000 ABNT20 KNHC 170546 TWOAT Tropical Weather Outlook NWS National Hurricane Center Miami FL 200 AM EDT Mon Aug 17 2020 For the North Atlantic...Caribbean Sea and the Gulf of Mexico: A fast-moving tropical wave located about 400 miles east of the Windward Islands continues to produce disorganized shower and thunderstorm activity. This disturbance is expected to move westward at about 20 mph during the next few days, and that fast forward speed is likely to limit significant development while the system approaches the Windward and southern Leeward Islands today, and moves across the eastern and central Caribbean Sea on Tuesday and Wednesday. After that time, however, the system is expected to move more slowly westward across the western Caribbean Sea, 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 beginning this evening through Tuesday morning. * Formation chance through 48 hours...low...20 percent. * Formation chance through 5 days...medium...50 percent. Another tropical wave located over the far eastern tropical Atlantic well to the south-southeast of the Cabo Verde Islands is producing a large area of cloudiness and disorganized showers. The wave is forecast to move westward to west-northwestward at 15 to 20 mph during the next few days, and environmental conditions are expected to become more conducive for the development of a tropical depression during the middle-to-latter part of this week while the system moves across the central tropical Atlantic. * Formation chance through 48 hours...low...10 percent. * Formation chance through 5 days...medium...60 percent. $$ Forecaster Berg
