995 AXNT20 KNHC 222315 TWDAT Tropical Weather Discussion NWS National Hurricane Center Miami FL 0015 UTC Sun Mar 23 2025 Tropical Weather Discussion for North America, Central America Gulf of America, Caribbean Sea, northern sections of South America, and Atlantic Ocean to the African coast from the Equator to 31N. The following information is based on satellite imagery, weather observations, radar and meteorological analysis. Based on 1800 UTC surface analysis and satellite imagery through 2300 UTC. ...SPECIAL FEATURES... Caribbean Gale Warning: High pressure N of area combined with the Colombian low will support pulsing winds to gale force offshore of Colombia each night and early morning through early next week. Seas will build to 14 or 15 ft with the strongest winds. Please refer to the latest NWS High Seas Forecast issued by the National Hurricane Center at the website: https://www.nhc.noaa.gov/text/MIAHSFAT2.shtml, for more details. ...MONSOON TROUGH/ITCZ... The monsoon trough enters the Atlantic through the coast of Guinea Bissau near 12N16W and continues southward to 03N20W. The ITCZ extends from 03N20W to 00N50W. Scattered moderate and isolated strong convection is occurring from the equator to 06N between 10W and 17W. Scattered moderate convection is also noted from the equator to 04N between 20W and 35W. ...GULF OF AMERICA... High pressure of 1024 mb located over the NE Gulf dominates the basin supporting a gentle to moderate anticyclonic flow, except W of about 95W where scatterometer data indicate moderate to fresh SE winds. Seas are in general 2 to 4 ft, except 1 to 2 ft over the NE Gulf. There winds are light and variable due to the presence of the high pressure center. Strong SW winds aloft are supporting abundant cloudiness with possible showers mainly over the western Gulf. For the forecast, high pressure will prevail over the Gulf, supporting moderate to locally fresh S to SE winds over the western and central Gulf, and gentle to moderate winds in the eastern basin into early next week. A surface trough will develop over the Yucatan Peninsula and move into the Bay of Campeche nightly through Sun, supporting pulses of fresh to strong winds over adjacent waters. The next cold front may enter the northern Gulf late Mon, but will likely dissipate as it moves into the central and eastern Gulf waters through Tue night. Looking ahead, high pressure building over the northeastern Gulf in the wake of the front will support moderate to fresh SE winds and building seas across the northwest Gulf by Thu. ...CARIBBEAN SEA... A Gale Warning remains in effect offshore Colombia. Please, refer to the Special Features section above for more information. A moderate pressure gradient between a surface ridge north of Greater Antilles and a 1006 mb Colombian Low is forcing fresh to strong NE to E trades over the central Caribbean. Seas over these waters are 7 to 10 ft. Elsewhere, the trades are gentle to moderate with seas of 4 to 6 ft, except 2 to 4 ft over the NW Caribbean. A surface trough extends from the central Atlantic to Puerto Rico and the US/UK Virgin Islands. Scattered showers are occurring over the Virgin Islands, Puerto Rico, and between Jamaica and Honduras/Nicaragua. For the forecast, fresh to strong NE to E winds offshore of Colombia and Venezuela will pulse to gale force offshore of Colombia each night and early morning through early next week. Fresh to occasionally strong NE winds will also pulse in the Windward Passage into early next week. Fresh to strong SE winds will extend across the Gulf of Honduras from Sun night through the middle of the week. ...ATLANTIC OCEAN... A cold front extends from 31N53W to 26N64W, then becomes stationary to central Cuba. Scattered showers are along the frontal boundary. Winds are moderate on either side of the front while seas of 8 to 10 ft in NW swell are noted N of 26N between the front and 72W. As previously mentioned, a surface trough extends over the central Atlantic from 27N49W to Puerto Rico and the US/UK Virgin Islands. Scattered showers are occurring within about 60 NM of the trough axis. A 1033 mb high pressure situated over the Azores is helping to promote generally fresh to strong NE winds N of 12N and E of 30W, including the Cabo Verde Islands. Seas are 8 to 10 ft within these winds based on altimeter data. Moderate to fresh trades and moderate to rough seas are evident across the remainder of the tropical Atlantic. Elsewhere, winds are moderate or weaker across the Atlantic with moderate seas. For the forecast west of 55W, the stationary portion of the front will dissipate while the cold front shifts east of 55W overnight. High pressure will build in the wake of the front over the western Atlantic along 30N. This pattern will support gentle breezes and slight to moderate seas north of 22N into early next week. The area of high pressure will shift eastward Mon enabling a weak cold front to move off the northeast Florida coast Mon night. Fresh to strong winds may pulse off the northern coast of Hispaniola late Sun through mid week. Looking ahead, another front may move into waters between northeast Florida and Bermuda Wed. $$ GR
