Tropical Weather Outlook
NWS National Hurricane Center Miami FL
800 AM EDT Mon Aug 17 2020

For the North Atlantic...Caribbean Sea and the Gulf of Mexico:

1. A fast-moving tropical wave located a couple of hundred 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 today through Tuesday morning.
* Formation chance through 48 hours...low...20 percent.
* Formation chance through 5 days...medium...50 percent.

2. Another tropical wave located over the eastern tropical Atlantic 
to the south-southwest of the Cabo Verde Islands is producing 
disorganized cloudiness and 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 and western portions of the tropical Atlantic.
* Formation chance through 48 hours...low...20 percent.
* Formation chance through 5 days...medium...60 percent.
