Coconino County within Arizona. Dots: HailTornadoFloodWind event locations in the kept record. Boundaries: US Census Bureau.

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 785 storm events in Coconino County, Arizona, led by floods and flash floods.

That is 4.2 events per 100 square miles, below the Arizona figure of 15.7, and 54.1 per 10,000 residents against 24.6 statewide.

23 events fall in the 12 months to 30 Jun 2026. NCEI attributes 31 deaths and 86 injuries to events in the county, with property damage estimated at $35M.

FEMA has designated the county in 24 federal disaster declarations since 1953; the most recent is Pipeline Fire (fire management assistance, 12 Jun 2022).

National Flood Insurance Program policyholders in the county filed 295 claims since 1978, of which 202 were paid, totalling $5.3M (about $26K per paid claim). FEMA counts 733 residential flood policies in force.

FEMA's National Risk Index rates the county's overall risk as "Relatively Moderate" and its expected annual loss as "Relatively Moderate" ($131M a year across 18 hazards).

Recorded events in Coconino County by decade and hazard group. HailTornadoFloodWindWildfireLightningOther NCEI recorded only tornadoes, hail and thunderstorm wind before 1996.

Trend: 514 events in the 20 years to 2025 against 234 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.
