 Hurricane Arlene originated out of an area of low pressure associated with a decaying frontal system along the North Carolina coastline on August 8 . Tracking towards the southeast in a gradual anticyclonic loop , the system slowly increased in organization and intensity . By August 10 , the low neared the Bahamas but remained disorganized . The following day , while located over Andros Island , the National Hurricane Center ( NHC ) upgraded the system to a tropical depression , the third of the season , based on its appearance on satellite imagery .
