000 AXNT20 KNHC 081728 TWDAT Tropical Weather Discussion NWS National Hurricane Center Miami FL 205 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 1200 UTC surface analysis and satellite imagery through 1710 UTC. ...TROPICAL WAVES... A tropical wave is in Africa, along 08W/09W from 12N southward. The wave shows up well in the satellite imagery and in the model diagnostic data. Widely scattered moderate to isolated strong rainshowers are from 03N to 07N between 10W and 13W. Much of the cloudiness that is associated with this wave still is in Africa. An Atlantic Ocean tropical wave is along 21W/22W from 15N southward. The wave shows up in long-loop satellite imagery. Isolated moderate to locally strong rainshowers are from 03N to 08N between 17W and 23W. An Atlantic tropical wave is along 30W/31W from 15N southward. Widely scattered to scattered moderate and isolated strong rainshowers cover the area from 03N to 07N between 25W and 35W. Some of the precipitation that is in the same area is related to the ITCZ also. An Atlantic Ocean tropical wave is along 46W from 14N southward. Isolated moderate rainshowers cover the area that is from 06N to 10N between 45W and 50W. Other nearby precipitation is related to the ITCZ also. A Caribbean Sea tropical wave is along 63W/64W from 16N southward. Upper level SW wind flow spans the Caribbean Sea from 70W eastward. Rainshowers are possible within 60 nm on either side of the tropical wave. A Caribbean Sea tropical wave is along 88W/89W from 17N in Belize southward. No significant deep convective precipitation is related directly to the wave. ...MONSOON TROUGH/ITCZ... The monsoon trough passes through the coastal sections of Guinea near 10N15W to 08N19W. The ITCZ extends from 06N23W to 06N30W, to 06N32W to 05N44W. Widely scattered moderate to isolated strong rainshowers, in general, away from the tropical waves, are from 10N southward from 51W eastward, and from 10N southward between 52W and 60W. GULF OF MEXICO... A cold front is in the NW corner of the Gulf of Mexico. It passes through south central Louisiana, to the middle Texas Gulf coast. Widely scattered to scattered moderate and isolated strong rainshowers are in the NE corner of the Gulf of Mexico, from 28N between Louisiana and Florida. Isolated moderate rainshowers have spread across Florida, and into the Atlantic Ocean, from 24N northward from 70W westward. A broad low pressure area in the southern U.S. will maintain moderate southwest to west winds across the NE and north-central Gulf of Mexico through Sunday. A weak cold front in the NW Gulf of Mexico will stall and weaken in the north central Gulf overnight. A stronger cold front will move across the NW Gulf of Mexico on Monday, then weaken in the northern Gulf on Tuesday and Wednesday. CARIBBEAN SEA... An upper level trough reaches Puerto Rico, from a 25N65W Atlantic Ocean cyclonic circulation center. The trough eventually reaches La Peninsula de la Guajira of NE Colombia and parts of NW Venezuela. Scattered moderate to strong rainshowers are within a 30 nm radius of 16N64W. Rainshowers are possible elsewhere to the south of the line that runs from 20N61W to 17N65W to 13N77W to 14N82W. 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 Wednesday night, with building seas. ATLANTIC OCEAN... An upper level trough extends from a 30N40W upper level cyclonic circulation center, to a second cyclonic circulation center that is near 25N65W. The trough continues southwestward to Puerto Rico. Isolated moderate rainshowers cover the area that is from 20N northward between 30W and 50W. Widely scattered moderate to isolated strong rainshowers are from 20N to 27N between 62W and 73W. Isolated moderate rainshowers are elsewhere from 20N northward between 50W and 73W. A 1032 mb high pressure center is near 37N39W. Broad surface anticyclonic wind flow covers the Atlantic Ocean from 18N northward from 70W eastward. A ridge will remain in the southern part of the area through Wednesday. Low pressure is forecast to remain in the southeastern U.S. for this weekend. Moderate southerly winds are expected across the area during the next few days.
