Tropical Weather Outlook
NWS National Hurricane Center Miami FL
200 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
Storm Nana, inland near the Guatemala-Mexico border, and on
Tropical Depression Omar, located a few hundred miles northeast of
Bermuda.
1. 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 as
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.
2. 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 likely 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.
3. 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, and some development of this low will be
possible early next week 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...low...20 percent.
