Bos controller described a conflict event between two IFR departures from different runways; listed ...

Narrative:

I cleared an A320 for takeoff on runway 4R. Wind was strong out of the northwest. Once airborne; I instructed the A320 to contact the departure controller. Almost immediately; I noticed the A320 was climbing toward a C402 that had departed runway 4L. The C402 was climbing on the 4R extended center line area instead of tracking to the northwest as expected. The C402 had been worked by the local control west (lcw) controller and had been assigned a 350 heading which was inadequate; during strong northwest wind to ensure separation between the two runways. I immediately notified the departure controller of the impending conflict between the two aircraft. I should have talked more with the lcw controller about the wind and the runway 4L departures. I should have also recognized the conflict before I had the A320 change frequencies so that I could have issued instructions to resolve the conflict.
