Most disaster-prone counties in Missouri

Missouri has 2,823 county-level FEMA disaster declarations across 115 counties. The dominant hazard type is severe storm. St. Louis County leads with 34 declarations, followed by Ray County and Webster County.

This ranking shows every county in Missouri 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.
