Most disaster-prone counties in Wyoming

Wyoming has 131 county-level FEMA disaster declarations across 23 counties. The dominant hazard type is biological. Albany County leads with 10 declarations, followed by Natrona County and Platte County.

This ranking shows every county in Wyoming ordered by how many times FEMA has issued a disaster declaration affecting it. Counties near coastlines, river systems, or wildfire corridors tend to appear at the top because the same geographic exposure produces recurring events across decades.

Each county links to a full disaster history page with the complete declaration timeline, hazard type breakdown, decade trends, and whatever FEMA spending data is available. For a national view, see the most disaster-prone counties in America page.
