NWS National Hurricane Center Miami FL
800 AM EDT Sun Sep 13 2020

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

The National Hurricane Center is issuing advisories on Hurricane 
Paulette, located over the western Atlantic, Tropical Depression 
Rene, located over the central Atlantic, on Tropical Storm Sally, 
centered over the eastern Gulf of Mexico, and on Tropical Depression 
Twenty, located over the eastern tropical Atlantic. 

1. A surface trough over the west-central Gulf of Mexico is producing 
limited shower activity.  Any development of this system is 
expected to be slow to occur while it moves southwestward and then 
southward at 5 to 10 mph over the western Gulf of Mexico during 
the next few days.
* Formation chance through 48 hours...low...10 percent. 
* Formation chance through 5 days...low...20 percent.

2. An area of low pressure is located a little over a hundred miles 
west of the Cabo Verde Islands.  Although the low's circulation 
appears somewhat elongated, the associated shower and thunderstorm 
activity is showing some signs of organization.  Environmental 
conditions are expected to be conducive for additional development 
during the next day or so while the system moves toward the 
north-northwest at 5 to 10 mph, and a tropical depression is likely 
to form before it moves over colder waters and into an area of 
strong upper-level winds by Tuesday.
* Formation chance through 48 hours...high...70 percent. 
* Formation chance through 5 days...high...70 percent.

3. A tropical wave is forecast to move off the west coast of Africa 
within the next couple of days.  Some gradual development of the 
system will be possible thereafter as the disturbance moves slowly 
westward over the far eastern tropical Atlantic.
* Formation chance through 48 hours...low...near 0 percent. 
* Formation chance through 5 days...low...20 percent.
