800 PM EDT Sun Sep 6 2020

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

1. Thunderstorm activity associated with a well-defined low pressure 
system located about midway between the west coast of Africa and the 
northern Leeward Islands continues to get better organized. A 
tropical depression is expected to form later tonight or on Monday 
while the low moves westward or west-northwestward across the 
central tropical Atlantic.
* Formation chance through 48 hours...high...near 100 percent. 
* Formation chance through 5 days...high...near 100 percent.

2. Showers and thunderstorms continue to steadily increase and are 
showing signs of organization in association with a low pressure 
system located just west of Senegal. Environmental conditions 
are conducive for development, and a tropical depression is 
expected to form within the next day or so while the system moves 
generally westward over the far eastern tropical Atlantic. Interests 
in the Cabo Verde Islands should monitor the progress of this system 
as gusty winds and locally heavy rainfall are likely there Monday 
night and Tuesday. A Tropical Storm Watch or Warning could be 
required for the islands by early Monday.
* Formation chance through 48 hours...high...90 percent. 
* Formation chance through 5 days...high...90 percent.

3. A tropical wave located over the central Caribbean Sea south of 
Jamaica and extending northward across the island is producing 
limited shower and thunderstorm activity.  Upper-level winds are 
forecast to remain unfavorable for development for the next several 
days while the system moves westward, and tropical cyclone formation 
is not expected.
* Formation chance through 48 hours...low...near 0 percent. 
* Formation chance through 5 days...low...near 0 percent.

4. A trough of low pressure located just to the southeast of Bermuda 
is producing disorganized cloudiness and showers.  Some slow 
development of this system is possible during the next several days 
while it moves west-northwestward.
* Formation chance through 48 hours...low...10 percent. 
* Formation chance through 5 days...low...30 percent.

5. A new tropical wave is forecast to emerge off the west coast of 
Africa by the middle to latter part of this week. Some gradual
development will be possible thereafter while the system moves 
generally westward.
* Formation chance through 48 hours...low...near 0 percent. 
* Formation chance through 5 days...low...20 percent.
