000 AXNT20 KNHC 312252 TWDAT Tropical Weather Discussion NWS National Hurricane Center Miami FL 0005 UTC Sun Mar 31 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 1800 UTC surface analysis and satellite imagery through 2100 UTC. ...MONSOON TROUGH/ITCZ... A monsoon trough enters the Atlantic Ocean at the coast of Guinea just north of Conakry, then extends southwestward to 02N17W. An ITCZ continues from 02N17W to beyond 00S22W. Numerous moderate to isolated strong convection is noted near the ITCZ from the Equator to 03N between 18W and 25W. No significant convection is seen near the monsoon trough. ...GULF OF MEXICO... Weak surface ridging centered NE of the basin is dominating the weather, with gentle SE flow over the northeast Gulf evolving to moderate to fresh in the SW Gulf. Locally strong E winds have developed offshore the northern Yucatan. Seas are 3 ft or less in the NE Gulf, and 3 to 5 ft in the SW. For the forecast, fresh to occasionally strong E to SE winds will prevail across the western Gulf through Mon. A cold front will enter the western Gulf on Tue. The front will extend from the Florida panhandle to the Bay of Campeche Wed, and will move SE of the area Thu. Fresh to strong winds and building seas are expected west of the front. Winds and seas will decrease Thu and Fri as high pressure builds in the wake of the front. ...CARIBBEAN SEA... A surface trough from Hispaniola to just SE of Jamaica is trigger scattered moderate convection. Convection previously associated with a weaker trough moving W into the Gulf of Honduras has dissipated. Otherwise, mainly moderate to fresh trades dominate the basin, with seas of 4 to 6 ft. Fresh NE winds are ongoing offshore Colombia and in the Windward Passage. Seas in these locations are 6 to 8 ft. Also, northerly swell is propagating through Atlantic passages near Puerto Rico and the Virgin Islands, inducing similar seas of 6 to 8 ft. For the forecast, high pressure north of the region will support pulsing of fresh to strong NE winds in the lee of eastern Cuba, across the Windward Passage, and off the southern coast of Hispaniola through Tue. Strong trade winds and rough seas will pulse off the coast of Colombia through the middle of the week. Winds and seas will then decrease by the second half of the week as the area of high pressure shifts eastward and further from the area. ...ATLANTIC OCEAN... A cold front curves southwestward from the north-central Atlantic across 31N37W to 21N46W. Scattered moderate convection occurring near and up to 150 nm east of the front. A surface trough extending NE from the Leeward Islands to 22N55W has weakened and associated convection has diminished. Otherwise, the basin is dominated by a pair of high pressure centered, one 1024 mb located near 27N68W and another 1020 mb focused at 27N30W. Ahead of the aforementioned cold front, fresh S winds are ongoing N of 25N and W of 33W. Behind the front, a 150 nm band of moderate to fresh NE winds prevail, with the high pressure back E of the Bahamas leading to a broad area of gentle winds. NW of this high, along 30N to the W of the Bahamas, increasing moderate to fresh return flow has developed. Elsewhere ahead of the front, the other high pressure centered is inducing gentle winds N of 20N. To the south, mainly moderate trades dominate the waters W to the Lesser Antilles. To the E of 35W, rough seas E of 65W will subside from west to east through Mon. A cold front will move off the coast of Florida on Wed. This front will extend from near Bermuda to W Cuba Thu, and from near 31N58W to central Cuba Fri. Increasing winds and building seas will be both ahead and behind this front, mainly N of 25N. For the forecast west of 55W, rough seas E of 65W will subside from west to east through Mon. A cold front will move off the coast of Florida on Wed. This front will extend from near Bermuda to W Cuba Thu, and from near 31N58W to central Cuba Fri. Increasing winds and building seas will be both ahead and behind this front, mainly N of 25N. $$ Konarik
