412 AXNT20 KNHC 032329 TWDAT Tropical Weather Discussion NWS National Hurricane Center Miami FL 0015 UTC Wed Jun 4 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. ...TROPICAL WAVES... The axis of an eastern Atlantic tropical wave is analyzed near 24W, from 14N southward to 03N, moving westward at 5 to 10 kt. Scattered showers and thunderstorms are noted near the south end of the wave axis. ...MONSOON TROUGH/ITCZ... The monsoon trough enters the Atlantic through the coast of Africa near 09N13W and extends southwestward to near 06N16W. The ITCZ continues from 06N16W to 04N21W, where it is broken by a tropical wave. The ITCZ then resumes at 04N27W, and extends to 05N40W to 03N51W. No significant convection is occurring near these features. ...GULF OF AMERICA... A surface trough extends over the east-central Gulf. This trough along with an upper level low supports numerous moderate and isolated strong convection in the far E Gulf generally to the E of 86W, including the Florida Straits. A second surface trough extends through the central Bay of Campeche. Moderate to locally fresh E to SE winds prevail over the northeastern and eastern Gulf, with gentle to moderate winds over the remainder of the basin. Seas of 1-3 ft prevail across the Gulf. For the forecast, moderate to fresh E to NE winds are expected each afternoon and evening north of the Yucatan Peninsula and into the eastern Bay of Campeche as a trough develops daily and moves westward. Expect moderate to fresh SE winds and building seas across the western and south-central Gulf through Fri between a trough over northern Mexico and high pressure over the Carolinas. ...CARIBBEAN SEA... An upper level low is aiding in the development of scattered moderate convection across portions of the NW Caribbean W of 81W and N of 15N. A ridge of high pressure is N of the Caribbean waters. The pressure gradient between this area of high pressure and the Colombian low is supporting fresh to strong E winds over much of the central Caribbean. Moderate to fresh E to SE winds prevail elsewhere. Seas are in the 8-12 ft range over the central Caribbean, and 4-7 ft elsewhere. For the forecast, fresh to strong E winds and moderate to rough seas will continue across most of the Caribbean into late week, then diminish slightly at the end of the week. ...ATLANTIC OCEAN... A surface trough extends over the NW waters off northern Florida, and a cold front extends just north of the Florida border along 31N. These features as well as an upper level low support numerous moderate convection across the waters S of 30N and W of 72W. High pressure dominates the remainder of the tropical and subtropical waters. Moderate to fresh trades and seas of 4-7 ft prevail across areas S of 20N and W of 35W, as well as N of 20N between the W coast of Africa and 50W. NE winds are locally strong in between the Canary Islands and off the coast of Morocco. Moderate or weaker winds and seas of 3-5 ft prevail elsewhere across the Atlantic. For the forecast west of 55W, a cold front will move SE of Bermuda tonight, then drift E across the NE waters through late this week. A surface trough along the SE U.S. coast will bring showers and thunderstorms offshore Florida over the next couple of days. Otherwise, high pressure will dominate. A tight pressure gradient will lead to fresh to strong winds pulsing nightly offshore Hispaniola through Fri. $$ ADAMS
