{"msg": "370\nAXNT20 KNHC 122036\nTWDAT \nTropical Weather Discussion\nNWS National Hurricane Center Miami FL\n0015 UTC Fri Nov 13 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 \n2020 UTC.\n...SPECIAL FEATURES...\nNorth-Central Atlantic Gale Warning: a strong cold front is expected\nto move off the southeastern U.S. coast tonight accompanied by \nfresh to strong winds on either side of it. The front is expected \nto reach from near 31N66W to the southeastern Bahamas by Sat \nmorning, and from near 31N55W to 25N65W and stationary to eastern \nCuba by Sun morning. Fresh to gale-force winds southwest winds \nwill precede the front to over the waters north of about 29N. The \ncold front portion will shift east of 55W late Sun night while the\nstationary portion weakens. Please, see the latest NWS High Seas \nForecast issued by the National Hurricane Center at website \nhttps://www.nhc.noaa.gov/text/MIAHSFAT2.shtml for further details.\n...MONSOON TROUGH/ITCZ...\nThe monsoon trough exits the coast of Africa near 08N13W and \nextends to 03N23W. The ITCZ extends from that point to near the\ncoast of Brazil at 11N50W. Isolated to widely moderate convection\nis located from 01N to 07N to the E of 25W.\n...GULF OF AMERICA...\nA strong cold front extends from the extreme western Florida \npanhandle to southeastern Louisiana and to Brownsville, Texas. A\npre-frontal trough is analyzed from 28N88W to Veracruz, Mexico at\n19N96W. Along with these surface features, a mid-level trough is \nsupporting isolated to scattered showers across the majority of\nthe basin. Moderate to fresh northerly winds are N of 23N and W of\nthe front, with fresh to strong NW-N winds S of 23N and W of the\nfront offshore of Veracruz. Moderate or weaker winds precede the\nfront. Seas are in the 3-6 ft range S of 25N, and W of the front\nand 3 ft or less across the remainder of the waters.\nFor the forecast, the front will sweep across the rest of the \nbasin tonight exiting the area early on Fri. A pre-frontal trough \nin the western Gulf will sustain fresh to locally strong northwest\nto north winds near Tampico and Veracruz through early on Fri. \nElsewhere, moderate to locally fresh north winds are expected in \nthe wake of the cold front. High pressure will build southward \ninto the region this weekend, with increasing easterly winds to \nfresh to strong speeds across portions of the northern and central\nGulf. Looking ahead, a second strong cold front associated to \npossible low pressure is expected to push off the Texas coast Mon \nmorning, and quickly move across the basin through Tue night. The \nresultant tight pressure gradient will lead to fresh to strong \nwinds overspreading just about the entire basin. Winds to near \ngale-force are possible in the northern portion of the NE Gulf \nearly next week.\n...CARIBBEAN SEA...\nThe pressure gradient between the Bermuda High north of the region\nand a 1007 mb low pressure along the NW coast of Colombia is \ncausing fresh to strong trades over the central Caribbean from 11N\nto 17N with seas 6-9 ft. Moderate to fresh trades are found\nelsewhere from 11N to 21N E of 76W, with moderate or weaker winds\nacross the remainder of the basin. A pair of surface troughs are\nanalyzed in the western Caribbean supporting scattered showers and\nthunderstorms mainly over the NW Caribbean waters.\nFor the forecast, fresh to strong trades will prevail over the \ncentral and eastern Caribbean tonight, with gentle to moderate \nwinds elsewhere. The pressure gradient will slacken starting Fri \nas a cold front approaches the Yucatan Channel leading to a \nweakening of the trades. Moderate to fresh northeast to east winds\nare likely behind this front over the northwestern Caribbean Sat \nthrough Sun. Looking ahead, fresh to strong trades may become \nreestablished over the south central Caribbean early next week. \n...ATLANTIC OCEAN...\nA strong cold front is inland, moving across the SE United States.\nA pre-frontal trough is analyzed over the waters from 31N74W to NE\nof the Bahamas. Scattered moderate convection is found across the\nwaters N of 20N and W of 60W. Moderate to fresh winds and 3-6 ft\nseas cover this same area, locally strong winds N of 30N. To the\nE, a weakening cold front is found from 31N30W to 28N52W\nsupporting some isolated to widely scattered moderate convection\nfrom 20N to 31N between 50W and 60W, and from 26N to 31N between\n40W and 50W. Yet another cold front is to the E, reaching from the\ncoast of Morrocco at 24N16W to 20N40W. Moderate to fresh winds are\nfound N of the front to 29N between Morrocco and 20W. Rough seas\nare also found behind this front, mainly across the waters E of\n25W. Moderate seas are across the remainder of the waters. Broad \nhigh pressure blankets the remainder of the waters. A belt of \nmoderate to fresh trades is found over the southern waters from \n06N to 16N to the W of 30W, with moderate or weaker winds across \nthe remainder of the waters.\nFor the forecast west of 55W, a strong cold front is expected to \nmove off the southeastern U.S. coast tonight accompanied by fresh \nto strong winds on either side of it. The front is expected to \nreach from near 31N66W to the southeastern Bahamas by Sat morning,\nand from near 31N55W to 25N65W and stationary to eastern Cuba by \nSun morning. Fresh to gale-force winds southwest winds will \nprecede the front to over the waters north of about 29N. The cold \nfront portion will shift east of 55W late Sun night while the \nstationary portion weakens. On Sun, winds will briefly diminish \nbelow fresh speeds over the forecast waters. Looking ahead, a \nbuilding Bermuda High should increase northeast winds up to fresh \nto strong speeds south of 27N west of 65W Mon and Mon night, and \nexpand northward in coverage Tue and Tue night.\n", "title": "Atlantic Tropical Weather Discussion", "id": "1226982701748060162", "issued": "2026-11-12T00:15:00Z", "wmo": "AXNT20", "source": "NOAA/NWS National Hurricane Center, received via the National Weather Wire Service", "page": "https://hurricane.terrapin.com/text/1226982701748060162"}
