000 ABNT20 KNHC 122338 TWOAT Tropical Weather Outlook NWS National Hurricane Center Miami FL 800 PM EDT Sat Sep 12 2020 For the North Atlantic...Caribbean Sea and the Gulf of Mexico: The National Hurricane Center is issuing advisories on Tropical Storm Paulette and Tropical Depression Rene, both located over the central Atlantic Ocean, on Tropical Storm Sally, centered over the southeastern Gulf of Mexico, and on newly formed Tropical Depression Twenty, located over the eastern Tropical Atlantic. A surface trough over the north-central Gulf of Mexico is producing limited shower activity. While some slow development of this system is possible, strong upper-level winds related to Tropical Storm Sally will probably limit the chances of tropical cyclone formation. The disturbance is forecast to move westward and then southwestward over the northern and western Gulf of Mexico through the next few days. * Formation chance through 48 hours...low...10 percent. * Formation chance through 5 days...low...20 percent. Showers and thunderstorms located near and west of the Cabo Verde Islands are associated with a broad area of low pressure. Environmental conditions support some additional development, and a tropical depression could form over the far eastern tropical Atlantic during the next two or three days while the system moves slowly west-northwestward. By mid-week, upper-level winds should become less conducive for development. * Formation chance through 48 hours...medium...50 percent. * Formation chance through 5 days...medium...60 percent. && Public Advisories on Tropical Depression Twenty are issued under WMO header WTNT35 KNHC and under AWIPS header MIATCPAT5. Forecast/Advisories on Tropical Depression Twenty are issued under WMO header WTNT25 KNHC and under AWIPS header MIATCMAT5. $$ Forecaster Blake
