112 AXNT20 KNHC 032204 TWDAT Tropical Weather Discussion NWS National Hurricane Center Miami FL 0015 UTC Thu Dec 4 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 1800 UTC surface analysis and satellite imagery through 2100 UTC. ...SPECIAL FEATURES... Agadir Gale Warning: The pressure gradient between a 1031 mb high centered near 35N27W and lower pressures over the Mediterranean Sea will support NE winds gusting to gale force offshore the Moroccan coast near Agadir. Accordingly, Meteo-France has issued a Gale Warning for the Agadir zone from 03/15 UTC to 04/00 UTC. For more information, please visit Meteo-France`s website at: https://wwmiws.wmo.int/index.php/metareas/display/2. ...MONSOON TROUGH/ITCZ... The monsoon trough extends from the coastal border of Liberia and Sierra Leone near 07N12W to 04N21W. The ITCZ stretches from 04N21W to 04N52W. Scattered moderate convection is observed from 02N to 10N between the W coast of Africa and 33W. GULF OF AMERICA... A stationary front extends from the Florida Everglades to 24N88W to 1013 low pressure just offshore Tampico, Mexico. A surface trough extends from this low southward to just offshore Veracruz, Mexico, and another extends northward along the Texas coast. N of the front and W of 90W, fresh SE winds are ongoing, with seas of 3 to 5 ft. Elsewhere, mainly gentle winds prevail with seas of less than 3 ft. For the forecast, the stationary front will lift northward tonight as the low over the NW Gulf strengthens. Moderate to locally fresh southerly winds over the western Gulf will spread eastward tonight into Thu. Then, another cold front will enter the NW waters on Thu, and extend from SE Louisiana to near Tampico, Mexico Fri morning, then stall and also lift north toward the northern Gulf on Sat. Looking ahead, a stronger cold front is likely to sweep across the Gulf region late Sun into Mon, bringing fresh to strong NW to N winds over much of the basin. This front CARIBBEAN SEA... A robust surface trough along 64W is inducing numerous moderate convection along and E of it back into the Atlantic. In addition, fresh to strong E winds are present in the SE Caribbean to the E of the trough. Fresh trades are ongoing offshore Colombia and in the Windward Passage, otherwise NE to E winds are moderate or weaker across the basin. Seas are 5 to 7 ft in the SE Caribbean and offshore Colombia, and 2 to 4 ft elsewhere. For the forecast, building high pressure north of the Caribbean Sea will support moderate to fresh easterly winds over much of the basin starting Thu and continuing into early next week. Meanwhile, moderate to locally rough seas, in NE swell, will persist across the NE Caribbean passages through the week and into the weekend. A surface trough, currently located near 64W, will continue to move westward across the eastern Caribbean through tonight before dissipating. Fresh to strong winds and locally rough seas are noted in the wake of this trough. The associated moisture is producing some shower activity and isolated thunderstorms across much of the Lesser Antilles. Looking ahead, a cold front may approach the NW Caribbean early next week. ATLANTIC OCEAN... See Special Features section above for information on a Gale Warning in the far eastern Atlantic, offshore Morocco. A cold front extends from Bermuda to near Miami, Florida. A pre- frontal trough is noted from 28N70W to the Florida Straits. Another trough is farther east, with an axis from 30N63W to just N of Hispaniola. No significant convection is occurring with any of these features, and winds and seas for waters W of moderate or weaker. Much of the remaining Atlantic is dominated by ridging stemming from a 1031 mb high near 35N27W. The pressure gradient between this high and lower pressures in the tropics result in fresh to locally strong NE to E winds and seas of 7-11 ft occurring across much of the Atlantic between 10N and 30N and E of 60W. The two exceptions are near the Cabo Verde Islands and a region N of 24N between 40W and 55W where moderate to fresh winds and moderate seas prevail. For the forecast west of 55W, the cold front will extend from E of Bermuda to central Cuba by Thu morning, and from 31N55W to eastern Cuba by Fri morning while dissipating. High pressure will follow the front. Then, a ridge will dominate most of the forecast area through the end of the week. The next cold front is expected to clip the waters offshore of NE Florida during the upcoming weekend, with a stronger cold front reaching the same area on Mon. $$ Konarik
