Fill your freezer with gallon ziploc bags of water and let them freeze in advance of a storm. Move some to your fridge. They will keep your food cold for a while if the power goes out. Don't open the fridge and let out the cold air.

Buy staple foods like canned tuna, peanut butter crackers, cereal. Get an adaptor for your car so you can charge devices with your engine if you need to. Be sure to have full tank if a storm is predicted. During winter or hurricane season, try not to let your tank get below half full.
