Narrative:
On arrival to sea, runways changed so crossing altitude on STAR was lowered significantly. Maximum rate descent was initiated while new runway charts were briefed. We made the altitude crossing ok, but failed to make turn for vectors as required by STAR. The high workload combined with runway change, along with avoidance of precipitation on arrival, contributed to approximately 1-2 mi deviation on arrival. There may not be an actual deviation since ATC gave us present heading after the fix where we were supposed to turn. Furthermore, we were in the process of avoiding precipitation when ATC called to give us vectors.

Title: TRACK DEV ON AN ARR TO SEA, WA, WHEN THE FLC IS DISTRACTED WITH WX AND A LATE CLRNC CHANGE.
Narrative: ON ARR TO SEA, RWYS CHANGED SO XING ALT ON STAR WAS LOWERED SIGNIFICANTLY. MAX RATE DSCNT WAS INITIATED WHILE NEW RWY CHARTS WERE BRIEFED. WE MADE THE ALT XING OK, BUT FAILED TO MAKE TURN FOR VECTORS AS REQUIRED BY STAR. THE HIGH WORKLOAD COMBINED WITH RWY CHANGE, ALONG WITH AVOIDANCE OF PRECIPITATION ON ARR, CONTRIBUTED TO APPROX 1-2 MI DEV ON ARR. THERE MAY NOT BE AN ACTUAL DEV SINCE ATC GAVE US PRESENT HEADING AFTER THE FIX WHERE WE WERE SUPPOSED TO TURN. FURTHERMORE, WE WERE IN THE PROCESS OF AVOIDING PRECIPITATION WHEN ATC CALLED TO GIVE US VECTORS.
