000 AXNT20 KNHC 291723 TWDAT Tropical Weather Discussion NWS National Hurricane Center Miami FL 1805 UTC Mon Jan 29 2024 Tropical Weather Discussion for North America, Central America Gulf of Mexico, 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 1200 UTC surface analysis and satellite imagery through 1600 UTC. ...MONSOON TROUGH/ITCZ... A monsoon trough remains mostly over the African Continent. An ITCZ extends westward from 05N17W through 05N38W to east of Amapa State, Brazil at 03N47W. Widely scattered to scattered moderate convection is seen up to 80 nm north, and 120 nm south of the ITCZ. ...GULF OF MEXICO... A surface ridge reaching southeastward from a 1029 mb high over southern Texas to the Florida Straits is promoting fair weather for the entire Gulf. Gentle N to NE winds and seas of 3 to 5 ft are present at the northwestern Gulf. Moderate with locally fresh N winds and 5 to 7 ft seas prevail for the rest of the Gulf. For the forecast, a weak cold front will move across the northeastern Gulf Tue night through Wed night and bring fresh NW winds. Aside from that, quiescent marine conditions will prevail for the next several days over the Gulf as high pressure dominates. ...CARIBBEAN SEA... A cold front extends southwestward from central Cuba across the Cayman Islands to the Gulf of Honduras. Scattered showers are seen up to 80 nm along either side of this feature. A surface trough embedded within the trade-wind flow is generating similar conditions at the central basin. Fresh to strong northerly winds and seas at 6 to 8 ft are evident behind this front, including the Yucatan Channel. Fresh with locally strong NE winds and 6 to 8 ft seas are found offshore from northwestern Colombia. Gentle to moderate NE to ESE winds and 4 to 6 ft seas prevail elsewhere in the Caribbean Basin, including the Windward Passage. For the forecast, fresh to strong N winds behind the cold front will continue through Tue as it moves southeastward until dissipation Tue night. A moderate pressure gradient across the central Caribbean will induce fresh to locally strong NE winds late night and early morning hours north of Colombia through Fri. Elsewhere, winds should be quiescent for the next several days. ...ATLANTIC OCEAN... A cold front curves southwestward from west of Bermuda across 31N69W and the central Bahamas to beyond central Cuba. Scattered showers and isolated thunderstorms are occurring up to 60 nm along either side of this boundary. Two surface troughs are producing scattered showers north of the Leeward Islands from 22N to 28N between 59W and 64W, and farther east from 20N to 24N between 46W and 55W. Convergent trades are inducing similar conditions near the Lesser Antilles. Another surface trough is causing scattered showers and isolated thunderstorms near the coast of French Guiana and Amapa State of Brazil. Refer to the Monsoon Trough/ITCZ section for additional weather in the Atlantic Basin. Fresh to strong with locally near-gale SW to NW winds and seas of 8 to 13 ft are evident near and behind the cold front from the northwest Bahamas northward. Moderate to fresh SW to W winds and 6 to 8 ft seas are noted farther south from 25N to the cold front between 65W and the central Bahamas. Moderate to fresh SE to S winds and seas at 5 to 7 ft are present farther east, north of 20N between 57W and the cold front. For the central and eastern Atlantic, a large dome of 1025 mb high near 26N42W is providing light to gentle winds and 4 to 6 ft seas in moderate northerly swell north of 18N between the northwest Africa coast and 57W, including the Canary Islands. Near the Cabo Verde Islands, gentle to moderate NE trades with seas at 4 to 6 ft are seen from 05N to 18N between the central Africa coast and 35W. For the tropical Atlantic, moderate to fresh NE to E trades and seas of 6 to 8 ft exist from 05N to 20N between 35W and the Lesser Antilles. Light to gentle winds and 3 to 6 ft seas in mixed swells prevail for the remainder of the Atlantic Basin. For the forecast W of 55W, the aforementioned cold front will reach from 31N60W to Hispaniola Tue morning and from 22N55W to Puerto Rico Wed morning. Peak winds ahead and behind the front are strong to near-gale north of 25N, which will gradually diminish as the front continues eastward for the next two days. A developing extratropical low will exit the Carolinas coast Wed and move along our 31N border through Fri. Strong to near-gale west winds are anticipated mainly north of 25N Wed night into Fri. $$ Chan
