000 AXNT20 KNHC 090006 TWDAT Tropical Weather Discussion NWS National Hurricane Center Miami FL 805 PM EDT Sat Jun 8 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 2315 UTC. ...TROPICAL WAVES... A tropical wave is partially over Africa along 12W from 01N-12N, moving W at 15 kt. The wave shows up well in the satellite imagery and in the model diagnostic data. Widely scattered moderate convection is from 03N- 06N between 11W-15W. An Atlantic tropical wave is along 32W from 01N-15N, moving W at 20 kt. Widely scattered moderate convection is from 03N-08N between 29W-36W. An Atlantic Ocean tropical wave is along 48W from 01N-14N, moving W at 15-20 kt. Isolated moderate convection is from 02N-14N between 45W-51W. A Caribbean Sea tropical wave is along 68W from 02N-15N, moving W at 15 kt. Scattered moderate convection is from 05N-13N between 62W-70W. ...MONSOON TROUGH/ITCZ... The monsoon trough passes through the coastal sections of Guinea- Bissau near 12N15W to 08N18W to 06N22W. The ITCZ extends from 06N22W to 06N31W, then resumes W of a tropical wave near 05N34W to 05N46W. Besides the convection mentioned in the tropical wave section, scattered moderate convection is from 03N-07N between 36W- 44W. GULF OF MEXICO... As of 08/2100 UTC, a cold front extends from S Mississippi near 30N88W to the NW Gulf near 27N92W to S Texas near 27N97W. Scattered showers are within 60 nm of the front N of 27N. Scattered moderate convection is in the warm section over the NE Gulf from 28N-31N between 83W-87W. Elsewhere, scattered moderate convection is over central and south Florida S of 29N. A broad low pressure area over the southern U.S. will maintain moderate southwest to west winds across the NE and north-central Gulf through Sun. A weak cold front in the NW Gulf will stall and weaken in the north central Gulf overnight. A stronger cold front will move across the NW Gulf Mon, then weaken in the northern Gulf Tue and Wed. CARIBBEAN SEA... 10-20 kt tradewinds are over the Caribbean Sea with strongest winds over the south central Caribbean, and weakest winds over the far SW Caribbean. Besides the convection associated with the tropical wave, widely scattered moderate convection is over Puerto Rico, E Hispaniola, and Cuba. Clusters of scattered moderate to isolated strong convection is inland from Honduras to Panama. A weak ridge north of the area will support moderate to locally fresh trade winds across most of the Caribbean Sea during the next several days. Fresh to strong trade winds are expected in the south central Caribbean Sea through Thu, with building seas to 9 ft. ATLANTIC OCEAN... Widely scattered moderate convection is over the W Atlantic N of 25N and W of 75W. A large 1032 mb high is centered over the central Atlantic near 37N38W. Of note in the upper levels, an upper level low is centered over the W Atlantic near 25N64W. Scattered showers are within 300 nm of the center. A ridge will dominate most of the W Atlantic through Mon while a low pressure area will remain over the SE of United States. Moderate southerly winds are expected across the Atlantic the next few days. A weak cold front will reach the waters off NE Florida by late Tue, then lift N of the area by Wed.
