Harrison County, Mississippi
Recorded hazard history: storm events since 1950, federal disaster declarations since 1953, flood insurance claims since 1978, and FEMA's risk index.
NCEI notes that Storm Data is compiled from a variety of sources including the National Weather Service, other federal, state and local agencies, the media and the public; that property and crop damage figures are estimates; and that some events are recorded by NWS forecast zone rather than by county. FEMA notes that NFIP claim records are redacted and aggregated to protect the privacy of policyholders. NCEI storm records through 30 Jun 2026; OpenFEMA declarations refreshed 1 Oct 2026; NFIP claims as of 8 Sep 2026.
Between 1950 and 2026, NCEI recorded 622 storm events in Harrison County, Mississippi, led by damaging wind.
That is 108.4 events per 100 square miles, in line with the Mississippi figure of 89.7, and 29.7 per 10,000 residents against 142.8 statewide.
39 events fall in the 12 months to 30 Jun 2026. NCEI attributes 112 deaths and 90 injuries to events in the county, with property damage estimated at $8.9B.

Events by decade
Trend: 311 events in the 20 years to 2025 against 188 in the 20 years before. Reporting practice changed in 1996 and again with automated reports in the 2000s, so decade totals measure the record as much as the weather.
Events by type
Hazard pages exist for hail, tornado, flood, wind and winter where the county has at least 10 recorded events. "Other" covers heavy rain, debris flow, dust, funnel clouds and similar reports.
