The 48-Hour Storm Checklist
Supplies, while stores are calm
48 to 36 hours outEverything in this block gets harder by the hour. Do it first, in one run if you can.
Papers, photos, and the plan
By 24 hours outFree, indoors, and worth more than almost anything at the store.
The house
24 to 12 hours outOutside work first, while it's safe to be outside at all.
The final hours
12 hours to landfallDuring the storm
While it passes
Stay inside, in your interior room, away from windows, until officials give the all-clear.
- Generators run outdoors only. Never in the house, never in the garage, well away from windows and doors. Carbon monoxide from generators kills people in the days around storms, quietly and fast.
- If the eye passes over, the calm is a pause, not the end. The back half arrives from the other direction.
- Never walk or drive through floodwater. Depth and current are unknowable from the surface, and most flood deaths involve vehicles.
- Landline or text over voice calls if you must reach someone; texts get through jammed networks more reliably.
