Tropical Weather Outlook Text


200 AM 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 over the central tropical Atlantic.

1. A broad area of low pressure, associated with a tropical wave, is
located about 700 miles west-southwest of the Cabo Verde Islands.
This disturbance is producing a large but disorganized area of
showers and thunderstorms, and any development of this system during
the next couple of days should be slow to occur due to its proximity
to dry air.  Environmental conditions are forecast to be more
conducive for development after that time, and a tropical depression
could form by the middle of next week while the system moves
westward at 15 to 20 mph across the tropical Atlantic Ocean and into
the eastern Caribbean Sea.
* Formation chance through 48 hours...low...10 percent
* Formation chance through 5 days...medium...50 percent

2. A tropical wave inland over western Africa is producing a large area
of showers and thunderstorms.  This system is expected to move over
water by late Saturday night, and environmental conditions appear
conducive for gradual development next week while it moves generally
west-northwestward over the eastern tropical Atlantic Ocean.
* Formation chance through 48 hours...low...10 percent
* Formation chance through 5 days...medium...40 percent
