200 AM EDT TUE AUG 23 2016
For the North Atlantic...Caribbean Sea and the Gulf of Mexico:
The National Hurricane Center is issuing advisories on Tropical
Depression Fiona, located several hundred miles north-northeast of
the Leeward Islands, and on recently upgraded Tropical Storm Gaston,
located about 450 miles west-southwest of the Cabo Verde Islands.
1. A tropical wave located about 400 miles east-southeast of the
Leeward Islands is producing widespread cloudiness and
thunderstorms. Conditions are marginally conducive for gradual
development while the disturbance moves west-northwestward to
westward at 15 to 20 mph. Environmental conditions are expected to
become more conducive for a tropical depression to form by late this
week when the system is forecast to move near Hispaniola and Puerto
Rico, and the southeastern and central Bahamas. An Air Force Reserve
Hurricane Hunter aircraft is scheduled to investigate this system
later this morning. Interests in the central and northern Lesser
Antilles, the Virgin Islands, and Puerto Rico should monitor the
progress of this system.
* Formation chance through 48 hours...medium...60 percent
