335 AXNT20 KNHC 090547 TWDAT Tropical Weather Discussion NWS National Hurricane Center Miami FL 0615 UTC Sun Nov 9 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 0600 UTC. ...SPECIAL FEATURES... Gulf of America Gale Warning: A strong cold front will move into the NW Gulf late tonight, then quickly move SE through the basin and exit Mon. Strong to near gale-force N to NE winds and rough seas can be expected behind the front, with gale force winds and very rough seas offshore of Veracruz Mon. Gale force winds are forecast to begin at 10/1200 UTC, along with seas up to 12 ft. For more information, please see the latest HIGH SEAS FORECAST issued by the National Hurricane Center at website: https://www.nhc.noaa.gov/text/MIAHSFAT2.shtml for more information. Significant Rainfall over Central America: A shearline is expected to form Sunday afternoon over the northwest Caribbean Sea and Honduras, enhancing moisture convergence across Guatemala, Belize, Honduras, and Nicaragua. The shearline will continue moving south on Monday, and will interact with a developing low off the coasts of Nicaragua and Costa Rica by Tuesday morning, resulting in enhanced moisture convergence. A potent cold front will then arrive in Guatemala, Honduras, and Belize on Tuesday morning, after which it will become stationary and linger across the region through Thursday. Significant rainfall over the course of several days will be possible as a result, and will raise concerns for life-threatening flash flooding and landslides. This information was provided by the International Desk at the Weather Prediction Center. Please refer to your local meteorological service for more details. ...MONSOON TROUGH/ITCZ... The monsoon trough is analyzed inland over Africa. The ITCZ extends from 12N16W to 01N50W. Scattered moderate convection is occurring from 03N to 15N between the coast of Africa and 46W. GULF OF AMERICA... Ridging extends over the basin, supporting moderate or weaker S to SW winds and 1 to 3 ft seas. No notable convection is occurring across the basin. For the forecast, a strong cold front will move into the NW Gulf late tonight, then quickly move SE through the basin and exit Mon. Strong to near gale-force N to NE winds and rough seas can be expected behind the front, with gale force winds and very rough seas offshore of Veracruz Mon. There is a potential for gust to gale force winds for the NW Gulf beginning Sun morning and continuing through Mon morning. Conditions will improve basin- wide by Tue evening. CARIBBEAN SEA... The persistent surface trough in the western Caribbean continues to support scattered moderate convection, mainly within 90 nm of the coasts of Honduras, Nicaragua, Costa Rica, and Panama. Moderate to fresh trades and 3-6 ft seas prevail across the eastern and central Caribbean, with fresh to strong winds occurring offshore NW Colombia. In the NW Caribbean, gentle to moderate winds and 1-3 ft seas prevail. For the forecast, locally strong winds and rough seas are expected in the south-central Caribbean through Mon. Rough seas in N swell will continue over the tropical Atlantic waters east of the Lesser Antilles into Mon and then will gradually subside into Tue. A strong cold front will move into the NW Caribbean Mon, bringing strong to near gale force N winds and rough to very rough seas in its wake. The front will stall over the middle of next week from eastern Cuba to eastern Honduras. Showers and thunderstorms along and ahead of this front will also bring a potential for heavy rainfall for much of next week over Central America, particularly Honduras. ATLANTIC OCEAN... A surface trough in the western Atlantic extends from 31N70W to the central Bahamas, and scattered showers and thunderstorms are occurring to the east of this feature, generally north of 25N and west of 60W. Moderate to locally fresh S to SW winds and 4 to 6 ft seas are occurring in this area as a storm system centered north of the region strengthens. West of 70W, light to gentle winds and 2 to 4 ft seas prevail. Fresh to strong trades prevail across much of the Atlantic between 05N and 25N between the W coast of Africa and 62W, with moderate to fresh trades elsewhere across the open Atlantic. East of 60W, NW swell with periods of 12-16 seconds continues to propagate across most of the basin, with seas of 7-11 ft. For the forecast west of 55W, moderate to fresh S to SW winds developing offshore of NE Florida Sun morning will reach fresh to strong speeds Sun night into Mon ahead of a strong cold front that will push off the SE U.S. Sun night. The front will progress SE and reach from Bermuda to E Cuba Tue afternoon, with the southern portion of the front stalling from 27N63W to E Cuba Tue night into Wed. Strong to gale-force winds and rough to very rough seas are expected behind the front through Tue evening. Gale conditions in W to NW winds are expected along and N of 30N Mon night into late Tue, especially W of 65W. Winds then will gradually diminish through Wed. $$ Adams
