TROPICAL WEATHER OUTLOOK
NWS NATIONAL HURRICANE CENTER MIAMI FL
200 PM EDT TUE AUG 23 2016

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

The National Hurricane Center has issued the last advisory on Tropical Depression Fiona, located several hundred miles north of the Leeward Islands, and continues to write advisories on Tropical Storm Gaston, located several hundred miles west of the Cabo Verde Islands.

Reports from an Air Force Reserve Hurricane Hunter aircraft indicate that the tropical wave located a few hundred miles east of the Lesser Antilles has an elongated and poorly defined circulation. In addition, satellite imagery indicates that the associated shower and thunderstorm activity remains disorganized. Environmental conditions are only marginally conducive for development during the next couple of days while the system moves west-northwestward at 15 to 20 mph near the northern Leeward Islands and the Greater Antilles. Large- scale conditions could become more conducive later this week while the system moves nears the southeastern and central Bahamas. Another Air Force Reserve Hurricane Hunter aircraft is scheduled to investigate this disturbance tomorrow, if necessary. Interests from the islands of the northeastern Caribbean Sea to the Bahamas should continue to monitor the progress of this system. Gusty winds, heavy rains, and possible flash floods and mud slides could occur over portions of these areas regardless of tropical cyclone formation. Please consult products issued by your local meteorological offices for further details. * Formation chance through 48 hours...medium...40 percent * Formation chance through 5 days...medium...60 percent

&& Public Advisories on Gaston are issued under WMO header WTNT32 KNHC and under AWIPS header MIATCPAT2. Forecast/Advisories on Gaston are issued under WMO header WTNT22 KNHC and under AWIPS header MIATCMAT2.
