Think through where you might end up: at a shelter, a friend's house, or stuck camping out of your car.
Do this before you think you might need to. Dedicate a corner of your garage to it. If you have no garage, pick the closet closest to your front door and make sure everything is packed neatly into cheap duffle bags so the family can throw everything in the car within 15 minutes if they need to. Change the water and medications every year (your birthday is a good time to do that) and recharge the spare phone battery.
I also put a water filter in my supplies and parachute cord. Think through your locale, your situation, and add whatever you want.
And NEVER let your gas tank go under 50% full. Because you really never know.
