000 AXNT20 KNHC 150901 TWDAT Tropical Weather Discussion NWS National Hurricane Center Miami FL 0605 UTC Fri Apr 15 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 0000 UTC surface analysis and satellite imagery through 0500 UTC. ...MONSOON TROUGH/ITCZ... The monsoon trough enters the Atlantic Ocean through the coast of Guinea near 10N15W and continues to 04N19W. The ITCZ extends from 04N19W to 01N30W to the coast of Brazil near 02S44W. Scattered moderate convection is noted within 120 nm north of the ITCZ between 25W and 45W. GULF OF MEXICO... A stationary front extends from Pensacola, Florida to South Texas. No significant convection is along this boundary. Gentle to moderate easterly flow dominates most of the basin, except for moderate to fresh winds in the NW basin and within the Florida Straits. Seas are 4 to 6 ft over most of the Gulf, except in the NW Gulf, seas are up to 8 ft. Otherwise, patchy areas of haze are possible over portions of the southwestern and west-central Gulf with some reduction to visibilities, due to ongoing seasonal agricultural fires in portions of Central America and Mexico. For the forecast, the stationary front will start to lift north as a warm front through Fri. Moderate to locally fresh SE return flow will dominate most of the basin late Fri through Sun. A cold front will move into the NW Gulf Mon and stall over the northern Gulf through Tue. CARIBBEAN SEA... Except for the greater Antilles, most of the basin is relatively quiet in terms of precipitation. A 1025 mb high pressure center SE of Bermuda continues to tighten the pressure gradient in the Caribbean, thus resulting in strong winds offshore Honduras, Belize, and NW Colombia. A recent scatterometer pass observed fresh trade winds elsewhere in the central and eastern Caribbean. Mainly moderate E winds are elsewhere west of 80W. Seas are 6 to 9 ft in the south-central Caribbean, 5 to 7 ft elsewhere in the eastern half of the Caribbean, and 3 to 5 ft in the NW Caribbean. Looking ahead, a robust mid-level trough is likely to form this weekend over the southeastern Bahamas and Windward Passage area. Periods of enhanced rainfall and strong thunderstorms are likely over eastern Cuba, Hispaniola, Puerto Rico, and the Turks and Caicos Islands from this weekend through much of next week. For the forecast, the pressure gradient between high pressure located just SE of Bermuda and low pressure over Colombia will continue to support fresh to strong trades over the south-central Caribbean through Fri night. Fresh east to southeast winds will pulse to strong in the Gulf of Honduras at night through Fri. A north to south aligned trough is forecast to develop along 75W from N coast of Colombia across the SE Bahamas Mon through Tue. ATLANTIC OCEAN... A 1025 mb high pressure is centered SE of Bermuda. Broad surface ridging extends SW from the high pressure to central Florida. Gentle to moderate southerly winds are north of 25N and west of 70W, where seas are 4 to 6 ft. Moderate to fresh easterly winds are south of 25N and west of 40W, where seas are 7 to 9 ft. Over the central Atlantic, a cold front continues to drift south extending from 31N38W to 28N47W. Light to gentle winds surround the front, however, seas behind the boundary are 10 to 12 ft. A shearline is south of the cold front, extending along 20N between 35W and 45W with moderate to fresh E winds north of the boundary. Gentle to moderate winds are noted elsewhere in the Atlantic between 20W and 40W, where seas are 7 to 9 ft. Fresh NW winds are noted north of 20N and east of 20W surrounding the Canary Islands. For the forecast west of 55W, the shearline will remain nearly stationary along 20N through Fri. A band of fresh to strong NE to E winds, with seas in the 8 to 9 ft range will persist across the waters S of 23N through the upcoming weekend as a high pressure center remains in the vicinity of Bermuda. A weak cold front will move off the southeastern U.S. coast Fri morning and become stationary there Fri night. A sharp trough is expected to develop from the Windward Passage northward across the SE Bahamas along 75W Mon. Low pressure develops along the trough near 26N75W Mon night, shifts NNE, and exits the region Tue. $$ Mora
