Narrative:
I was the pilot monitoring (pm) on this flight to lan. We were flying a visual approach to 28L. There are a couple of towers south of the final approach course that must be avoided--we had discussed these towers earlier in the evening as well as previously in the week. The captain (pilot flying) was descending to 2;400 feet on a base leg that would intercept the final approach course a mile or two outside of burye. We could see all the towers; and we were just above and just to the west of the 1878 feet tower. We were either in a very shallow vs descent or had gotten altitude cap when the egpws caution sounded. This was followed almost immediately by the egpws warning (obstacle; obstacle; pull up). The PF disconnected the automation and began a climb. We were clear of the obstacle right away and we were able to fly a normal; stable approach and land without further incident. I suspect that the cold temperature may have been a factor in this incident. Had we calculated the temperature induced altimeter error we probably would have found that we did not have as much vertical clearance as we thought we did.
