A tropical wave located over the central tropical Atlantic continues 
to produce a broad area of disorganized showers and thunderstorms. 
Environmental conditions appear conducive for gradual development of

week or over the weekend while it moves near or the north of the 
northern Leeward Islands.
* Formation chance through 48 hours...low...10 percent.
* Formation chance through 7 days...medium...60 percent.

2. Eastern Tropical Atlantic (AL99):
Recent satellite-derived wind data indicate that a concentrated 
area of showers and thunderstorms located just southwest of the Cabo 
Verde Islands lacks a closed surface circulation.  Environmental 
conditions appear marginally favorable for additional development 
over the next day or so while the system moves westward at around 15 
mph.  By the end of the week, environmental conditions are expected 
to become unfavorable for further development.
