000 AXNT20 KNHC 291025 TWDAT Tropical Weather Discussion NWS National Hurricane Center Miami FL 625 AM EDT Mon Jun 29 2020 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 0600 UTC surface analysis and satellite imagery through 1015 UTC. ...TROPICAL WAVES... A tropical wave is in the E Atlc extending from 01N-13N with axis along 26W, moving westward at 10-15 kt. Scattered moderate convection is noted in the wave environment mainly south of 08N. A tropical wave is in the central Atlc extending from 04N-16N with axis along 43W, moving westward around 10 kt. Scattered moderate convection is noted moderate convection is from 05N-15N between 38W-46W. A tropical wave extends its axis from 03N-19N and along 55W, moving westward around 10 kt. Scattered showers are noted near the wave axis and south of 10N. A tropical wave is in the W Caribbean extending S of 17N with axis along 81W, moving westward around 10-15 kt. Scattered moderate convection is S of 16N between 77W-83W. ...MONSOON TROUGH/ITCZ... The monsoon trough extends from the W coast of Africa near 12N16W to 08N22W. The ITCZ extends from 08N22W to 06N25W, then resumes west of a tropical wave from near 06N27W to 08N42W. The ITCZ resumes once again west of another tropical wave from 08N44W to 05N52W. Besides the convection mentioned in the tropical wave section above, scattered moderate convection prevails along the ITCZ. GULF OF MEXICO... A 1018 mb high centered over the W Atlantic near 26N73W extends a ridge axis towards SE Louisiana. Scattered showers are along the coast of S Louisiana and over the E Gulf of Mexico N of 23N. High pressure will remain centered over the eastern Gulf into late week. This will continue supporting moderate to fresh SE winds over the western Gulf, and light to gentle winds over the eastern Gulf. CARIBBEAN SEA... Refer to the section above for details on the tropical wave moving across the basin, and the next one approaching the Lesser Antilles. A high pressure ridge extends just north of the Bahamas. The resulting pressure gradient is causing moderate to fresh E trades across the basin, with strongest winds prevailing just north of Colombia. Most of the Caribbean is covered by a moderate Saharan Air Layer/African Dust event, though visibilities are only slightly inhibited. Scattered moderate convection prevails in the SW Caribbean and Central America in connection with a tropical wave and the NE Pacific monsoon trough. High pressure prevails north of the area supporting fresh to strong trades across the south central Caribbean into the end of the week. Pulses of fresh winds are also possible in the Gulf of Honduras over the next few nights. A tropical wave is currently moving across the west Caribbean with convection, while the next one will approach the Leeward Islands by mid-week. ATLANTIC OCEAN... Refer to the section above for details on the tropical waves moving across the area. A 1018 mb high is centered E of the Bahamas near 26N73W. A 1031 mb high is centered SW of the Azores near 37N35W. Some of the Saharan Air Layer/African dust outbreak from earlier days still remain north of 25N west of 70W. A new Saharan Air Layer/African dust region extends from around 07N-25N between West African and 54W behind a tropical wave. High pressure will dominate the area, bringing gentle to moderate winds into mid-week. A tropical wave will approach Atlantic waters north of the Lesser Antilles Tue. $$ ERA
