Narrative:

ATC assigned heading 215 degrees on departure which is also the runway's heading. At approximately 600 ft AGL TCASII gave a preventive RA of 2500 ft climb. The aircraft was already performing to this climb and was maintained while a search was started to find traffic visually. No traffic was observed and advised ATC of the RA and he responded we were clear of traffic. The target appeared on the TCASII as 300 ft below and 1/2 mi to the aircraft left slightly ahead. No further advisories.
