Atlantic Ocean.

north-northeast of the southeastern Bahamas is producing a large 
area of disorganized showers and thunderstorms.  Environmental 
conditions are forecast to be marginally conducive for gradual 
development during the next few days, and a tropical depression is 
likely to form while the system moves north-northwestward to 
northward across the western Atlantic.
