####018005144#### AXNT20 KNHC 030432 TWDAT Tropical Weather Discussion NWS National Hurricane Center Miami FL 0615 UTC Sat May 3 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 0000 UTC surface analysis and satellite imagery through 0429 UTC. ...MONSOON TROUGH/ITCZ... The monsoon trough axis enters the Atlantic along the coast of Guinea-Bissau near 11N16W and extends southwestward to 06N19W. The ITCZ extends from 06N19W to near 02N48W. ...GULF OF AMERICA... A high pressure ridge extends from the western Atlantic through the lower Mississippi Valley. A weak diurnal trough is evident over the Yucatan Peninsula. This pattern is supporting gentle to moderate SE breezes the eastern Gulf, and mainly moderate SE winds over the western Gulf, although fresh to strong E winds are pulsing off the northern coast of the Yucatan Peninsula. Wave heights are 2 to 4 ft in the northeast Gulf, and 4 to 6 ft elsewhere. Scattered showers and thunderstorms are active off the coast of TX and LA. For the forecast, a ridge will continue to dominate the Gulf waters through Sat morning supporting moderate to fresh east to southeast winds over most of the basin, with the exception of gentle to moderate winds in the NE Gulf. East winds will pulse to fresh to strong speeds north of the Yucatan peninsula and over the Bay of Campeche at night through early next week in association with a diurnal trough, while mainly moderate to locally fresh E to SE winds and moderate seas are expected across the Straits of Florida through Tue. A weak cold front will reach the northern Gulf waters early Sat, and remain there on Sun before shifting east of the basin on Mon. High pressure will then build southward across the Gulf leading to mostly moderate to fresh easterly winds over most of the forecast zones early next week, increasing to fresh to strong over the western Gulf by early Tue as the pressure gradient tightens. Another weak front may reach the NW Gulf by early Thu. ...CARIBBEAN SEA... A weak pressure gradient between the Bermuda High and a 1010 mb Colombian Low is only forcing generally gentle to moderate trades and 2 to 4 ft seas across most of the Caribbean. The exceptions are fresh NE winds and 4 to 5 ft seas over the Windward Passage off Colombia, and offshore of northern Honduras. Aside from the convection in the southwest Caribbean associated with the Pacific monsoon trough, no other significant deep convection is depicted at this time. For the forecast, high pressure over the western Atlantic combined with the Colombian low will support fresh northeast winds through the Windward Passage, in the lee of central Cuba, and south of the Dominican Republic, mainly near Cabo Beata, tonight. Moderate to fresh E to SE winds will pulse north of Honduras, increasing to fresh to strong Tue night and Wed night. Unsettled weather is expected to continue over most of the eastern Caribbean into the weekend. Otherwise, gentle to moderate trades and slight to moderate seas are expected over the basin into early next week. ...ATLANTIC OCEAN... A surface trough extends from a 1018 mb low pressure near 29.5N52W to a 1014 mb low pressure near 25N51W to 14N59W. Scattered moderate convection is depicted east of these features from 21N to 28N between 38W and 50.5W. A 1025 mb high pressure is centered northeast of Bermuda near 39N59W. This pattern is supporting moderate to fresh NE to E winds and 5 to 7 ft seas from 18N to 29N and west of 52W. Fresh to strong SE winds and seas to 8 ft are ongoing within 300 nm in the east and southeast semicircles of the 1014 mb low. Elsewhere, mostly moderate NE to E winds prevail across the eastern Atlantic, with 5 to 9 ft seas in N swell. For the forecast west of 55W, a surface trough extends from a 1018 mb low pressure near 29.5N52W to a 1014 mb low pressure near 25N51W to 14N59W. These features will generally persist over the central Atlantic between 50W and 60W through Sat. Fresh to strong NE to E winds and moderate to rough seas are expected over the NW part of it tonight and Sat due to the pressure gradient between the trough/low and high pressure to the N. Meanwhile a cold front from 31N60W to 30N65W to 31N69W will merge with these features Sat. The lows should dissipate by Sun, while the trough is forecast to drift westward over the forecast waters through at least early next week. An area of fresh to strong easterly winds and rough seas will persist near the northern end of the trough axis affecting mainly the NE waters. Looking ahead, a weak cold front may approach then stall near the southeastern U.S. coast Sun and Mon. $$ KRV
