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.

Tornado warnings
  • Pick your spot now: the lowest floor, an inside room, no windows.
  • A watch means be ready; a warning means take cover now.
  • Keep shoes and a flashlight by the bed.

High winds
  • Trim dead limbs over the house and driveway.
  • Tie down trash cans and outdoor furniture.
  • Stay clear of downed lines and call the utility.

Before you buy or rent
  • Look up the address on FEMA’s flood map.

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 Gibson’s own flood-insurance community; household aid to the registrant’s city; repair grants to the City of Gibson.
  • 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.
