So let's think about the idea that water on the brake pads can freeze and cause the rotors to warp. Ok, but it will freeze after the car is parked and the pads have retracted from their contact with the rotors. So how does this attribute to warping the rotors? On the other hand, let's say the pads don't pull away from the rotors after releasing the brake pedal, and the water freezes them together. I would think that long before the rotors are HOT enough to warp, the ice would be WARM enough to melt. So how does this attribute to warping the rotors? It is a mystery.
