EvacuationThis is the one that leaves you dark for a week.
Ice brings the lines down across a wide area at once, so restoration runs into days rather than hours. That is what makes it dangerous — the longer the power is off, the more likely somebody brings a generator or a grill somewhere it should not be.
Work out how you would keep warm for five days without the furnace, and make sure the answer does not involve burning anything indoors.
