{"msg": "674\nAXNT20 KNHC 050940\nTWDAT \nTropical Weather Discussion\nNWS National Hurricane Center Miami FL\n1215 UTC Thu Nov 5 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 0600 UTC surface analysis and satellite imagery through \n0930 UTC.\n...SPECIAL FEATURES...\nWestern Atlantic Gale Warning: Latest scatterometer satellite \npass confirmed winds to gale force south of Bermuda, between 1023 \nmb high pressure centered north of Bermuda near 38N63W, and 1007 \nmb low pressure near 27N65W. Strong to near-gale force winds are \nnoted from 27N to 31N between 55W and 70W, with associated seas \nranging from 8 ft to 13 ft. Scattered showers and isolated \nthunderstorms are also active in this area. Environmental \nconditions could support this system gradually acquiring \nsubtropical characteristics through this weekend while it moves \nslowly eastward over the western and central subtropical Atlantic.\nBy early next week, environmental conditions are forecast to \nbecome unfavorable for further development. Chances of this \ndevelopment remain low through 48 hours, and medium through the \nnext seven days. Regardless of such development, the area of winds\nand seas will expand as the low shifts eastward, with gale force \nwind and very rough seas will expand eastward north of 25N \nreaching as far east as 45W by early Mon. Winds and seas start to \ndiminish thereafter, as environmental conditions are forecast to \nbecome unfavorable for further development. \nPlease read the latest High Seas \nForecast issued by the National Hurricane Center at website: \nhttps://nhc.noaa.gov/text/HSFAT2.html\nHeavy Precipitation across Central America: Deep-layer troughing \nover the northwestern Caribbean extends southwestward across\nnorthern portions of Central America and into the tropical\neastern Pacific. This feature will interact with enhanced low- \nlevel moisture and onshore flow south of the monsoon trough over\nthe next several days. This will favor heavy precipitation \ndeveloping across Central America starting today and lasting \nthrough at least Friday. The heaviest precipitation is expected \nacross Nicaragua and Costa Rica, with the bulk of precipitation \noccurring through today. Heavy rainfall may lead to life- \nthreatening flash flooding and landslides. \nPlease refer to your local weather agency and the International \nDesk at the Weather Prediction Center for more details.\n...MONSOON TROUGH/ITCZ...\nThe monsoon trough reaches the Atlantic from 11N16W to 08N20W. \nThe ITCZ extends from 08N20W to 08N59W. Scattered moderate \nconvection is noted from 03N to 11N and E of 47W.\n...GULF OF AMERICA...\nA stationary front reaches from Gulfport, MS to Tampico, Mexico.\n1014 mb high pressure is over the eastern and central Gulf, \ncentered near 26N86W. This pattern is supporting light breezes \nand 1-3 ft seas across the basin.\nFor the forecast, the frontal boundary will weaken and dissipate \ntoday. Moderate northwest to north winds prevail west of the \nfront. The next cold front is expected to move across the Gulf \nwaters this weekend. Near gale NW winds are expected in the SW \nGulf Sun night and Mon west of the front. Fresh to strong north \nwinds will develop elsewhere west of the front on Sun through \nearly next week as it moves east across the basin.\n...CARIBBEAN SEA...\nA cluster of thunderstorms is active southeast of Jamaica. \nScattered thunderstorms are also active across the southern \napproaches to the Windward Passage. Broad 1009 mb low pressure \nnear Grand Cayman Island is along a surface trough at 82W from 17N\nand 20N. This pattern is supporting light breezes and 1-3 ft seas\nacross the basin. \nFor the forecast, a weak pressure gradient prevails across \nthe basin supporting moderate trade winds, along with moderate \nseas. The pressure gradient will further loosen across the area \ntonight. This will diminish the moderate trades across the central\nand eastern Caribbean through the forecast period. \n...ATLANTIC OCEAN...\nPlease see the Special Features section for information on a Gale\nWarning in the western Atlantic. \nElsewhere, a cold front enters the central Atlantic near 31N28W \nto 26N38W, then continues as stationary to 27N49W. Farther south,\na trough reaches from 19N27W to 13N31W. This pattern is \nsupporting gentle to moderate breezes and 4-6 ft combined seas in \nN swell.\nFor the forecast west of 55W, the low pressure will drift through\nFri, then slowly move east-northeastward during the weekend. An \narea of strong to gale-force winds, and rough to very rough seas, \npeaking near 14 ft, has developed north of the low pres and will \nexpand eastward through Sun, impacting the waters mainly north of \nabout 27N. The gale- force winds will likely be north of 29N \nthrough the end of the week. Elsewhere, a weakening cold front \nwill move across the waters between Florida and 75W Fri and Fri \nnight, then dissipate Sat and Sat night. \n", "title": "Atlantic Tropical Weather Discussion", "id": "1224871933257547779", "issued": "2026-11-05T12:15:00Z", "wmo": "AXNT20", "source": "NOAA/NWS National Hurricane Center, received via the National Weather Wire Service", "page": "https://hurricane.terrapin.com/text/1224871933257547779"}
