000 AXNT20 KNHC 261726 TWDAT Tropical Weather Discussion NWS National Hurricane Center Miami FL 1805 UTC Sun Nov 26 2023 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 1710 UTC. ...MONSOON TROUGH/ITCZ... The monsoon trough extends from the coast of Sierra Leone near 08N13W to 04N25W. The ITCZ continues from 04N25W to the coast of Brazil near 02N50W. Scattered moderate convection is from 01N to 05N between 13W and 17W. GULF OF MEXICO... At 1500 UTC, a cold front extends from South Padre Island, Texas to 1012 mb low pressure centered near 28.8N89.7W, with a warm front then continuing to Cedar Key, Florida. Recent surface observations indicate strong to near-gale force N winds across the Gulf waters north of the front, with strong to near-gale force S winds south of the front to 26N. Seas are 5-8 ft across the Gulf north of 26N. Scattered moderate convection is from 28N to 31N between 83W and 88W. Elsewhere, a weak surface trough is in the Bay of Campeche. In remaining waters, gentle southerly winds south of 24N increase to moderate to fresh speeds from 24N to 26N. Seas are 3-5 ft. For the forecast, the low will move E-NE and through the Florida Big Bend this afternoon and evening, and drag the cold front across the basin, reaching from the Florida Big Bend to Veracruz this evening, from near Fort Myers to the central Bay of Campeche Mon morning, and from western Cuba to the Yucatan peninsula and the eastern Bay of Campeche Tue morning. The front will move southeast of the basin Tue night as high pressure settles in over the region. Fresh to strong winds will follow the cold front, except in the SW Gulf where strong to near gale force winds are expected. CARIBBEAN SEA... Ridging across the Caribbean provides for gentle to moderate trades across the basin. The most recent satellite scatterometer data depicts an area of fresh trades in the south-central Caribbean, including the Gulf of Venezuela. Seas are 5-7 ft in the central Caribbean, and 3-5 ft in the eastern and western Caribbean. For the forecast, a weak Atlantic ridge will remain N of the basin through Tue and maintain moderate to fresh trade winds across the eastern and central Caribbean, while mainly gentle to moderate east to southeast winds will continue in the northwestern Caribbean. Fresh to strong winds in the south-central Caribbean near the coast of Colombia, and in the Gulf of Venezuela will continue through the forecast period. A cold front will sink into the NW Caribbean early Tue and gradually stall and weaken from central Cuba to northern Belize by Thu. ATLANTIC OCEAN... In the western Atlantic, a stationary front extends from Daytona Beach, Florida to 31N79W. Scattered showers are near this front. 1020 mb high pressure is near 29N75W, and 1019 mb high pressure is near 29N65W. In the central Atlantic, a cold front extends from 31N43W to 25N64W. Moderate to fresh SW winds are along the frontal boundary. Scattered moderate convection is from 25N to 30N between 43W and 49W. 1019 mb high pressure is south of the front near 23N55W. A surface trough is from 16N52W to 11N57W just east of the Lesser Antilles. In the eastern Atlantic, a surface trough extends from 31N28W to 26N31W. Light to gentle winds are north of 20N, with gentle to moderate trades south of 20N. Satellite altimeter data indicates 7-9 ft seas from 21N to 31N between 25W and 45W in subsiding N swell. An area of seas to 8 ft is from 08N to 10N between 49W and 52W. Elsewhere, seas are 4-7 ft. For the forecast W of 55W, the weak high pressure ridge along 29N will shift eastward through Mon, ahead of an approaching front in the Gulf of Mexico. This cold front is forecast to move off the northeast Florida coast on Mon, reach from near 31N65W to 26N70W and to the central Bahamas and western Cuba by Tue morning, then from near 30N55W to 25N70W by Wed morning and continuing as a stationary front across the central Bahamas and along the coast of western Cuba. The stationary front will lift back N as a warm front late Wed. Moderate to fresh winds are expected on either side of the front. High pressure will build eastward across the region Thu and Thu night. $$ Mahoney
