016 AXNT20 KNHC 192219 TWDAT Tropical Weather Discussion NWS National Hurricane Center Miami FL 0015 UTC Wed May 20 2026 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 2130 UTC. ...TROPICAL WAVES... An Atlantic tropical wave is analyzed along 60W, approaching the Windward Islands S of 16N, and is moving W near 10 kt. Scattered moderate convection is noted mainly behind the wave, S of 09N between 50W and 58W. ...MONSOON TROUGH/ITCZ... The monsoon trough enters the Atlantic through the coast of Guinea near 10N14W, then runs southwestward to 05.5N20W. The ITCZ extends from 05.5N20W to the coast of Brazil near 02N51W. Scattered moderate convection is seen from 00N to 06N between 10W and 50W. ...GULF OF AMERICA... The subtropical ridge over the western Atlantic extends westward into the northern Gulf states, to eastern Texas. The resultant pressure gradient across the basin is forcing moderate to fresh E to E-SE winds and moderate seas across all but the Florida coastal waters, but also includes the Florida Straits. Peak seas are to 7 ft across the offshore waters of south Texas and NE Mexico. Generally fair weather conditions dominate the basin, although some weakening thunderstorms are have shifted westward off of southwest and central Florida and into the local coastal waters. For the forecast, a surface ridge will remain over the SE United States for the next several days, forcing E to SE winds across the Gulf. Expect moderate to fresh winds over the W Gulf, pulsing to strong each evening through Wed night offshore of the Yucatan Peninsula. Beginning on Thu, the pressure gradient will relax and tranquil marine conditions should prevail through the weekend. ...CARIBBEAN SEA... Scattered moderate convection is occurring in the far SW Caribbean, as the eastern extension of the East Pacific monsoon trough reaches across the basin along 10N. Scattered showers and thunderstorms are also ongoing across the Windward Passage as well as the southern coasts and adjacent waters of Cuba. The pressure gradient between a 1030 mb high near Bermuda and the Colombia Low supports fresh to strong trades across the central to SW Caribbean, where seas are 8-12 ft, as indicated by recent satellite altimeter data. Moderate to fresh trades and moderate seas prevail in the eastern Caribbean and the Gulf of Honduras. The remainder of the NW Caribbean is seeing gentle to moderate trades and 3-5 ft seas. For the forecast, the pressure gradient between the Bermuda High north of the area and the Colombian Low will support fresh to strong trades over the S central Caribbean for the next several days. Fresh to strong trades will also occur over the Gulf of Honduras today and tonight before weakening tomorrow. Large E to SE swell will impact the tropical N Atlantic waters tonight before subsiding tomorrow. Looking ahead, fresh to strong trades over the Gulf of Honduras are likely to return again starting on Sat night. ...ATLANTIC OCEAN... Scattered moderate convection NE of the Bahamas to 69W and across the southern Bahamas are associated with a weak surface trough and upper level low centered near 28.5N74W. To the east, a cold front enters the discussion waters near 31N39W and extends to 29N63W. Recent satellite scatterometer data indicates moderate N to NE winds north the front, and moderate to fresh SW winds south of the front to 29N. Otherwise, the subtropical ridge dominates, resulting in fresh to locally strong trades and moderate seas prevailing across much of the Atlantic S of 23N, where seas are 7 to 10 ft, as verified by recent satellite altimeter data. Areas N of 23N and away from any aforementioned features are seeing gentle to moderate trades and seas of 4-7 ft prevail. Moderate to fresh NE trades and moderate seas prevail across most of the area between 20W and 35W. For the forecast west of 55W, an upper-level low will continue to produce scattered showers and thunderstorms along a surface trough to the east of the Bahamas through Thu. SE winds will pulse fresh to strong north of Hispaniola during the afternoon and evening hours for the next several days. Elsewhere, surface ridging north of our waters should cause winds and seas to remain quiescent through the weekend. $$ Stripling
