According to ready.wv.org, you should keep water, flashlights, a radio, food, medicines, and bank records available and handy in case of an emergency.
Carl Sizemore, the Assistant Director at the Wood County Center for Emergency Management says to also have some sort of secondary generator that is in working condition in case of long periods of power outage.
Sizemore says, "you should have an emergency kit, not only for your vehicle, a lot of people have them for their vehicles, but you should have one for your residence also. If the power was going to be out for that long, of course you would want to have plenty of flashlights and extra batteries on hand."
Sizemore also says that you should make sure you are practicing fire safety when lighting multiple candles at once, in case of power failure.
