Tropical Depression disasters in the United States

How common are Tropical Depression disasters in the U.S.?

FEMA has issued 1 federal disaster declarations classified as tropical depression between 2025 and 2025, affecting 1 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.

This disaster type's footprint is thin and scattered across the map. The three states with the most tropical depression declarations on record are NC (1 declarations), consistent with how narrowly this hazard type is geographically concentrated.

With so few declarations on record, the year-by-year pattern is necessarily sparse. Trends over the 0+ year history reflect how infrequently this disaster type crosses the federal declaration threshold at all.
