A short kit for its top hazards, what to check before you buy, and where neighbors get alerts.

When the river rises
  • Turn around at flooded roads: a foot of moving water can carry off a car.
  • Flood insurance usually takes 30 days to start, so buy it before the forecast.
  • Keep papers and medicines up high, in a grab-and-go bag.

Cold snaps
  • Let faucets drip so pipes don’t freeze.
  • Know where your water shutoff is.
  • Never heat the house with the oven or a grill.

Winter storms
  • Keep a shovel, a blanket and snacks in the car.
  • Clear snow from furnace and dryer vents.
  • Check on older neighbors when the power goes out.

How to read this page

What these numbers can and can’t tell you

  • An average, not a forecast. FEMA’s National Risk Index estimates the damage 18 kinds of natural hazards cause in a typical year, from decades of records and models. A quiet decade can follow a bad year.
  • Compared by rate. “Higher than N%” compares yearly damage as a share of what’s there, so a big city isn’t rated riskier just for having more buildings.
  • Money that reached town. Flood claims are matched to St. Charles’s own flood-insurance community; household aid to the registrant’s city; repair grants to St. Charles.
  • It follows property value. FEMA’s model weighs damage to buildings, so a place that recently lost many homes can rate lower than it feels.
