539 AXNT20 KNHC 100538 TWDAT Tropical Weather Discussion NWS National Hurricane Center Miami FL 0615 UTC Mon Nov 10 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 0530 UTC. ...SPECIAL FEATURES... Gulf of America Gale Warning: A strong cold front is moving over the Gulf waters, extending from 30N85W to 22N98W. The front will continue to move quickly SE through the basin and exit by Mon evening. 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 over the SW Bay of Campeche beginning at 0600 UTC tonight and prevailing through Mon night. Otherwise, there is a potential for gusts to gale force winds over the northern and western Gulf through Mon morning, and over the central, southern and eastern basin through late Mon night. Conditions will improve basin-wide by Tue evening. Western Atlantic Gale Warning: A strong cold front extending over the southeastern United States will emerge in the western Atlantic tonight. NW gales and very rough seas are expected N of 29N Mon night through Tue behind the front, with locations to the south having strong to near-gale force winds and rough seas after the front passes. The front will move SE and reach from Bermuda to eastern Cuba Tue, then extend from 31N55W to The Turks and Caicos by Wed. As the front weakens and stalls by the middle of the week, winds and seas will gradually diminish. For more information about these warnings, 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 early on Mon over the NW Caribbean Sea and Honduras, enhancing moisture convergence across Guatemala, Belize, Honduras, and Nicaragua. The shearline will move south on Monday, and will interact with a surface trough off the coasts of Nicaragua and Costa Rica by Tuesday morning, resulting in enhanced moisture convergence. A 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 enters the Atlantic waters near 14N17W and continues southwestward to near 07N36W. The ITCZ then extends from that point to 05N52W. Scattered moderate convection is occurring from 04N to 14N and E of 40W. ...GULF OF AMERICA... Please see the SPECIAL FEATURES section for additional information on the Gale Warning in the SW Gulf. Strong to near-gale force winds are occurring over the northern and northwestern Gulf along and behind the cold front. Moderate N to NW winds are noted over the rest of the basin. Scattered showers and thunderstorms are occurring across the Bay of Campeche, mainly S of 10N. Rough seas are noted north of the front, with slight seas occurring elsewhere in the basin. For the forecast, the cold front will race southeast tonight and exit the basin Mon. Strong to near gale-force N to NE winds and rough to very rough seas can be expected behind the front, with gale force winds and very rough seas offshore of Veracruz Mon morning into Mon night. Gales are also anticipated tonight offshore Tampico. Conditions will improve basin-wide by Tue evening as high pressure settle southward into the region. ...CARIBBEAN SEA... Please refer to the section above for details on the significant rainfall event expected across Central America and adjacent waters this week. The eastern end of the Pacific Monsoon Trough is supporting scattered moderate convection, across the offshore waters of Honduras, Nicaragua, Costa Rica, and Panama. A surface trough extends over western Hispaniola into the central Caribbean near 15N74W, and scattered showers and thunderstorms are occurring near this trough. Otherwise, a prevalent ridge extending across the basin continues to tighten the gradient across the eastern and central Caribbean, thus supporting the continuation of fresh trades and moderate seas in these regions. Strong winds have developed offshore of northwestern Venezuela and northern Colombia. Moderate or weaker trades are ongoing in the NW basin with slight seas. For the forecast, strong winds and rough seas are expected in the south-central Caribbean through Mon night. Rough seas in east swell over the tropical Atlantic waters east of the Lesser Antilles will gradually subside through Mon night. A strong cold front will enter the NW Caribbean waters on Mon, bringing strong to near-gale force N winds and rough seas in its wake. The front will stall from eastern Cuba to eastern Honduras Tue and gradually weaken through Wed evening. Aside from the strong winds and seas, the front will support the development of heavy rainfall and thunderstorms over Central America and adjacent waters through at least Thu. ...ATLANTIC OCEAN... Please refer to the section above for details on the Gale Warning in effect for the W Atlantic beginning on Mon night. A surface trough extends from 31N78W southwestward through central Florida. Scattered showers and isolated tstms are ongoing along the trough, mainly W of 75W. To the east, The surface trough over W Hispaniola also extends over the southern Bahamas, inducing scattered showers and isolated thunderstorms S of 22N between 69W-72W. The remainder of the subtropical Atlantic is under the influence of the Azores High that is anchored by a pair of 1028 mb highs N of the area. Moderate to fresh NE to E winds dominate the open Atlantic waters. A long-period NW swell is supporting rough seas N of 17N and E of 50W. Farther south, rough seas in E swell prevails east of the Lesser Antilles. For the forecast west of 55W, the areal extent of strong SW winds offshore NE Florida will increase in the next couple of hours, ahead of a strong cold front that will push off the SE U.S. late tonight. The front will move SE and reach from Bermuda to eastern Cuba Tue, then extend from 31N55W to The Turks and Caicos by Wed. NW gales and very rough seas are expected N of 29N Mon night through late Tue behind the front, with locations to the south having strong to near-gale force winds and rough seas after the front passes. As the front weakens and stalls by the middle of the week, winds and seas will gradually diminish. $$ ERA
