055 AXNT20 KNHC 081038 TWDAT Tropical Weather Discussion NWS National Hurricane Center Miami FL 1215 UTC Sat Nov 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 0600 UTC surface analysis and satellite imagery through 1030 UTC. ...MONSOON TROUGH/ITCZ... The monsoon trough enters the Atlantic through the coast of Africa near 12N16W and continues southwestward to near 10N18W, where it transitions to the ITCZ, which extends to 07N30W to 02N45W. Scattered moderate convection is along and within 210 nm of both the ITCZ and monsoon trough. The eastern extension of the East Pacific monsoon trough extends across the far SW Caribbean. Scattered moderate convection is occurring as a result over the offshore waters of Panama and Costa Rica. ...GULF OF AMERICA... A weak ridge dominates the entire Gulf, which is supporting moderate or weaker winds and slight seas. Otherwise, a mid-level short-wave trough supports scattered showers over the Florida Big Bend offshore waters. For the forecast, moderate or weaker winds and slight seas will prevail basin-wide through this evening. A strong cold front will move into the NW Gulf Sun morning and progress southeastward, exiting the basin Mon afternoon. Strong to near gale-froce N to NE winds and rough seas can be expected behind the front, and gale force winds and very rough seas are likely offshore of Veracruz Mon. Conditions will improve basin-wide by Tue evening. ...CARIBBEAN SEA... A surface trough in the W Caribbean is aiding in the development of scattered moderate convection across the offshore waters of E Honduras and Nicaragua. The pressure gradient between high pressure over the western and central Atlantic and the Colombian low is supporting fresh to strong trades over the south-central Caribbean, and moderate to fresh trades elsewhere in the central and eastern basin. Light to gentle winds are over the NW Caribbean. Seas are moderate, except slight in the NW Caribbean. For the forecast, moderate to fresh trade winds will prevail over the central and eastern Caribbean through Tue, as a surface trough moves westward through the region, and high pressure builds to the north. Locally strong winds and rough seas are expected in the south-central and portions of the north-central Caribbean during the weekend and on 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 through late Tue. Looking ahead, a strong cold front is slated to enter the NW Caribbean late Mon, leading to widespread strong to near gale force N winds and rough seas in the wake of the front. The cold front is forecast to reach from E Cuba to E Honduras Tue evening where it will stall before it starts to weaken Tue night into Wed. ...ATLANTIC OCEAN... A weakening stationary front extends from 31N41W to 26N57W where it starts to dissipate. Mid to upper level diffluent flow support scattered heavy showers and isolated tstms N of the front or 26N between 50W and 75W. The remainder subtropical Atlantic is under the influence of the Azores-Bermuda High, which is supporting moderate or weaker winds W of 40W and moderate to fresh NW to E winds E of 40W. Otherwise, large N swell is supporting a broad area of 8 to 12 ft seas across the central and eastern Atlantic, with 8 to 9 ft seas extending across the tropical waters between the Cape Verde Islands and the Lesser Antilles offshore waters. For the forecast west of 55W, large NW swell to 12 ft will continue to impact the central Atlantic subtropical waters today before subsiding this evening. 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 near gale force winds and rough to very rough seas are expected behind the front through Tue night. $$ Ramos
