6 preliminary tornado reports in Arizona since December 29, 2025
These are 6 preliminary reports, not confirmed tornadoes. They have not yet been through an NWS damage survey, and are not counted in the confirmed totals above.
Preliminary reports are revised, merged, and sometimes withdrawn — historically about 23% are consolidated downward once surveys complete. Ratings are omitted until a survey assigns one.
Confirmed records above are complete through December 29, 2025. NOAA publishes the confirmed archive annually, so tornadoes after that date appear here first and move into the totals above once finalized.
