What Wyoming faces
Each hazard’s share of the building damage FEMA expects here, and how its rate compares with the rest of the country.
River and rain flooding
Hurricanes
Shares are of FEMA’s expected building damage, the measure the grade uses; ranks compare each hazard’s building-damage rate with all 85,154 U.S. census tracts. In FEMA’s terms, river and rain flooding is FEMA’s “Inland Flooding” (rivers and streams overflowing their banks, or rain overwhelming drainage). FEMA defines coastal flooding as high or rising tides and storm surge, so surge damage is counted there. Drought isn’t listed: FEMA counts its losses in crops only.
What’s behind Wyoming’s grade
River and rain flooding is 69% of the building damage FEMA expects in Wyoming, and Wyoming’s rate of river and rain flooding damage is lower than 66% of U.S. census tracts. Next is hurricanes at 22% (higher than 84% of U.S. census tracts).
A− lower expected damage per building than 75% of U.S. towns (21,298).
Wyoming’s residents live in 3 census tracts; FEMA’s figures are combined by where they live.
In dollars, FEMA expects about $441K a year in losses across Wyoming: $280K to buildings, the rest to people and crops.
