Narrative:
While on a right downwind for runway 33 at ads; we had a TCAS traffic alert for VFR traffic that was below our aircraft and within 500 ft. The VFR traffic was headed northwest and was not identified to us by the approach controller. We did not receive an RA; but received an aural 'traffic; traffic' and visually acquired the target below us at about 400-500 ft.
