What gets declared in South Dakota

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.

Severe storms

9 declarations in South Dakota

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.

Flooding

5 declarations in South Dakota

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.

Winter storms

3 declarations in South Dakota

Two things kill, and neither is the cold on its own.

Carbon monoxide, when the heat fails and people bring a generator or a grill inside — generators are the single largest source of non-fire CO deaths. And hypothermia, which claims around 1,300 Americans a year. The house going cold is survivable. What people do about it is what is not.

Do this tonight

Find your water shutoff and make sure somebody other than you knows where it is. Frozen pipes do more damage than the cold ever will.

Public health emergencies

1 declaration in South Dakota

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.

Do this tonight

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