009 AXNT20 KNHC 222256 TWDAT Tropical Weather Discussion NWS National Hurricane Center Miami FL 0015 UTC Sun Nov 23 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 2230 UTC. ...MONSOON TROUGH/ITCZ... The monsoon trough enters the Atlantic near 11N15W and continues southwestward to 09N19W, where it transitions to the ITCZ and continues to 07N58W. Scattered moderate to isolated strong convection is noted from 03N to 15N and E of 44W. ...GULF OF AMERICA... A 1019 mb high pressure is centered near 27N89W. The pressure gradient in the area is allowing for mostly light to gentle anticyclonic winds across the basin, except for gentle to moderate northeast to east winds south of about 23N and east of 94W. Seas are in general 2 to 4 ft, except 1 to 2 ft in the NE Gulf. A frontal boundary is along the coast of Texas generating scattered showers and thunderstorms N of 26N and W of 94W. For the forecast, the front will shift southeastward across the northern Gulf Sun, stall late Sun and Mon, then lift northward Tue. Expect fresh southerly flow off the Texas coast Sun night through Mon night between low pressure over northeast Mexico and high pressure over the Carolinas. These winds will diminish Tue ahead of another front moving across the southern Plains. Looking ahead, this stronger front will move into the northwest Gulf Wed, then sweep to the southeast of the basin by late Thu, followed by fresh NE winds and building seas. ...CARIBBEAN SEA... The combination between high pressure north of the area over the western Atlantic and the Colombian low is resulting in fresh to strong trade winds over most of the central Caribbean as captured by a recent scatterometer pass. Seas are 6 to 8 ft with these winds. Moderate to fresh winds and moderate seas are noted over the remainder of the basin. Scattered showers and thunderstorms are noted over the western section of the sea, mainly between 80W-86W. For the forecast, fresh to strong northeast to east winds will pulse offshore of northern Colombia each night and morning through the middle of next week as low pressure prevails over the south- central Caribbean. These winds will bring rough seas to the waters near northwest Colombia. Elsewhere, high pressure centered over the western Atlantic will support moderate to fresh trade winds and moderate seas over the rest of the basin through early next week. ...ATLANTIC OCEAN... A cold front is anaylzed from near 31N58W southwestward to 26N66W. No significant convection is associated with this front. Mainly light to gentle winds and slight to moderate seas are on either side of the front. Otherwise, high pressure dominates the remainder of the western Atlantic, with a 1020 mb high pressure situated near the NW Bahamas. Recent scatterometer satellite data passes depict moderate to fresh northeast to east winds south of about 23N west of 71W, including through the passages of the Bahama Islands. These winds reach to along the coast of Cuba and through the Straits of Florida. Over the central Atlantic, a trough extends from near 30N51W to 20N53W. An upper-level low is near 25N53W. This feature is providing upper support for the low/trough. Scattered to numerous showers and thunderstorms are E of the trough axis to about 43W. The pressure gradient between strong high pressure of 1031 mb situated to the northeast of the Azores and lower pressures over NW Africa is producing an area of fresh to strong northeast to east winds N of 27N and east of 25W, including the N waters of the Canary Islands. Seas of 8 to 10 ft in northeast to east swell are over this area. Moderate to fresh southeast to south winds are north of 25N between 40 and 45W or between the the trough and the SW periphery of the Azores high pressure. Seas are 8 to 10 ft with these winds. Otherwise, mostly moderate to fresh trades, with moderate seas are present over the rest of the tropical Atlantic. For the forecast west of 55W, the front over the W-central Atlantic will shift eastward then stall and dissipate through Sun. High pressure off east-central Florida will dissipate through Sun, ahead of another weak cold front that will move off the northeast Florida coast early Sun. The front will reach from Bermuda to Sebastian Inlet, Florida by early Mon. The eastern portion of the front will continue eastward and reach from 30N55W to 27N70W by early Tue, while the portion west of 70W starts to lift northward. High pressure will build north of the front off the Carolina coast, supporting moderate to fresh NE to E winds and moderate seas across the region, with large NW swell following the front southeast of Bermuda. Looking ahead, winds and seas will diminish west of 70W by Wed, ahead of front expected to move off the northeast Florida coast early Thu. The front will reach from Bermuda to the Straits of Florida by late Thu night, followed by fresh NE winds and building seas. $$ ERA
