Procedure
We were cleared by Approach for a Visual Approach and instructed to maintain heading 270 and 3500 ft until intercepting final. We switched to Tower and were informed of a helicopter 1000 ft right below us. We did not have visual contact. Tower instructed us to expedite our turn to final ('start your turn now direct to the numbers'). When intercepting final; leaving 3500 ft as instructed; we had a RA without previous TA. The traffic that was 1000 ft below; was now 400 ft below. We leveled off responding to the RA; maintained 3500 ft until clear of conflict and continued the approach.
A320 Captain reported a TCAS RA while turning final on a visual approach to Runway 19R LAS.
