000 AXNT20 KNHC 102250 TWDAT Tropical Weather Discussion NWS National Hurricane Center Miami FL 650 PM EDT Wed Apr 10 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. ...SPECIAL FEATURES... ...Far Eastern Atlantic Gale Warning... Gale force winds out of the north-northeast are expected off the coast of Morocco in the marine zone of Agadir through Thursday, according to the Meteo-France forecast. For more details, refer to the Meteo France High Seas Forecast listed on their website: www.meteofrance.com/previsions-meteo- marine/bulletin/grandlarge/metarea2. ...MONSOON TROUGH/ITCZ... The monsoon trough extends from the coast of Liberia near 04N08W to 02N17W. The ITCZ continues from 02N17W to 04N30W to the coast of Brazil near 00N48W. Scattered moderate convection is noted 100 nm to the north of the ITCZ from 00N-03S between 28W-30W and 180 nm to the south of the ITCZ from 03S-08S between 18W-28W. Elsewhere along both boundaries, scattered showers are present. GULF OF MEXICO... A slow moving dissipating frontal boundary extends off the southwest coast of Florida near 25N81W to the Caribbean. Some showers associated with the front and digging mid-level trough are exiting the Gulf with a 1013 mb high pressure taking control of the area. Benign conditions prevail across the rest of the basin as a 1013 mb high is right off the northwest Yucatan near 24N88W. Winds are generally light to gentle out of the north- northwest. High pressure is centered over the south central Gulf in the wake of a cold front that moved through the region this morning. Expect fresh to strong southerly winds over the western Gulf through Thu between the high pressure and a trough over the southern Plains. These winds will diminish through Fri as the high pressure shifts east, but increase again Sat ahead of another front expected to move off the Texas coast late Sat into early Sun. Fresh to strong northerly winds and building seas will follow the front Sun, reaching near gale force off Veracruz late Sun. Winds and seas will diminish across the Gulf Mon as the front stalls and weakens from the Florida Keys to the northwest Yucatan. CARIBBEAN SEA... A slow moving dissipating frontal boundary extending across the southeast Gulf of Mexico stretches across the northwest Caribbean to just off the coast of Belize. Ahead of the front, numerous showers with embedded thunderstorms are seen moving across central Cuba and the west-central Caribbean and beginning to approach Jamaica. A pre-frontal trough is also seen ahead of the front from 22N81W to 17N84W. To the east, low-topped showers are quickly moving across the Lesser Antilles, Puerto Rico, and the Dominican Republic. Gentle to moderate trades are seen across most of the Caribbean, with light trades in the southwest portion of the basin. Ahead of the incoming front, winds are gentle out the south-southeast. Behind the front, winds are mostly gentle out of the northwest. A weakening cold front from western Cuba to central Honduras will dissipate through tonight. A weak ridge to the north will promote only moderate to fresh breeze tradewinds across the Caribbean through Fri. As the ridge strengthens and increases the pressure gradient, winds - especially north of Colombia and north of Honduras - will be enhanced on Sat through early next week. ATLANTIC OCEAN... Refer to the section above for details on the Gale Warning in effect for the far east Atlantic waters. A dissipating front continues to push east off the Florida coast. A 1008 mb low located near 32N77W has a cold front extending southwest across the Florida Peninsula into the western Caribbean. Mix of low and mid level clouds are spread across the western Atlantic into the Bahamas and western Cuba along a trough 100 nm ahead of the front. Scattered to numerous showers and embedded thunderstorms are moving north off of Cuba into the Bahamas ahead of the front from 22N-31N between 71W-79W. Surface riding prevails across the remainder of the basin with a 1023 mb high located near 27N32W. A weaken cold front from 1008 mb low pressure near 32N77W to southeast Florida will move east and dissipate tonight. Fresh to strong NE winds will follow second front currently north of the region that will drift south and extend along roughly 29N Fri before dissipating into Sat. A weak trough north of Hispaniola will dissipate through late Sat as it drifts northeast off the Bahamas. S winds will increase off northeast Florida late Sun ahead of another cold front expected to move off the coast early Mon and reach from roughly 31N70W to southeast Florida by Mon night.
