TROPICAL WEATHER OUTLOOK
NWS NATIONAL HURRICANE CENTER MIAMI FL
800 PM EDT SAT AUG 20 2016

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

The National Hurricane Center is issuing advisories on Tropical
Storm Fiona, located about 875 miles east-northeast of the Leeward
Islands.

A broad area of low pressure, associated with a tropical wave, is
located about midway between the west coast of Africa and the Lesser
Antilles.  The associated shower activity remains disorganized, and
any development of this system during the next couple of days should
be slow to occur due to its large size and proximity to dry air.
Environmental conditions are forecast to be more conducive for
development beyond a couple of days, and a tropical depression could
form by the middle of next week while the system moves westward and
then west-northwestward at 15 to 20 mph across the tropical Atlantic
Ocean, through the eastern Caribbean Sea, and then near the Greater
Antilles.
* Formation chance through 48 hours...low...10 percent
* Formation chance through 5 days...medium...60 percent

A weak area of low pressure, associated with another tropical wave,
is moving off the coast of Senegal in western Africa while producing
a large area of cloudiness and thunderstorms.  Environmental
conditions appear conducive for gradual development, and a tropical
depression is likely to form in a few days while the system moves
westward and then northwestward over the eastern tropical Atlantic
Ocean.
* Formation chance through 48 hours...low...30 percent
* Formation chance through 5 days...high...70 percent
