000 AXNT20 KNHC 040536 TWDAT Tropical Weather Discussion NWS National Hurricane Center Miami FL 0605 UTC Mon Apr 4 2022 Tropical Weather Discussion for North America, Central America Gulf of Mexico, 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 0000 UTC surface analysis and satellite imagery through 0520 UTC. ...MONSOON TROUGH/ITCZ... The monsoon trough passes through the coastal plains of Sierra Leone near 08N13W, to 04N15W and 02N17W. The ITCZ continues from 02N17W, to the Equator along 22W, to 01S30W, 02S34W, and to 01S43W. Precipitation: scattered to numerous strong is from 03N to 05N between 13W and 17W. Widely scattered moderate to isolated strong is from 06N from 20W westward. Isolated moderate to locally strong is in the remainder of the area from 10N southward from 60W eastward. ...GULF OF MEXICO... A cold front passes through 31N71W in the Atlantic Ocean, to the Florida coast near 26N80W, to 24N87W in the Gulf of Mexico. Precipitation: widely scattered moderate to isolated strong covers the water areas and the land areas from Atlantic Ocean coast of Cuba to 28N between 77W in the Atlantic Ocean and 85W in the Gulf of Mexico. Scattered to broken multilayered clouds, and possible rainshowers, are in the Gulf of Mexico from 22N to 29N. Moderate easterly winds, and wave heights that range from 3 feet to 4 feet, are to the north of the cold front. Gentle to moderate southerly winds, and wave heights that range from 2 feet to 3 feet, are to the south of the cold front. A weak cold front from near Naples, Florida to 24N88W will drift SE and dissipate overnight. Southerly flow will return through the basin after the boundary dissipates. The next cold front is forecast to move off the Texas coast midweek. ...CARIBBEAN SEA... The GFS model for 700 mb shows a NW-to-SE oriented trough in the coastal waters from SE Nicaragua, to Costa Rica, Panama, and Colombia. Precipitation: scattered moderate to widely scattered strong is within 125 nm of the coasts of Panama and Costa Rica between 79W and 84W. ENE to ESE trade winds continue in the basin. Gentle to moderate winds, and wave heights that range from 3 feet to 4 feet, are in the NW part of the basin. Fresh to strong trade winds, and wave heights that range from 6 feet to 8 feet, are in the south central part of the area to the north of Colombia. Gentle to moderate trade winds, and wave heights that range from 4 feet to 6 feet, cover the rest of the Caribbean Sea. High pressure north of the area will support fresh to strong winds in the south central Caribbean Sea near the coast of Colombia tonight. Fresh to strong winds will develop in the Gulf of Honduras late Mon and continue into Thu. Moderate to fresh winds will prevail elsewhere. A cold front may approach the Yucatan Channel Fri. ...ATLANTIC OCEAN... A cold front passes through 31N71W, to the Florida coast near 26N80W, to 24N87W in the Gulf of Mexico. Precipitation: widely scattered moderate to isolated strong covers the water areas and the land areas from Atlantic Ocean coast of Cuba to 28N between 77W in the Atlantic Ocean and 85W in the Gulf of Mexico. Scattered to broken multilayered clouds, and possible rainshowers, are in the Gulf of Mexico from 22N to 29N. Fresh to strong winds, and wave heights that range from 4 feet to 6 feet, are noted in the SW N Atlantic Ocean. It is possible that some wave heights may be reaching 8 feet near the comparatively fastest wind speeds. Light winds, and wave heights that range from 4 feet to 6 feet, are in the areas of the surface anticyclonic wind flow. Moderate to fresh winds, and wave heights that range from 6 feet to 8 feet, are S of 23N in the Tropical Atlantic Ocean. One eastern Atlantic Ocean surface trough starts at 30N12W, and it continues to 22N20W 19N30W and 19N42W. A second surface trough extends from a 1002 mb 30N14W low pressure center, to 25N20W and 23N30W. Precipitation: rainshowers are possible from 16N northward from 60W eastward. Clusters of clouds with possible rainshowers are from 16N to 21N between 40W and 62W. These clouds are associated with a remnant cloud line from a frontal boundary that dissipated during the last few days. Strong NW winds, and wave heights that range from 12 feet to 15 feet, are to the north of the surface troughs. Fresh to locally strong SW winds, and wave heights that range from 7 feet to 9 feet, are to the east of the Canary Islands, and N of 23N between the Sahara/Morrocco coast and 20W. A 1022 mb high pressure center is near 29N42W. Broad surface anticyclonic wind flow covers the Atlantic Ocean between the 31N71W cold front and the two eastern Atlantic Ocean surface troughs. A cold front from 31N72W to near West Palm Beach, Florida will move E and gradually dissipate into Tue night. The next cold front will move off the SE U.S. coast Thu night. $$ MT/SK
