County storm and disaster record · FIPS 04005 · population 144,629 · 18,616 sq mi
NOAA's Storm Events Database holds 1,792 records for Coconino County, Arizona from 1950 through June 30, 2026, on 982 days; the most frequent are winter storm records (516 records). 1,006 of them are forecast-zone records, which the National Weather Service files once per zone: a county covered by several zones receives each one, so a single storm can add several records on the same day.

FEMA has issued 24 declarations naming the county since 1970, 22 of them for natural hazards; the latest for a natural hazard was “Pipeline Fire” on June 12, 2022.
