Remember to look out for downed power lines. If the power is out in your house, or likely to go out, turn off delicate stuff like computers, turn off heavy power users, such as air conditioners, so that when power is restored the initial load is lighter, less of a chance for a fuse or a recloser to blow.

When in the presence of a downed line, get away and call it in!

Maintain a battery capable radio and invest in some of those LED powered book lights. They go on for hours and hours.

There are some wind up radios and flashlights out there. They are overpriced and not too efficient, but they do work after a fashion.
If your car is in shape, you have a portable generator. You can buy gear to plug into the power terminals (used to be cigarette lighter) inside your car. More of a convenience for radios, music equipment than anything that needs power.

In Alaska some folks buy a disconnect device that goes with the power service point of their house. The idea is, if you're going to use a portable power generator to provide live home current on your house wiring, it is vitally important that you disconnect your house from the regular service, otherwise, you back-feed to the main system and you can electrocute a lineman.
