332 AXNT20 KNHC 080616 TWDAT Tropical Weather Discussion NWS National Hurricane Center Miami FL 0615 UTC Mon Dec 8 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 0500 UTC. ...SPECIAL FEATURES... Gulf of America Gale Warning: A cold front has entered the northwestern Gulf, and will steadily sink southeastward through Monday night. Fresh to strong NW to N winds and rough seas are expected to follow behind the front across the western and north-central Gulf. These winds will reach near-gale to gale-force off Veracruz Mon afternoon through late Mon evening. Afterward, winds and seas will gradually diminish Tue into Wed as the front stalls across the entrance to the Yucatan Channel and Straits of Florida, and high pressure settles across the central Gulf. Please refer to the latest High Seas and Offshore Waters Forecasts issued by the National Hurricane Center at the website https://www.nhc.noaa.gov/text/MIAHSFAT2.shtml and https://www.nhc.noaa.gov/marine/offshores.php for more details. ...MONSOON TROUGH/ITCZ... A monsoon trough enters the Atlantic through the coast of southern Sierra Leone to 06N15W, then extends southwestward to 06N16W. An ITCZ continues from 06N16W to 04N23W to 04N45W. Scattered moderate to isolated strong convection is noted from 02N to 19N between 22W and 31W. The eastern end of the East Pacific monsoon trough is causing isolated thunderstorms across the Caribbean waters near Panama and northwestern Colombia. ...GULF OF AMERICA... Please see the SPECIAL FEATURES section above for information on upcoming gale conditions expected offshore of Veracruz, Mexico. A cold front extends west-southwestward from a 1012 mb low over Tampa, Florida to west-central Gulf. Further west, another cold front curves southwestward from near New Orleans to beyond the coastal border of Texas and Mexico. Scattered showers and isolated thunderstorms are occurring near and up to 40 nm south of the first cold front. Scattered heavy showers and isolated thunderstorms are present offshore from Naples and Key West, Florida. Fresh to strong northerly winds and seas of 6 to 8 ft are present behind the second cold front across the northwestern Gulf. Moderate to fresh NE to SE to SW winds with 3 to 5 ft seas are seen at the east- central Gulf. Gentle to moderate NE to S to SW winds and 1 to 3 ft seas prevail for the rest of the Gulf. For the forecast, the second cold front will weaken further tonight as it drifts southeastward. The second cold front is expected to overtake the first front on Mon as it sweeps southeastward across the basin through Tue. This will lead to fresh to strong NE to N winds and building seas in the wake of this front. Winds may reach near gale level in the northwestern Gulf tonight into early Mon. Winds and seas will diminish Tue into Wed as the front stalls across the entrance to the Yucatan Channel and Straits of Florida, and high pressure settles across the central Gulf. Light to gentle winds and slight seas will persist late Wed through Fri night. ...CARIBBEAN SEA... Refer to the Monsoon Trough/ITCZ section for convection or weather in the Caribbean Sea. Moderate to fresh ENE to ESE winds and seas of 5 to 7 ft in the eastern and central basin. Light to gentle winds and seas at 2 to 5 ft prevail elsewhere in the Caribbean Sea. For the forecast, weak ridging north of the basin near 24N will support moderate to fresh trade winds and moderate seas east of 84W through Fri, except trades will become fresh to strong across the central Caribbean and the eastern part of the southwestern Caribbean starting late Tue night. Moderate or lighter winds and slight to moderate seas will prevail west of 84W. Long-period NE to E swell will support rough seas across the Atlantic waters and passages of the Lesser Antilles through Fri night. A weakening cold front is expected to approach the northwestern Caribbean on Tue and linger across the Yucatan Channel and Straits of Florida through Wed night before dissipating. High pressure will build across the eastern Gulf of America by the middle of next week, leading to strong winds and rough seas in the south-central Caribbean into late next week. ...ATLANTIC OCEAN... A warm front runs northeastward from central Florida to beyond 30N78W. Scattered heavy downpours and isolates Strong thunderstorms are noted up to 150 nm south of this front. Farther east, a surface trough near 28N70W is causing patchy showers up to 100 nm along either side of this feature. Convergent trade winds are generating scattered moderate convection near the coast of Guyana and Suriname. Refer to the Monsoon Trough/ITCZ section for additional weather in the Atlantic Basin. Gentle to moderate S to SW to W winds and seas at 3 to 6 ft north of 22N between 50W and the Florida/southern Georgia coast. At the eastern Atlantic, fresh to strong SW to W winds with 10 to 13 ft are evident north of 25N between 35W and 50W. Otherwise, light to gentle winds and 7 to 9 ft are seen from 20N to 25N. For the tropical Atlantic from 07N to 20N between 35W and the Lesser Antilles, moderate to fresh NE to E with 6 to 9 ft seas are noted. Gentle to moderate SE to SW winds and seas at 5 to 7 ft are prevail for the rest of the Atlantic Basin west of 35W. For the forecast west of 55W, fresh to locally strong winds and moderate to rough seas are near the front and east of 60W. These winds and seas will shift eastward tonight as the front dissipates. A complex low pressure system and strong cold front will move into the northwestern tropical Atlantic through Mon, supporting widespread strong to near gale-force winds north of 27N, and building seas ahead of and behind the front Mon through Tue evening. The cold front will reach from near Bermuda to the northwest Bahamas and Straits of Florida Tue afternoon, then gradually weaken and stall along about 26N early Wed as the low pressure shifts well NE of the area. Large north swell will move into the regional waters Tue through Wed then diminish Wed night. $$ Chan
