Step 1: Water
You can also store water by filling your bathtub before the storm hits. This water can be used as emergency drinking water, or for flushing the toilet. If it is raining out, you can collect water from your downspout. I have found the easiest way is by placing a garbage bag under the spout and using a clothespin to hold it in place. When the bag gets full, pour it into your bathtub. This water is best used for flushing the toilet, unless you purify it before drinking.
Step 2: Food
When the power goes out, consume meat and dairy items first. Also try to limit the amount of time you have the fridge doors open.
Always keep frozen jugs of water in your freezer, so you can place them into your fridge to keep everything cool.
Have a way to boil water for making food and hot drinks. A simple camp stove is all you need, but do any cooking in a well ventilated area.
Step 3: Light
Something new I have found are rechargeable flashlights that plug into the wall, when the power goes out the flashlight turns on. Handy for power outages that happen when it is dark out.
Candles work fine for light but be careful. Place them only on stable surfaces and never leave them lit when you are not in the room.
Step 4: Boredom
Step 5: Safety
Also keep an emergency radio to stay informed. And have a grab and go kit ready if you need to leave.
If you decide to burn candles have a fire extinguisher nearby.
You should also unplug any electronics so they don't get damaged in any power surges.
A tarp and duct tape can come in handy if any debris breaks a window.
