####018003797#### AXNT20 KNHC 011009 TWDAT Tropical Weather Discussion NWS National Hurricane Center Miami FL 1205 UTC Wed May 1 2024 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 0600 UTC surface analysis and satellite imagery through 1000 UTC. ...MONSOON TROUGH/ITCZ... The monsoon trough enters the Atlantic through the coast of Senegal near 13N16W and continues southwestward to 04N23W. The ITCZ extends from 04N23W to 04N50W. Scattered moderate convection is active S of 06N and E of 32W. ...GULF OF MEXICO... High pressure over the western Atlantic is supporting gentle to moderate SE winds across the Gulf, except west of the Yucatan Peninsula where locally fresh NE winds are noted. 3 to 5 ft combined seas are noted across the basin. Light to moderate smoke from agricultural fires over southern Mexico is creating hazy conditions for much of the southwest Gulf. For the forecast, the pressure gradient between the ridge and lower pressures in Texas and Mexico will support fresh to strong pulsing winds in the western half of the Gulf Wed night into the weekend. Moderate or weaker winds will prevail in the eastern half of the basin. Winds will pulse to strong speeds nightly near and to the NW of the Yucatan Peninsula due to local effects induced by a thermal trough. ...CARIBBEAN SEA... A 1019 mb high pressure north of the area supports moderate to fresh easterly trade winds over much of the Caribbean basin. Fresh to strong winds are pulsing in the offshore waters of southern Hispaniola, as verified by latest scatterometer data. Scatterometer data also noted mainly gentle winds over the NW Caribbean. Seas are mainly 4 to 6 ft across the eastern and central basin, with 3 to 5 ft seas in the NW basin. For the forecast, the ridge is expected to slide eastward and weaken some over the next few days, resulting in mainly gentle to moderate trade winds through the week and into the weekend. Northerly swell will support rough seas through the the NE Caribbean passages until this afternoon. ...ATLANTIC OCEAN... 1019 mb high pressure is centered between Bermuda and northeast Florida near 30N68W. To the east, a cold front extends from 31N49W to 28N64W. Another cold front extends from 32N36W to 26N40W. Scattered showers are noted along the fronts. A recent scatterometer satellite pass indicated that fresh winds prevail off the north coast of Puerto Rico to Hispaniola and across the Old Bahama Channel north of eastern Cuba. Buoy observations and latest altimeter satellite data show combined seas of 8-10 ft are affecting the waters N of 28N and E of 60W. A scatterometer pass showed fresh to strong SW winds north of 29N between 45W and 50W, ahead of the weak cold front east of Bermuda. Moderate winds and seas are noted elsewhere west of 35W. Farther east, high pressure west of the Azores is supporting a large area of fresh to strong NE winds and 8 to 9 ft over the eastern Atlantic. For the forecast west of 55W, moderate to fresh easterly winds will continue over the waters S of 22N and W of 60W through today, including in the approaches of the Windward Passage. The high pressure will move eastward while slowly weakening. A surface trough may develop just N of Hispaniola over the next 48 hours and move east toward the waters just north of Puerto Rico by the end of the work week. $$ ERA
