I live in hurricane alley here in Florida. On the short list of emergency equipment around here is a generator to help keep the fans blowing in the event of being without power for a week or more (been there before). We often talk about rotating through our long term storage food and stored water, but hardly anybody mentions rotating through your fuel. Whether it's diesel or regular I suggest putting the fuel in your car and re-filling the storage can every month or so. That way you'll always have fresh fuel in the event of an emergency.
