884 AXNT20 KNHC 122156 TWDAT Tropical Weather Discussion NWS National Hurricane Center Miami FL 0015 UTC Thu Nov 13 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 1800 UTC surface analysis and satellite imagery through 2140 UTC. ...SPECIAL FEATURES... Significant Rainfall over Central America: A frontal boundary has stalled from the Turks and Caicos Islands, southwestward across extreme eastern Cuba to the N coast of Honduras. Fresh to strong N to NE winds prevail north of the front. This scenario is producing strong and moist onshore flow, particularly into the northern coast of Honduras and NE Nicaragua, leading to scattered showers and thunderstorms. Scattered moderate to strong convection is occurring in the western Caribbean, generally west of 80W and south of 18N. A middle to upper level ridge will extend into the W Caribbean and Central America by Thursday, weakening the frontal boundary and leading to less precipitation over eastern Honduras. The boundary will then slowly move northward, leading to heavy precipitation over northern Belize and southern Quintana Roo-Mexico from Thursday into Friday morning. Meanwhile, a lower level trough will continue to produce heavy precipitation over Nicaragua and Costa Rica through Friday, with the heaviest rainfall occurring during the afternoon hours on Thursday and Friday. This rainfall is likely to result in 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. Agadir Gale Warning: The pressure gradient between a strong stationary low in the NE Atlantic and higher pressures over N Africa and N Italy will lead to sustained strong to near-gale force SW winds offshore Agadir later this evening and overnight. Gusts exceeding gale force can be expected, and Meteo-France has issued a Gale Warning for the Agadir zone from 13/03 UTC through at least 13/18 UTC. For more information, please refer to Meteo-France`s website at: http://wwmiws.wmo.int/index.php/metareas/display/2. ...MONSOON TROUGH/ITCZ... The monsoon trough extends from 11N16W to 09N35W to 07N40W. The ITCZ continues from that point to 06N55W. Scattered moderate convection is occurring from 06N to 09N and E of 20W. ...GULF OF AMERICA... A ridge extends from 1028 mb high pressure over the northeastern Gulf near 29N87W toward Tampico, Mexico. A recent scatterometer satellite pass indicated fresh S winds north of ridge along the coast of Texas, and fresh to strong NE winds over the Straits of Florida. Gentle to moderate breezes are noted elsewhere. Wave heights are 5 to 7 ft over the south-central Gulf and 3 to 5 ft elsewhere, except for 1 to 3 ft in the far northeast Gulf. For the forecast, moderate to occasionally fresh NE winds and moderate seas will occur over the southeastern Gulf, including over the Florida Straits, through late Fri as a moderate pressure gradient prevails between a stalled front in the northwestern Caribbean and western Atlantic, and high pressure over the northeastern Gulf. Elsewhere, moderate to occasionally fresh S to SE winds are expected over the northwestern basin each afternoon and night through this weekend. Over the remainder of the Gulf, gentle to moderate winds and slight to locally moderate seas will prevail through the weekend. ...CARIBBEAN SEA... Please refer to the Special Features section above for details on convection associated with the significant rainfall event over the next couple of days across Central America and adjacent waters. A stationary front extends from extreme eastern Cuba to Puerto Barrios, Guatemala. Recent scatterometer data from 15-16 UTC indicated fresh to strong NE winds occurring behind the front and across much of the northwest Caribbean. Fresh to strong E winds are also occurring across the central Caribbean, strongest offshore northwest Colombia. Wave heights west of 70W are 6 to 9 ft, and 5 to 7 ft east of 70W. For the forecast, fresh to strong NE winds will occur over the central and northwestern Caribbean through Thu morning as a frontal boundary stalls over the region. Widespread rough seas are expected over this area, with locally very rough seas possible in the Gulf of Honduras. Winds and seas will slowly diminish Thu night into early Fri as the front dissipates, though locally fresh NE winds may continue to pulse in the lee of Cuba and in the far south-central Caribbean into Sat. Heavy rainfall will continue over the southwestern through west-central Caribbean and coastal zones through Fri, from the southeastern Yucatan Peninsula across Central America to Panama. Moderate trade winds and moderate seas will occur over the basin by this weekend. ...ATLANTIC OCEAN... A cold front extends from near 31N55W to 25N65W then becomes stationary through the Turks and Caicos Islands and across extreme eastern Cuba. Scattered showers are occurring in the vicinity of the front. The subtropical ridge will extend along 28N/29N west of the front. Fresh NE winds are noted between the front and the ridge south of 27N, with gentle to moderate breezes elsewhere of the front. Wave heights are 8 to 12 ft in NW swell west of the front to 74W, and 5 to 7 ft elsewhere west of 74W. Farther east, a front reaches from near Madeira to 24N30W to 1016 mb low pressure near 26N44W. Fresh to strong NW winds and 8 to 12 ft are noted north of this front. Gentle to moderate winds and 5 to 7 ft seas are noted elsewhere across the Atlantic. For the forecast west of 55W, fresh to locally strong NE winds will occur in the wake of the front north of the Greater Antilles to 25N through late tonight, with locally fresh winds continuing through late Fri night as the fronts slowly dissipate. Widespread rough seas will expand eastward into the central Atlantic through Thu, and very rough seas of 12 to 15 ft will be possible north of 25N between 55W and 67W through late tonight. Seas will diminish from northwest to southeast Thu into Fri. Elsewhere, a cold front pushing off the southeastern U.S. later today will lead to moderate to fresh W to NW winds and locally rough seas north of 29N this evening through Thu. The cold front will eventually dive southeastward in the central Atlantic by late week, supporting fresh W to NW winds and rough seas east of 70W by Thu night. Looking ahead, a series of cold fronts passing north of the region this weekend will lead to strengthening winds and building seas over the northern waters. $$ Christensen
