Surface troughs over the Northwest Bahamas and Southeastern islands interact with a mid to upper level low, just north of central Cuba, to support pockets of unsettled weather across the islands.  The mid to upper low will slowly drift southwestward to the northern Caribbean Sea but will still enhance shower activity over the Southeast Bahamas and Turks and Caicos Island through Thursday.  Weak high pressure across the area will maintain light to moderate breezes through the weekend.  A surface trough is expected to develop just east of the Northwest Bahamas on Sunday.
