759 AXNT20 KNHC 041007 TWDAT Tropical Weather Discussion NWS National Hurricane Center Miami FL 1215 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 0600 UTC surface analysis and satellite imagery through 1005 UTC. ...MONSOON TROUGH/ITCZ... The monsoon trough extends from Sierra Leone near 08N13W to 06N20W. The ITCZ stretches from 06N20W to 05N53W. Scattered moderate convection is present from south of 10N and east of 30W. GULF OF AMERICA... A warm front extends from a 1013 mb low pressure centered over the central Texas coast to the eastern Gulf waters. Moderate to fresh easterly SE-E winds are found in the western and central Gulf, along with moderate seas. Elsewhere, moderate or lighter winds and slight to moderate seas prevail. For the forecast, moderate to fresh southerly winds over the western and central Gulf will diminish later today. A cold front will enter the NW waters this afternoon and fresh to strong N winds are expected in its wake. The front will 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 Sun into Mon, bringing fresh to strong NW to N winds over much of the basin. This front is forecast to move SE of the area late on Mon or Mon night. CARIBBEAN SEA... A few showers are evident over the eastern Caribbean, while generally fair conditions persist elsewhere. Moderate to locally fresh NE-E winds are found over much of the basin. Seas of 4-7 ft are present in the eastern, central and SW Caribbean, while slight seas prevail in the NW Caribbean. For the forecast, the subtropical ridge over the western Atlantic will gradually slide eastward, supporting moderate to fresh easterly winds over much of the basin through early next week. Locally strong NE winds may pulse at night off NW Colombia tonight. Meanwhile, locally rough seas, in NE swell, will persist across the NE Caribbean passages into early next week. Looking ahead, a cold front may approach the NW Caribbean early next week. ATLANTIC OCEAN... A stationary front extends from 31N67W to Miami, Florida. No significant convection is seen west of 60W. Moderate easterly winds and moderate seas are found south of 23N and west of 70W. Light to gentle winds and moderate to locally rough seas are present elsewhere west of 60W. Farther east, a surface trough and divergence aloft support numerous showers and isolated thunderstorms north of 26N and between 50W and 60W. The remainder of the central and eastern Atlantic sustain fresh to strong easterly winds and rough seas to 11 ft over much of the area, especially south of 25N. Elsewhere, moderate or lighter winds and moderate seas prevail. For the forecast west of 55W, the stationary portion of the front is likely to dissipate today into Fri, while the cold front, mainly north of our area, continues eastward. High pressure will follow the front. The next cold front is expected to clip the waters offshore of NE Florida late Fri into Sat, resulting in fresh to strong southerly winds and moderate to locally rough seas N of 28N and east of 70W. Conditions will improve Sun, but a stronger cold front reaching the same area on Mon. Fresh to strong winds and rough seas will develop north of 26N Mon and quickly shift eastward. Conditions will improve Tue. $$ Delgado
