The storm is not the emergency. The outage is.
What kills people afterwards is the generator. Portable generators cause roughly 100 unintentional carbon monoxide deaths a year in the United States, and they cluster in the days after a storm when the power is out. Carbon monoxide is odourless, and by the time you are confused enough to notice, you are too confused to act. Outside, far from the house, never in a garage with the door open.

Find out whether your generator has ever been started. If the answer is no, start it — an untested generator is a heavy paperweight with a full tank of fuel.

Where you are matters more than what you do.
Since 1996, 815 people have been killed in mobile or manufactured homes — 53% of everyone killed at home by a tornado, in housing that makes up under 6% of American homes. Anchor failure is the usual cause. If you live in one, the plan is not to shelter in place. It is to know, in advance, exactly where you are going instead.

If you live in a manufactured home, drive to your nearest sturdy shelter once, in daylight, and time it. That number is your warning threshold.

This 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.

The people who die are usually the ones who could not leave.
In the Camp Fire, 85 people died, most within the first twelve hours. Most of them were older residents whose homes burned before anyone could reach them — not people who chose to stay, people who could not get out on their own. The roads out of Paradise gridlocked and some abandoned their cars and ran. The decision that saves you is made before the smoke, not during it.

Name the person in your household who could not get out alone, and name who is responsible for them. If nobody has that job, nobody will do it.

The illness is not the whole emergency.
In June 2020, 41% of US adults had avoided medical care because of COVID concerns — 12% skipped urgent or emergency care and 31% skipped routine care. The households that struggled were the ones with a prescription, a chronic condition or a caregiving duty and no plan for any of them.

People drive into it.
More than half of all flood deaths are vehicle-related. It takes twelve inches of moving water to carry off a small car and eighteen to move a larger one. It is almost never a road you do not know — it is the one you have driven a thousand times, where you cannot see how deep it is or whether the road is still there underneath.

Photograph every room in your house. It takes about eleven minutes and it is your insurance claim. Then move anything irreplaceable off the floor.
