800 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 of the
Leeward Islands, and on Tropical Storm Gaston, located about 450
miles west of the Cabo Verde Islands.

1. A large area of disorganized showers and thunderstorms located a few
hundred miles east of the Leeward Islands is associated with a
tropical wave.  Environmental conditions are somewhat conducive for
development of this system during the next couple of days while
it moves west-northwestward at 15 to 20 mph near the northern
Leeward Island and the Greater Antilles.  Large-scale conditions
could become more conducive later this week while the system moves
near Hispaniola and then the southeastern and central Bahamas. An
Air Force Reserve Hurricane Hunter aircraft is scheduled to
investigate this disturbance later this morning. Interests from the
islands of the northeastern Caribbean Sea to the Bahamas should
monitor the progress of this system.  Gusty winds, heavy rains, and
possible flash floods and mud slides could occur over these areas
regardless of tropical cyclone formation. Please consult products
issued by your local meteorological offices for further details.
