Ranked by how often it has actually been declared here — and what goes wrong in each, which is almost never the thing people prepared for.

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.

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

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.

Do this tonight
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.

It is the car and the shovel, not the cold.
About 70% of winter storm deaths happen in automobiles. Roughly 100 more people a year die while shovelling snow, and over half of those are cardiac. The safest thing most households can do in a snowstorm is stay off the road, and stop shovelling before they are tired rather than after.

Decide now what would actually make you drive in a snowstorm. Most of the reasons people give themselves at the time do not survive being written down in advance.

The days after are more dangerous than the landfall.
The wind stops, the power stays off, and the generators come out. After Hurricane Ida, Louisiana hospitalised dozens for carbon monoxide poisoning inside the first 48 hours. Cash matters here too — when the grid is down the card readers are down with it, and the store that is open cannot take your money.

Do this tonight
Put two hundred dollars in small bills somewhere you will not spend it, and check that your medication buffer covers a week.

Underestimated because of the name.
The rain and the outage do the damage, not the wind — which means the same generator and floodwater failures that follow a hurricane follow this too.
Do this tonight
Treat the preparation as identical to a hurricane. The name is the only thing that is smaller.

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.

Write down every prescription in the house with its dose, and find out how early each one can be refilled.
