CBC - it's not necessarily your neighborhood you have to worry about. Someplace upline may go down and you'll lose power.
Good advice from a pro:
When looking for a place to live try to move to somewhere on a critical path. We're on the power path to the water treatment (sewer) plant and our electricity is restored very quickly when it goes out. After Hurricane Katrina when we returned after 3 weeks, our ice cubes had barely melted in the freezer. So the power was off for less than 24 hours.
