I'm not saying cold weather doesn't produce issues, especially for places unaccustomed to it. I'm saying the impact is on a different scale than from a natural disaster, so perhaps it's wise to reserve catastrophic language for potential catastrophes. If you use the same language for cold weather as you do for hurricanes, people might not take hurricanes seriously enough.
