In my NON INFORMED opinion, the preparedness for each one of these is the same TO A POINT.

1. Have foodstuffs on hand and a way to prepare them.
2. Have potable water, in quantity and a way to purify it or more.
3. Have a way to procure or have your own portable shelter to include bedding of some sort.
4. Remaining unseen as much as possible, unless you want to be seen.
5. A means of DEFENSE if you cannot remain "Hidden".
