Narrative:
On a right downwind to runway 5L we were given the clearance for the visual approach. As we proceeded on the downwind leg ATC inquired if we were going to turn base leg and upon the inquiry we started to turn in for the base leg. We then received an obstacle warning alert from the GPWS (large tower) and a low level alert from ATC. We promptly arrested the descent and climbed in accordance with the GPWS guidance. Once clear of the obstacle we continued the approach without further incident. This could have been prevented with a better brief of the highest obstacle on the approach chart; better outside scanning and better situational awareness on the visual approach.
