I am more with Benjamin's thinking on this.

I start with avoidance, then with first aid, followed by "long term" of a few hours progressing to a few weeks.
After that it is getting into TEOTWAWKI and a whole new ball of wax.

If I was in hurricane, fire, or flood country I would likely consider going to visit relatives in a safe zone when the weather warnings started instead of waiting for an evacuation order.
