{"msg": "975\nAXNT20 KNHC 220325\nTWDAT \nTropical Weather Discussion\nNWS National Hurricane Center Miami FL\n0615 UTC Sat Aug 22 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 0000 UTC surface analysis and satellite imagery through \n0300 UTC.\n...TROPICAL WAVES...\nA tropical wave is along 23W, moving westward at 10 to 15 kt.  \nScattered moderate to isolated strong convection is noted S of 24N \nbetween 22W and 27W.\nA second tropical wave is along n eastern Atlantic tropical wave\nhas its axis along 45W south of 20N, moving westward at 15 to 20 \nkt. No significant convection is noted near the wave axis.\nA third tropical wave has its axis along 56W south of 20N moving \nwestward at 15 to 20 kt. No significant convection is noted near\nthe wave axis.\nA tropical wave is over the central Caribbean along 79W south of \n20N, moving westward at about 15 kt. Convection is limited near \nthe wave axis.\n...MONSOON TROUGH/ITCZ...\nThe monsoon trough enters the Atlantic through the coast of Mauritania\nnear 18N16W and continues southwestward to 11N54W. The ITCZ \nextends from 10N46W to 11N54W. Outside of convection associated \nwith the tropical waves, scattered moderate convection is within\n200 nm on either side of the monsoon trough between 34W and 40W.\n...GULF OF AMERICA...\nHigh pressure continues to dominate the Gulf region with a 1017 mb\ncenter near 24N89W. This pattern is supporting mainly light to \ngentle winds and slight to moderate seas. The highest seas of 3 \nft are noted over the Bay of Campeche based on altimeter data. \nConvection has flared-up over parts of Florida, the north-central\nGulf, and along the coast of Mexico roughly between Tuxpan and \nVeracruz. A diffluent pattern aloft is helping to induce this \nconvective activity. \nFor the forecast, weak high pressure centered over the\ncentral Gulf will prevail into the middle of next week,\nsupporting gentle to moderate winds and slight to locally\nmoderate seas. A surface trough will generate fresh to strong \nwinds north and west of the Yucatan Peninsula in the early \nevenings. These winds will spread westward away from the peninsula\nat night as the trough migrates into the SW Gulf. \n...CARIBBEAN SEA...\nA tropical wave is moving across the western half of the basin. \nRefer to the section above for details.\nThe pressure gradient between weak high pressure centered S of \nBermuda and low pressure over northern Colombia is supporting \nfresh to strong trades over the most of the central Caribbean, \nwith moderate to fresh trades elsewhere, with the exception of \ngentle winds over the NW part of the basin. Seas are moderate, \nexcept 7 to 9 ft in the south-central Caribbean and slight seas \nover the northwest Caribbean. Shallow moisture embedded in the \ntrade winds flow is moving across the region producing isolated to\nscattered passing showers. \nFor the forecast, the pressure gradient will continue to sustain \nfresh to strong trade winds and rough seas across the south- \ncentral Caribbean through much of the forecast period. Moderate to\nfresh winds and moderate seas will prevail over most of the rest \nof the basin, aside from the northwest basin where lesser winds \nwill dominate. A tropical wave currently over the tropical \nAtlantic is expected to move across the eastern Caribbean Tue \nthrough early Wed, and across the eastern part of the central \nCaribbean during the rest of Wed. Another tropical wave may \napproach the Lesser Antilles and far eastern Caribbean late on \nWed. These waves will enhance the trade wind flow across those \nwaters. \n...ATLANTIC OCEAN...\nThree tropical wave are moving westward between W Africa and the\nLesser Antilles. See the Tropical Waves section above for \ndetails.\nA trough is analyzed over Florida, reaching the W Atlantic from\n29N78W to 27N80W. To the E, a 1021 mb high is centered near\n26N72W. A weak 1018 mb low is centered east-southeast of Bermuda \nnear 30N56W. A surface trough extends from the low center to \n24N64W. Scattered showers and thunderstorms are active near these \nfeatures. A surface through is analyzed from 28N39W to 22N43W with\nscattered showers. Elsewhere west of 55W, the subtropical ridge \ndominates, anchored by 1021 mb high pressure between Bermuda and \nthe central Bahamas near 25N67W. Fresh E to SE winds are funneling\nalong the north coast of Hispaniola south of the ridge, \nsupporting 3 to 5 ft seas. The remainder of the Atlantic forecast \nregion is under the influence of a ridge with a 1028 mb high \npressure located SW of the Azores near 35N37W. This system \nsupports moderate to fresh NE to E winds and seas of 5 to 7 ft, \nexcept fresh to locally strong NE winds and rough seas off the \ncoasts of Mauritania and Senegal.\nFor the forecast west of 55W, the weak pressure gradient will \nsupport mostly light to gentle winds over most of the waters north\nof 23N into early next week. Moderate to fresh trades are \nexpected south of about 23N, highest off northern Hispaniola, \nthrough the period. These trades may pulse to fresh to strong \nspeeds off northern Hispaniola at night through most of the \nforecast period. Meanwhile, the northern portion of a tropical \nwave is expected to move across the waters S of about 23N and E of\nthe Bahamas next week freshening the trade winds. Yet, the \nnorthern portion of another tropical wave may move across the SE \nportion of the area Wed and Wed night increasing the trades over \nthose waters. \n", "title": "Atlantic Tropical Weather Discussion", "id": "1203564578857025538", "issued": "2026-08-22T06:15:00Z", "wmo": "AXNT20", "source": "NOAA/NWS National Hurricane Center, received via the National Weather Wire Service", "page": "https://hurricane.terrapin.com/text/1203564578857025538"}
