Narrative:

We departed hpn runway 16 on the westchester 4 SID. As we reached 800 ft and initiated the turn to 320 we got a TA. ATC amended our instructions and were given runway heading maintain 2;000 ft. We both visually acquired the traffic and it continued to turn and climb into our flight path prompting an RA of 'monitor vertical speed.' the first officer informed the tower of the RA as traffic passed beneath us with the TCAS displaying 200 ft on the target. We were then issued a climb to 3;000 ft and the turn to 320. We were given a number to call back in hpn. Upon arrival I notified the assistant chief pilot (acp) of our incident and then called hpn tower. The controller I spoke with explained that the traffic was a VFR departure off of runway 11 before we departed 16. He further explained that the traffic was supposed depart straight out or make a left turn out from that runway.
