000 AXNT20 KNHC 222353 TWDAT Tropical Weather Discussion NWS National Hurricane Center Miami FL 753 PM EDT Fri Mar 22 2019 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 32N. The following information is based on satellite imagery, weather observations, radar and meteorological analysis. Based on 1800 UTC surface analysis and satellite imagery through 2345 UTC. ...MONSOON TROUGH/ITCZ... The monsoon trough extends from the coast of Liberia near 04N08W to 01N12W. The ITCZ continues from 01N12W to 02S24W to the coast of Brazil near 06S34W. Scattered moderate convection is within 180 nm of the monsoon trough/ITCZ. GULF OF MEXICO... A 1024 mb high was located over the NW Gulf near 28N93W. No deep convection or any showers are present under the strong upper- level subsidence over the Gulf this afternoon. The surface winds veer clockwise around the high in a generally gentle to moderate breeze. Seas are well below 8 ft. High pressure along the SW Louisiana coast extends SE to the Gulf of Honduras this afternoon and will shift ENE into the W Atlc through the weekend. This will produce gentle to moderate winds through Sat morning before fresh SE return flow develops west of 92W Sat afternoon and evening. A cold front will sink southward across the northern Gulf waters Tue and reach the Yucatan Channel on Wed. Fresh N to NE winds are expected behind the front. CARIBBEAN SEA... A cold front extends from E Cuba near 19N76W to 14N80W. A surface trough continues from that point southwest to Nicaragua near 10N83W. Scattered showers are present within 60 nm n either side of the front. Across the Caribbean, isolated showers are occurring over E Cuba, Hispaniola and W Puerto Rico. E tradewinds over the Caribbean are generally gentle to moderate. The exception, as is typical, are winds just north of Colombia, which are up to fresh to strong NE breeze as observed by a scatterometer pass. Seas across the Caribbean remain below 8 ft. A cold front extending from eastern Cuba to near the Nicaragua- Costa Rica border will become stationary across Cuba while drifting SE across the SW Caribbean through Sat before it dissipates. Expect moderate to fresh N to NE winds behind the front through Sat. The remnants of the front will drift westward across the NW Caribbean as a trough through the weekend. Fresh to strong NE winds are expected along the coast of Colombia through Tue. N to NE swell from the Atlantic will move through the Caribbean passages E of Hispaniola this evening through late Sun. ATLANTIC OCEAN... A cold front extends from 32N59W southwestward to the eastern Bahamas and to E Cuba near 20N75W. Scattered showers are present within 60 nm of the front. A trough extends from 32N69W to 25N74W. SW winds north of 27N ahead of the cold front are up to moderate to strong breeze. Elsewhere across the Atlantic, quiescent conditions prevail with surface ridging along 33N34W west- southwestward to Hispaniola. The cold fronts over the Atlantic have merge today. The front will reach the SE Bahamas by Sat morning. The front is expected to reach far eastern Cuba near 75W by Sat afternoon, then begin to dissipate from 24N65W to the SE Bahamas along 23N75W by Sun afternoon. Swell generated by these fronts will dominate the waters E of the Bahamas through the weekend. A new cold front is forecast to reach the north waters late on Tue and sink southward across the NW half of the area through Wed. Low pressure is expected to develop along the front Tue through Wed near Bermuda and produce strong to near gale force NE winds across the far northern waters.
