What do you do?

Good evening fellow cultivators, So I'm curious ......here's the possible dilemma..Bad winter storm coming in my direction my state isn't equipped as well as one might hope if the power goes out for days at a rip what should I do with my ladies in flower and veg . I don't have a back up power source..Has this ever happened to anyone what did you do what opinions or facts can you share with me I figured I'd get some ideas before the worst happens and atleast I'm somewhat prepared at what kind of action to take any help is greatly appreciated thankyou!!!
