NWS National Hurricane Center Miami FL
800 PM EDT Thu Sep 3 2020

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

The National Hurricane Center is issuing advisories on Tropical 
Depression Nana, inland near the Guatemala-Mexico border, and on 
Tropical Depression Omar, located about 400 hundred miles northeast 
of Bermuda.

1. Shower activity has increased today in association with a 
non-tropical area of low pressure located over the north-central 
Atlantic, about 625 miles south of Cape Race Newfoundland. Some 
slight subtropical or tropical development of this system is 
possible before it reaches cooler waters later on Friday.
* Formation chance through 48 hours...low...20 percent. 
* Formation chance through 5 days...low...20 percent.

2. A broad area of low pressure located over the eastern tropical 
Atlantic several hundred miles west-southwest of the Cabo Verde 
Islands is producing a small area of disorganized showers and 
thunderstorms.  Gradual development is possible early next week once 
the larger tropical wave located off of the coast of Africa passes 
to the north of the system on Sunday.
* Formation chance through 48 hours...low...20 percent. 
* Formation chance through 5 days...medium...40 percent.

3. A tropical wave located off the coast of west Africa is merging with 
another disturbance located a couple of hundred miles south of the 
Cabo Verde Islands, resulting in an extensive area of disorganized 
showers and thunderstorms.  Development of this system is expected 
to be slow during the next couple of days while it moves west- 
northwestward at about 15 mph.  After that, a tropical depression is 
more likely to form early next week over the central tropical 
Atlantic where environmental conditions are forecast to be more 
favorable for development.
* Formation chance through 48 hours...low...20 percent. 
* Formation chance through 5 days...high...70 percent.

4. Another tropical wave is forecast to move off the west coast of 
Africa over the weekend.  An area of low pressure is expected to 
form from the wave early next week. Gradual development of this low 
is then expected, and a tropical depression could form while it 
moves generally westward over the far eastern tropical Atlantic. 
* Formation chance through 48 hours...low...near 0 percent. 
* Formation chance through 5 days...medium...40 percent.
