Atlantic Ocean about 350 miles south of the Azores.  Shower and

southeastern Florida, the central Bahamas, and the Straits of 
Florida is associated with a frontal system. This disturbance is 
forecast to continue moving southward over central and western Cuba

Thursday through Saturday. Upper-level winds are expected to become 
marginally conducive for development by Thursday and Friday when the 
system is forecast to approach the Florida Keys and South Florida.  
Regardless of development, locally heavy rainfall can be expected
