAXNT20 KNHC 102057\nTWDAT \nTropical Weather Discussion\nNWS National Hurricane Center Miami FL\n0015 UTC Wed Nov 11 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 \n2030 UTC.\n...SPECIAL FEATURES...\nMeteo-France Eastern Atlantic Gale Warning: A pair of low \npressure areas are in the eastern Atlantic with attendant fronts. \nLow pressure of 998 mb is analyzed from 33N25W with a stationary \nfront to a 10 02 mb low near 29N33W, with cold fronts also out \nahead of both of these lows. Ahead of these fronts, gale-force \nsouthwesterlies are present N of 26N to 21W. Very rough seas of up\nto 20 ft extend beyond this area of gales southward to 22W and \nwestward to 42W. These features will move rapidly E and a Gale\nWarning has been issued by Meteo-France for the Irving and Madeira\nzones, Irving through 11/06 UTC and Madeira through 11/15 UTC. \nRough to very rough seas will continue to accompany the winds.\nPlease read the latest High Seas Forecast issued by Meteo-France \nat website: https://wwmiws.wmo.int for more details.\n...MONSOON TROUGH/ITCZ...\nThe monsoon trough extends from 12N16W to 09N21W. The ITCZ \nextends from 09N21W to 08N35W to along the coast of northern South\nAmerica to 06N55W. Scattered moderate convection is from 05N to \n09N between 40W and 47W.\n...GULF OF AMERICA...\nThe combination of high pressure and and a couple of troughs, one\nin the eastern Gulf extending from 29N85W to 23N86W, and the \nother one in the western Gulf from near Corpus Christi to 23N97W \nand to 19N95W, is generally allowing for light to gentle winds \nacross the basin, with the exception of mostly moderate north \nwinds west of the western Gulf trough from 22N to 24N. Slight seas\nare over the basin, except moderate seas west of the western\ntrough. Scattered moderate convection is present across portions\nof the basin north of 24N between the troughs.\nFor the forecast, a rather strong cold front will reach the Texas\ncoast Wed night, then sweep across the Gulf through Thu night \nexiting the basin early on Fri, and followed by fresh to locally \nstrong northerly winds and building seas. Fresh to strong \nnorthwest winds are expected in the far SW Gulf Thu through Fri. \nHigh pressure will settle in over the area in the wake of the \nfront this weekend, with moderate to fresh easterly winds \nexpected. These winds increase to fresh to strong speeds over the \nNW Gulf Sun, then shifting to the north-central and NE Gulf by Sun\nnight as the gradient tightens ahead of a western Gulf frontal \nsystem and attendant low pressure that will be shifting eastward.\n...CARIBBEAN SEA...\nThe pressure gradient between high pressure centered north of\nthe region and lower pressure over South America is leading to\nfresh to strong trades over the south central basin, with moderate\nto fresh trades elsewhere, except weaker near the coast of Central\nAmerica and in the NE Caribbean. Seas are 6 to 8 ft in the south-\ncentral Caribbean and 3 to 6 ft elsewhere, except less where the\nweaker winds are. Moderate to strong convection is noted in the NW\nCaribbean from 15N to 20N from Jamaica westward, where trade \nwinds are converging near a surface trough and producing localized\nrough seas.\nFor the forecast, fresh to strong trades and locally rough seas \nwill prevail over the south-central Caribbean through Thu, with \nmainly moderate winds and seas elsewhere. The pressure gradient \nwill weaken Thu night into Fri as a cold front approaches the \nYucatan Channel, weakening the trades. Moderate to fresh northwest\nwinds and building seas are possible behind this front over the \nnorthwestern Caribbean into the weekend. \n...ATLANTIC OCEAN...\nPlease see the Special Features section for information on a Gale\nWarning for portions of the Meteo-France High Seas Forecast area.\nA stationary front extends from near 30N50W to low pressure of \n1016 mb near 27N63W then continues as mainly a stationary front to \nacross the SE Bahamas. Some moderate to fresh winds are found\nnorth of 30N between 50W and 65W where a reinforcing cold front is\nrotating through. To the east, fresh or greater winds surround the\ngale force low area described in the Special Features section\nabove across the waters north of 22N between 18W and 40W. Winds\nare moderate or weaker across the remainder of the waters, along\nwith moderate seas.\nFor the forecast west of 55W, the front and low pressure will \nexit the region Wed. Another cold front is expected to move off \nthe southeastern U.S. coast Thu night accompanied by fresh to \nstrong winds and building seas on either side of it. These \nconditions are expected to persist into the weekend. By early Sat,\nthe front will extend from near Bermuda to the southeastern \nBahamas, and stall from near 26N55W to the vicinity of the Turks \nand Caicos.\n", "title": "Atlantic Tropical Weather Discussion", "id": "1226420520287469570", "issued": "2026-11-10T00:15:00Z", "wmo": "AXNT20", "source": "NOAA/NWS National Hurricane Center, received via the National Weather Wire Service", "page": "https://hurricane.terrapin.com/text/1226420520287469570"}
