Narrative:
We were cleared to descend to 2500 MSL to set us up for ILS approach to runway 1, passing through 2900 MSL we received a GPWS warning of terrain! Terrain! Whoop pull up! Being in the clouds I immediately rotated and applied full power until the warning stopped. I ended up leveling at 4000 MSL. I queried the controller and he said 2500 was a good altitude in that area. The initial approach altitude is 2500 ft. There are towers and a mountain ridge in the area we were at but obviously it was a false warning but regardless you have to react to a warning of that magnitude when you're not totally sure your safe. Definitely caught my attention.
