000 ABNT20 KNHC 180511 TWOAT Tropical Weather Outlook NWS National Hurricane Center Miami FL 200 AM EDT Tue Aug 18 2020 For the North Atlantic...Caribbean Sea and the Gulf of Mexico: Disorganized showers and thunderstorms continue in association with a tropical wave located over the eastern Caribbean Sea. This disturbance is moving westward at about 20 mph, and is forecast to continue to move quickly westward over the eastern and central Caribbean Sea during the next couple of days, which is likely to limit significant development. After that time, however, the system is forecast to move more slowly westward across the western Caribbean, where upper-level winds could become more conducive for the development of a tropical depression during the latter part of this week. Regardless of development, locally heavy rainfall and gusty winds are expected over portions of the Windward and southern Leeward Islands this morning. * Formation chance through 48 hours...low...20 percent. * Formation chance through 5 days...medium...60 percent. A broad area of low pressure located a little over 700 miles west-southwest of the Cabo Verde Islands is producing a concentrated area of showers and thunderstorms displaced to the west of an elongated surface circulation. Environmental conditions are conducive for further development, and a tropical depression is likely to form within the next day or two while the system moves westward to west-northwestward at 15 to 20 mph across the central and western portions of the tropical Atlantic. * Formation chance through 48 hours...high...70 percent. * Formation chance through 5 days...high...90 percent. $$ Forecaster Roberts
