Natural disaster risk in Mississippi

How disaster-prone is Mississippi?

Mississippi (MS) sits at a low level of federally recognized natural-disaster risk, with 16 FEMA disaster declarations on record, including 11 Major Disaster declarations (DR) that triggered full federal individual and public assistance. The dominant declaration type is Severe Storm, followed by Hurricane (5), Winter Storm (2), Other (1). Declaration counts at the state level reflect the cumulative federal footprint: large multi-county events count once per state, but repeat hazard patterns across decades are visible in the breakdown below.

NOAA's Storm Events Database adds the near-term severe-weather lens. Between 2015 and 2025, Mississippi recorded 15,771 individual storm events, causing 145 fatalities and 839 injuries, with combined property and crop damage estimated at $1.2B. The most frequent event types in the state are Thunderstorm Wind (6,255 events), Heat (1,736 events), Flash Flood (1,637 events). Across the state's 82 analyzed counties, FEMA's National Risk Index flags 1 as high-risk, with an average county composite risk score of 50.9/100.

NFIP claims data is limited or absent for this state in the current extract, which usually indicates low flood-policy penetration rather than zero flood risk. The highest-Expected-Annual-Loss hazard across the state is Hurricane, estimated at $0.3B annually. Drill into individual counties for localized risk, read FEMA's hazard-specific briefings, and review insurance and flood-zone designations, state-level averages can mask sharp county-to-county differences in exposure and resilience.
