000 AXNT20 KNHC 290505 TWDAT Tropical Weather Discussion NWS National Hurricane Center Miami FL 105 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 0000 UTC surface analysis and satellite imagery through 0500 UTC. ...TROPICAL WAVES... A tropical wave is in the E Atlc extending from 01N to 13N with axis along 25W, moving westward at 10-15 kt. Scattered moderate convection is from 04N-08N between 20W-30W. A tropical wave is in the central Atlc extending from 03N to 16N with axis along 40W/41W, moving westward around 10 kt. Isolated moderate convection is from 05N-15N between 36W-47W. A tropical wave extends from 06N to 19N with axis along 54W, moving westward around 10 kt. Isolated moderate convection is from 04N-13N between 47W-57W. A tropical wave is in the W Caribbean extending S of 18N with axis along 79W, moving westward around 10 kt. Scattered moderate convection is S of 16N between 70W-90W ...MONSOON TROUGH/ITCZ... The monsoon trough extends from the W coast of Africa near 11N16W to 08N21W. The ITCZ extends from 08N21W to 08N40W, then resumes west of a tropical wave from near 08N43W to 05N53W. Besides the convection mentioned in the tropical wave section, scattered moderate convection is from 03N-08N between 30W-37W. GULF OF MEXICO... A 1018 mb high centered over the W Atlantic near 27N75W 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 bring moderate to fresh SE winds over the western Gulf with 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 moderate high pressure ridge extends west-northwest to east- southeast just north of the Bahamas. The resulting pressure gradient is causing generally moderate to fresh E trades, except for strong E trades 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. Aside from the convection in the SW Caribbean in connection with a tropical wave and the NE Pacific monsoon trough, scattered showers are observed over Cuba, Hispaniola, Puerto Rico, and the Leeward Islands. Fresh to strong trades will prevail across the south-central Caribbean into late week. Pulses of fresh to locally strong winds are also possible in the Gulf of Honduras over the next few nights. A tropical wave will the Leeward and Windward Islands Tue. 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 27N75W. Scattered showers are over the N Bahamas. and the W Atlantic W of 65W. A 1031 mb high is centered SW of the Azores near 36N35W. Some of the big Saharan Air Layer/African dust outbreak from earlier days still remain north of 25N west of 70W, though this is weakening. 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. $$ Formosa
