 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.
