084 AXNT20 KNHC 311008 TWDAT Tropical Weather Discussion NWS National Hurricane Center Miami FL 1205 UTC Sun Mar 31 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 reaches the Atlantic Ocean near 10N14W and continues southwestward to 01N18W. The ITCZ extends from 01N18W to 02S44W. Scattered moderate convection is noted within 200 nm on both sides of the ITCZ between 18W and 39W. GULF OF MEXICO... A surface high positioned east of the NW Bahamas extends a ridge to the Gulf of Mexico. No deep convection is noted across the basin. The pressure gradient between the ridge and lower pressures in Mexico result in moderate to fresh E-SE winds across much of the Gulf, except for light to gentle in the NE Gulf. A recent scatterometer satellite pass also captured pulsing fresh to strong easterly winds within 100 nm of NW Yucatan. Seas are 3-5 ft over much of the Gulf, except slight seas in the NE Gulf. For the forecast, fresh E to SE winds will prevail across the western Gulf through Mon. A cold front will enter the western Gulf on Tue. The front will extend from the Florida panhandle to the Bay of Campeche Wed, and will move SE of the area Thu. Fresh to strong winds and building seas are expected west of the front. Winds and seas will decrease Thu as the front moves out of the area. CARIBBEAN SEA... Scattered pockets of low-level moisture are found in the central Caribbean producing scattered showers. The basin is under the influence of a 1022 mb high pressure system located east of the NW Bahamas. The subtropical ridge forces strong to near gale-force easterly trade winds in the south-central Caribbean. This was confirmed by a recent scatterometer satellite pass. Seas in these waters are 7-9 ft. Fresh to strong easterly breezes and seas of 4-7 ft are noted in the north-central Caribbean, Windward Passage and lee of Cuba. Elsewhere, moderate or weaker winds and slight to moderate seas prevail. For the forecast, high pressure north of the region will continue to support pulsing of fresh to strong NE winds in the lee of eastern Cuba, across the Windward Passage, and off the southern coast of Hispaniola through Tue. Strong trade winds and rough seas will pulse off the coast of Colombia through the middle of the week. Winds and seas will then decrease by the second half of the week as the area of high press ATLANTIC OCEAN... A 1022 mb high pressure system centered east of Bahamas dominates much of the western Atlantic, maintaining fairly tranquil weather conditions. Moderate to fresh westerly winds are present north of 29N and east of 60W. Moderate to rough seas are occurring in the area described. Farther east, a cold front extends from 31N47W to NW Puerto Rico. Moderate to fresh N-NE winds and seas of 8-12 ft are occurring behind the frontal boundary. A surface trough extends from 31N43W to 11N56W. Scattered showers are evident near the trough axis. Fresh to strong southerly winds and seas of 7-9 ft north of 26N and between 39W-47W. The remainder of the tropical Atlantic is dominated by a 1022 mb high pressure system near 26N30W. Moderate to fresh westerly winds and seas of 10-13 ft are occurring north of 28N and east of 25W. Farther south, moderate easterly trade winds and seas of 8-11 ft are noted south of 20N and east of 45W. Elsewhere, moderate or weaker winds and moderate seas prevail. For the forecast W of 55W, the aforementioned front will continue to move east of the area today. Strong winds and rough seas follow the front W of 50W. Winds and seas will decrease from west to east through early Mon as high pressure continues to build in the wake of the front. The next cold front will move off the coast of Florida on Wed. This front will extend from near Bermuda to W Cuba Thu. Increasing winds and building seas will be both ahead and behind this front mainly N of 25N. $$ ERA
