Narrative:
Proceeding south on A315 to zin (great inagua) I was on a heading of 120 degrees, climbing to cruise altitude. There were thunderstorms in the area and I had advised ATC I would need to deviate from A315 to avoid some circuit breaker's. I was cleared to deviate as necessary. My attention was outside the cockpit and I missed an ATC clearance to turn to a heading of 100 degrees 'for traffic.' there may have been a loss of sep with another aircraft. My first officer indicated he had heard the clearance but did not bring it to my attention.

Title: ACR LGT DEVIATING AROUND TSTM ACTIVITY FAILED TO TURN AS CLEARED CAUSING POSSIBLE LESS THAN STANDARD SEPARATION.
Narrative: PROCEEDING S ON A315 TO ZIN (GREAT INAGUA) I WAS ON A HDG OF 120 DEGS, CLBING TO CRUISE ALT. THERE WERE TSTMS IN THE AREA AND I HAD ADVISED ATC I WOULD NEED TO DEVIATE FROM A315 TO AVOID SOME CB'S. I WAS CLRED TO DEVIATE AS NECESSARY. MY ATTN WAS OUTSIDE THE COCKPIT AND I MISSED AN ATC CLRNC TO TURN TO A HDG OF 100 DEGS 'FOR TFC.' THERE MAY HAVE BEEN A LOSS OF SEP WITH ANOTHER ACFT. MY F/O INDICATED HE HAD HEARD THE CLRNC BUT DID NOT BRING IT TO MY ATTN.
