INVEST 99L - 40/40

[WxWatcher007]

East of the Windward Islands (AL99):
Showers and thunderstorms have increased and are beginning to show 
signs of organization in association with a tropical wave located 
about 500 miles east of the Windward Islands. This system could 
become a tropical depression during the next day or two while it 
moves quickly westward at about 20 to 25 mph, passing through the 
Windward and Leeward Islands late on Sunday. Regardless of 
development, locally heavy rainfall and gusty winds are possible 
across portions of the Windward and Leeward Islands on Sunday and 
Monday. The system is expected to reach the central Caribbean on 
Tuesday, where conditions are expected to become less favorable for 
additional development. An Air Force reconnaissance aircraft is 
scheduled to investigate the system tomorrow, if necessary.  
* Formation chance through 48 hours...medium...40 percent.
* Formation chance through 7 days...medium...40 percent.
