You want to be prepared to leave your home on a minute's notice and have all the things you want to take ready, including important papers (including insurance documents), medications, phone charger, etc.
You also need to be prepared to remain in your home for at least three days and have the food, water, medications, to sustain you.
There are also lots of other events that require preparedness - pandemic preparedness, wilderness preparedness if you camp...
And in this era of shrinking public budgets, it wouldn't hurt to know CPR and first aid if you live in a rural area - it can take a while for help to get to you.
