When I lived in rural North Dakota I experienced power outages of a few hours a few times a year, a day or so once every few years, and once for three days after an ice storm. Ice storms are the worst in that part of the country because they take down power lines over a wide area.
As a society we are utterly dependent on the delivery of energy, either as electricity, gasoline, or natural or lp gas. An interruption of any of those will severely affect anyone who uses them, and we all use one or more of them, unless you live in a wood-heated cabin in the woods and never go to town to buy anything. If you want to be safe you have back-ups using different kinds of energy.
Bottom line: If your power is out, your EV won't run, and you'd be well advised not to run it to empty. Leave some charge in it in case the outage is extended. Or install solar or wind power. If the gasoline stops arriving at your gas station, your stinker won't run. If you're concerned about hurricanes, which is more likely to be available after a storm: gasoline or electricity? I don't know the answer to that, but if you live there you probably do.
