000 AXNT20 KNHC 240602 TWDAT Tropical Weather Discussion NWS National Hurricane Center Miami FL 205 AM EDT Wed Jun 24 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 0510 UTC. ...SPECIAL FEATURES... The center of Tropical Storm Dolly, at 24/0300 UTC, is near 40.1N 61.1W. Dolly is moving ENE, or 60 degrees, 09 knots. The estimated minimum central pressure is 1004 mb. The maximum sustained wind speeds are 35 knots with gusts to 45 knots. Please read the latest NHC Public Advisory at https://www.nhc.noaa.gov/text/MIATCPAT4.shtml and Forecast/ Advisory at https://www.nhc.noaa.gov/text/MIATCMAT4.shtml for more details. ...TROPICAL WAVES... An Atlantic Ocean tropical wave is along 22W/23W from 17N southward, moving westward 10 to 15 knots. Precipitation: the wave is moving through the area of nearby ITCZ precipitation. An Atlantic Ocean tropical wave is along 45W/46W from 18N southward, moving westward 15 to 20 knots. Precipitation: Scattered moderate to strong is from 07N to 11N between 43W and 49W. An Atlantic Ocean tropical wave is along 55W/56W, from 13N southward, moving westward 15 to 20 knots. Precipitation: widely scattered moderate to isolated strong is in parts of Brazil, Suriname, and French Guiana from 05N southward between 53W and 59W. A Caribbean Sea tropical wave is along 84W from 18N southward, moving westward 20 to 25 knots. Warm and stable air, that is associated with a dense plume of Saharan dust, is limiting significant precipitation with this wave. Precipitation: Isolated moderate to locally strong is in the northeastern one-third of Nicaragua. A tropical wave is in the SW corner of the Gulf of Mexico, along 92W/93W from 21N southward, moving westward 10 to 15 knots. Precipitation: isolated moderate to locally strong is from 21N southward from the Yucatan Peninsula westward. ...MONSOON TROUGH/ITCZ... The monsoon trough passes through the coastal border sections of Senegal and The Gambia, to 10N21W 07N28W and 08N34W. The ITCZ extends from 08N34W to 07N43W and 07N55W. Precipitation: widely scattered to scattered moderate and isolated strong is from 03N to 09N between 23W and 32W. Scattered moderate to widely scattered strong is from the ITCZ southward between 50W and 54W. Isolated moderate is elsewhere from 10N southward from 60W eastward. GULF OF MEXICO... An upper level shortwave trough is in the NW Gulf of Mexico. Precipitation: isolated to widely scattered moderate is in the NW corner of the Gulf of Mexico, from 25N northward from 89W westward. A tropical wave is in the SW corner of the Gulf of Mexico, along 92W/93W from 21N southward, moving westward 10 to 15 knots. Precipitation: isolated moderate to locally strong is from 21N southward from the Yucatan Peninsula westward. A surface ridge will prevail in the Gulf of Mexico through the forecast period. Moderate to fresh southerly winds are forecast in the western Gulf of Mexico through Thursday night, due to the pressure gradient between the ridge and lower pressure in Mexico. CARIBBEAN SEA... The monsoon trough is along 08N/09N, from 74W in Colombia beyond Costa Rica. Precipitation: broken to overcast multilayered debris clouds, from earlier dissipating/weakening precipitation, and residual isolated moderate to locally strong, covers the Caribbean Sea from 13N southward from 76W westward. GOES-16 satellite imagery has been showing that dense Saharan dust has been covering most of the Caribbean Sea. The dry and stable air mass that accompanies the dust is helping to bring hazy conditions to the area, and it is helping to suppress precipitation in the Caribbean Sea. Fresh to strong trade winds will prevail across the south central Caribbean Sea through the middle of the week. The area of fresh to strong trade winds will expand to the north central and the southwestern corner of the basin, through the end of the week, as high pressure builds in the western Atlantic Ocean. The Winds will pulse to near gale-force off the coast of Colombia each night, through Sunday night. The sea heights will be building to 12 feet and higher during the times of the fastest wind speeds. Fresh to strong winds are expected to continue in the Gulf of Honduras through Saturday night. ATLANTIC OCEAN... A surface trough is off the coast of the SE U.S.A., along 32N78W to 30N80W. Isolated moderate to locally strong is within 30 nm on either side of the line that runs from 31N77W to 29N79W, to 27N81W at the NW edge of Lake Okeechobee, to 25N81W. A surface trough is along in the north central Atlantic Ocean along 33N53W 26N54W 20N56W. Precipitation: isolated moderate is from 20N northward between 50W and 60W. High pressure extends from the central Atlantic Ocean to Florida, and it will prevail across the offshore waters through the forecast period. Fresh to occasionally strong easterly winds will pulse across the waters that are to the north of Hispaniola on each night, through Sunday night. $$ mt
