Narrative:
Approach control cleared us for the visual on runway 24R, to follow aircraft in sight. On turning base, approach reclred us for runway 24L. Turning onto final, overshot and received a TA/RA from TCASII and communication from tower of the traffic. Turned back to final approach course, and no further incident. Wind at 2500 ft was 310 degrees at 50 KTS. Our outbound heading from smo was 60 degrees to parallel runway. With this wind component, a turn to final required an aggressive turn and a large correction heading. With switching to tower, ILS frequencys and configuring, we overshot final. Vectors to final with strong santa ana wind at low levels, instead of visuals cleared on downwind, is a possible solution.

Title: SANTA ANA WIND CONDITIONS CAUSED A B747-200 FLT CREWTO OVERSHOT THE TURN ONTO FINAL FOR RWY 24L, DUE TO XWINDS ALOFT. FLT EXPERIENCES A POTENTIAL CONFLICT WITH COMMUTER TFC ON PARALLEL RWY AT LAX, CA.
Narrative: APCH CTL CLRED US FOR THE VISUAL ON RWY 24R, TO FOLLOW ACFT IN SIGHT. ON TURNING BASE, APCH RECLRED US FOR RWY 24L. TURNING ONTO FINAL, OVERSHOT AND RECEIVED A TA/RA FROM TCASII AND COM FROM TWR OF THE TFC. TURNED BACK TO FINAL APCH COURSE, AND NO FURTHER INCIDENT. WIND AT 2500 FT WAS 310 DEGS AT 50 KTS. OUR OUTBOUND HDG FROM SMO WAS 60 DEGS TO PARALLEL RWY. WITH THIS WIND COMPONENT, A TURN TO FINAL REQUIRED AN AGGRESSIVE TURN AND A LARGE CORRECTION HDG. WITH SWITCHING TO TWR, ILS FREQS AND CONFIGURING, WE OVERSHOT FINAL. VECTORS TO FINAL WITH STRONG SANTA ANA WIND AT LOW LEVELS, INSTEAD OF VISUALS CLRED ON DOWNWIND, IS A POSSIBLE SOLUTION.
