Narrative:

While descending into [destination] our radar failed for the third time. We were visually deviating to avoid build ups and center requested for us to turn left for traffic. We were not able because of weather. Center allowed us to stay on our heading and descend to 8;000 feet MSL. He also requested we keep our speed up and slow to 250 knots indicated not at 10;000 feet MSL; but 9;000 feet MSL. We complied with his request so we could continue deviating and avoid the traffic. The situation could not be avoided due to the failure of the weather radar system.
