Severe Storm disasters in the United States

How common are Severe Storm disasters in the U.S.?

FEMA has issued 157 federal disaster declarations classified as severe storm between 2016 and 2026, affecting 41 states and territories. Each declaration represents a formal federal recognition that an event exceeded state and local response capacity, unlocking Public Assistance, Individual Assistance, or Hazard Mitigation Grant Program funding depending on the declaration class (DR, EM, or FM). Raw declaration counts therefore measure the federal response footprint, which is a lagging and thresholded indicator: smaller events handled entirely at the state level never appear, and declaration thresholds have been recalibrated over the dataset's multi-decade history.

Geographic concentration is pronounced for this disaster type. The three states with the most severe storm declarations on record are KS (9 declarations), MO (9 declarations), TN (8 declarations), driven mainly by which states sit in the relevant hazard corridor. States with the fewest declarations, including NJ (1), AL (1), IN (1), generally facing less exposure to this hazard type, though physiographic coverage still varies.

Temporal patterns in the record tell a separate story. The peak year on record was 2024, with 43 severe storm declarations issued that single year, a clustering driven by major multi-state events and the federal government's declaration cadence. The most recent year on record is 2026, with 10 declarations. Trends over the 10+ year history reflect changing federal declaration policy alongside real shifts in event frequency.
