000 AXNT20 KNHC 061815 TWDAT Tropical Weather Discussion NWS National Hurricane Center Miami FL 215 PM EDT Mon Jul 6 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 1200 UTC surface analysis and satellite imagery through 1715 UTC. ...SPECIAL FEATURES... Tropical Storm Edouard is centered near 40.8.0N 50.0W at 1500 UTC or 378 nm SSE of Cape Race Newfoundland, moving NE at 32 kt. Estimated minimum central pressure is 1007 mb. Maximum sustained wind speed is 40 kt with gusts to 50 kt. Edouard is expected to accelerate across the north central Atlantic during the next couple of days. Little significant change in strength is forecast while Edouard is forecast to become post-tropical this evening. Please read the latest NHC Public Advisory at https://www.nhc.noaa.gov/text/MIATCPAT5.shtml and Forecast Advisory at https://www.nhc.noaa.gov/text/MIATCMAT5.shtml for more details. ...TROPICAL WAVES... An eastern Atlantic tropical wave with an axis along 25W from 00N-19N, is moving west at 15 kt. Saharan dust is noted over much of the eastern Atlantic, mainly from 13N-22N east of 40W. Due to this associated dry air scattered moderate convection is confined near the monsoon trough from 03N-08N between 20W-30W. An eastern Atlantic tropical wave with axis along 52W/53W from 04N-19N is moving west at 15-20 kt. Scattered moderate to isolated strong convection is from 10N-14N between 54W-59W. Isolated moderate convection is elsewhere within 90 nm of the wave axis. A tropical wave in the eastern Caribbean extends along 65W from 06N-22N, moving west at 15 kt. Isolated moderate convection is within 300 nm of the wave axis. ...MONSOON TROUGH/ITCZ... The monsoon trough extends from 19N16W to 12N20W. The ITCZ is analyzed from 12N20W to 08N23W. The ITCZ resumes W of a tropical wave near 07N27W and continues to 06N40W to 10N51W. The ITCZ resumes W of another tropical wave near 10N54W to 09N60W. Besides the convection mentioned in the tropical wave section, widely scattered moderate convection is from 07N-14N between 13W-20W. Scattered moderate convection is from 03N-11N between 30W-47W. GULF OF MEXICO... As of 06/1500 UTC, a 1010 mb low is centered over the Florida Panhandle near 31N85W. Isolated moderate convection is over the NE Gulf of Mexico N of 27N and E of 93W. Similar convection is over all of Florida. A surface ridge axis extends from Tampa Florida to Tampico Mexico. Moderate to fresh winds are noted. Scattered showers are within 180 nm of the northern coast of the Yucatan Peninsula. A narrow high pressure ridge will persist along 25N-26N for the next several days, with moderate to occasionally fresh S to SE winds prevailing over the waters W of 93W. A low pressure trough will move off the Yucatan Peninsula each evening and freshen winds over the SW Gulf. CARIBBEAN SEA... Refer to the section above for details on the tropical wave moving across the eastern Caribbean. A weakening upper trough extends from over the Windward Passage to W Panama. Subsident northerly flow on the west side of this feature has suppressed the convection across the basin. Surface ridging north of the area is maintaining fresh trades over the southern Caribbean, reaching 25 kt off of Colombia. Gentle to moderate trades are noted across the basin. Seas range between 3-6 ft, with seas 7-8 ft north of Colombia. High pressure N of the area will maintain fresh to strong trade winds in the south-central Caribbean through Fri, increasing to near gale force Thu night. Strong winds will pulse at night in the Gulf of Honduras tonight and Fri night. Expect increasing winds, seas and active weather over the Tropical N Atlantic waters today and Tue associated with a tropical wave that will cross the Lesser Antilles on Tue. This wave will affect the eastern basin through Wed. ATLANTIC OCEAN See the Special Features section for information on T.S. Edouard and the tropical waves moving across the basin. Isolated moderate convection is over the W Atlantic W of 75W to include the Bahamas. A surface ridge extends along 26N-27N west of 55W, supporting gentle to moderate winds and seas of 3-5 ft persist over open waters. A weak high pressure ridge along 27N will gradually lift northward this week. Low pressure across the SE U.S. will approach the coast of the Carolinas Wed through Thu and drag a trough across the northern Florida offshore waters. Moderate to fresh southerly winds will affect the northwest and north-central offshore waters N of 27N during this time. Farther east, a surface ridge extends from 1032 mb high pressure near 42N28W to 28N54W, then WSW to the central Bahamas. Fresh to strong trades and 7 to 9 ft seas are noted over much of the eastern Atlantic between this ridge and the deep tropics. The tropical wave along 52W/53W will move across the tropical N Atlantic waters and the Lesser Antilles today through Tue, bringing a modest increase in winds and seas, and very active weather southward of 14N. $$ Formosa
