801 AXNT20 KNHC 252033 TWDAT Tropical Weather Discussion NWS National Hurricane Center Miami FL 0015 UTC Wed Nov 26 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 2030 UTC. ...MONSOON TROUGH/ITCZ... The monsoon trough enters the Atlantic near 09N13W and continues to 08N15W. The ITCZ extends from 08N15W to 07N20W to 08N35W to 07N50W. Scattered moderate convection is present from 07N to 09N between 18W and 23W. ...GULF OF AMERICA... A weak cold front extends from south-central Louisiana to South Texas near the mouth of the Rio Grande. A few showers and thunderstorms are active ahead of this front. A few additional showers and thunderstorms are active over the southwest Gulf along 95W from 21N to 25N, ahead of a trough over the Bay of Campeche and associated with the subtropical jet active near the area. Farther east, 1018 mb high pressure is centered near 27N86W. This pattern is supporting gentle to moderate SE to S winds and 2 to 4 ft seas across the basin. For the forecast, a stronger reinforcing cold front will overtake the aforementioned weak front early Wed while reaching from the western Florida Panhandle to 28N90W to NE Mexico. The cold front will then sweep to the southeast of the basin by Thu night into Fri, followed by fresh to strong northeast winds and building seas into the weekend. Scattered showers and thunderstorms may accompany the fronts. Moderate to fresh return flow under strong high pressure is forecast by Sat afternoon. Another front may move into the NW waters early Sun. ...CARIBBEAN SEA... High pressure north of the area continues to force fresh to strong easterly winds and rough seas in the central Caribbean. A recent scatterometer satellite pass indicated strong to near-gale force winds off the coast of Colombia, with mostly moderate to fresh trade winds elsewhere across the eastern and central Caribbean. A concurrent altimeter satellite pass indicated 8 to 11 ft seas near the strong to gale-force winds. Combined seas are 5 to 7 ft elsewhere over the eastern and central Caribbean. Gentle to moderate E winds and 3 to 5 ft are observed over the northwest Caribbean. Scattered showers and thunderstorms are active over the far southwest Caribbean from Panama to off Costa Rica. For the forecast, the tight pressure gradient between high pressure north of the basin and lower pressures over NW Colombia will sustain fresh to strong easterly trade winds and rough seas in the central Caribbean through early Fri. The strongest winds of 25 to 30 kt, and highest seas peaking near 12 ft are expected offshore Colombia mainly at night. In the remainder of the basin, the weather pattern will support moderate to fresh winds along with moderate seas through early Fri. Looking ahead, a cold front will slowly enter the NW Caribbean on Fri, followed by strong winds and rough seas through Fri night. The front may stall and wash out over the NW Caribbean by Sat with conditions gradually improving for the remainder of the weekend. ...ATLANTIC OCEAN... A weak cold front extends from near 31N52W to 28N70W, where it becomes a stationary front that extends to 28N78W. Moderate to fresh N to NE winds and 5 to 7 ft seas are active north of the front east of 65W. Moderate to fresh E winds and 5 to 6 ft seas are noted south of 25N between 65W and 75W, with moderate E to SE winds and 4 to 5 ft seas elsewhere east of 55W. Farther east, scattered showers and thunderstorms are active along a trough from 22N to 30N between 43W and 47W. Another trough is southwest of the Canary Islands from 20N28W to 27N23W. Numerous showers and thunderstorms are also active on the north of the trough from 26N to 28N between 20W and 25W. Fresh E winds and 5 to 8 ft seas noted north of the trough from 27N to 30N between 23W and 30W. Gentle to moderate NE winds and 4 to 6 ft seas are noted elsewhere east of 55W. For the forecast west of 55W, the eastern portion of the front will continue eastward and reach from 26N55W to 25N70W by early Wed, while the western portion dissipates. High pressure located off New England will shift eastward following the front, supporting moderate to fresh northeast to east winds and moderate seas over the region, locally rough near 55W. Looking ahead, winds and seas will diminish west of 70W by Wed, ahead of a stronger cold front expected to move off the northeast Florida coast Wed night. The front will reach from near Bermuda to the Straits of Florida by early Fri, followed by fresh to strong NW winds and building seas through Fri night. A tightened pressure gradient in the wake of the front is forecast to bring increasing winds and building seas across much of the forecast area Sat, gradually diminishing from west to east Sun. $$ Christensen
