000 AXNT20 KNHC 072300 TWDAT Tropical Weather Discussion NWS National Hurricane Center Miami FL 0005 UTC Tue Mar 8 2022 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 1800 UTC surface analysis and satellite imagery through 2210 UTC. ...MONSOON TROUGH/ITCZ... The monsoon trough extends from the African coast along the border of Liberia and Cote d'Ivoire near 08.5N08W to 04.5N14W. The ITCZ continues from 04.5N14W to the equator along 30W to 01N41W to the coast of Brazil near 00S50W. Scattered to locally numerous moderate to strong convection is noted S of 04N between 17W and 43W. GULF OF MEXICO... The majority of the basin is dominated by a moderate southeasterly breeze and moderate wind seas of 4 to 6 ft. Fresh easterly winds in the Florida Straits this morning have veered to SE this afternoon, where seas are 5-7 ft. A cold front has entered the NW Gulf today and moved SSE off the Texas coast, and extends from SE Louisiana to the upper Mexican coast just south of the Texas border. Strong northerly winds are building behind the front. Seas have built as high as 8-11 ft offshore of the SE Texas coast in recent hours. Scattered moderate convection is within 60 nm SE of the cold front across the Louisiana coastal waters. Fresh to strong winds are expected behind the cold front through tonight while the boundary is forecast to stall from the Florida Panhandle to the Bay of Campeche. The stationary front will then linger across the area through midweek and then gradually dissipate by Thu. Seas will peak around 10 ft tonight behind the front across the Mexican offshore waters. CARIBBEAN SEA... Moderate to fresh easterly winds dominate the central and eastern Caribbean. Areas of strong winds are noted in the Windward Passage, to the south of Hispaniola, and along the coast of Colombia. Seas are generally 6-8 ft and up to 9 ft near Colombia. Conditions are more favorable with in the NW Caribbean with moderate E to SE winds and 4-5 ft seas. High pressure north of the area will support fresh to strong trade winds in the south-central Caribbean through Thu night, in the Windward Passage through tonight, and south of Hispaniola through Tue. Moderate to fresh trades, along with 8 to 9 ft seas in persistent northeast to east swell, will continue to impact the waters east of the Lesser Antilles through the upcoming weekend. ATLANTIC OCEAN... The weather pattern is dominated by a broad ridge along 32N-33N, and centered on a 1029 mb high east of Bermuda near 32N59W. Surface ridging extends W from the high to northern Florida, with mainly moderate anticyclonic winds north of 26N and west of 65W. The pressure gradient increases south of 26N in the western Atlantic, with buoys reporting fresh to strong easterly winds. High seas up to 11 ft are observed east of the Bahamas. In the central Atlantic, the tail end of a cold front extends from 31N25W to 28.5N42W where a shearline continues to 27N50W. Scatterometer satellite data recently showed moderate to fresh NE winds behind these features. South of 26N, a large area of moderate to fresh easterly winds is generating rough seas of 8-10 ft across the majority of the tropical Atlantic. For the forecast west of 65W, high pressure over the western Atlantic will shift eastward and gradually weaken the next couple of days. This will diminish the fresh to strong easterly winds and easterly swell across the offshore waters to the east of the Bahamas through Tue morning. Fresh to locally strong southerly flow is forecast for the NE Florida offshore waters Tue night to Wed night, resuming and expanding in areal coverage Fri night ahead of the next cold front. $$ Stripling
