Tulsa County, Oklahoma: hazard history

What federal records show has already happened here: disaster declarations, storms, and flood insurance claims. This is a record of the past. It is not a forecast and not a hazard score.

What this means

  • The event NOAA recorded most often here is Hail, with 852 records.
  • The costliest single record is Thunderstorm Wind in 2023: $160.0M in property damage, in the dollars of that year.
  • The deadliest record is Heat in 1998, with 3 deaths.
  • FEMA has declared 40 disasters that named this county, most often for severe storm.
  • The worst year for flood insurance claims was 1984, with 1,539 claims.

What this can't tell you

  • What happens next. Past events do not set the odds of the next one.
  • Anything before 1996 from NOAA. That is when NOAA began recording every event type; earlier files hold only tornado, hail and wind, so they are left out on purpose.
  • Today's cost. Damage and payments are in the dollars of the year they happened.
  • A flood rate. NFIP counts claims but not how many homes were insured, and many flooded homes carry no flood insurance.
  • Earthquakes, wildfire perimeters or radar-detected hail. Those records are not tied to counties.

Records start in 1996. Damage is NOAA's estimate at the time, in nominal dollars, and is often rounded; it is not insurance claims data. A storm that crossed two NOAA zones in this county is recorded, and counted, once per zone. A storm filed against a forecast zone is counted in every county that zone covers, with the whole storm's damage; do not add these figures across counties.

Hazard vulnerability analysis: the probability column for a facility in Tulsa County

A hazard vulnerability analysis rates each hazard for probability, impact, preparedness and response. Probability is the one column the county’s federal record can fill — NCEI storm events from 1996 to 2026 and FEMA declarations naming the county — and this is what it says for a facility here, on the 0–3 scale of the all-hazards structure surveyors expect. The other six columns are the facility’s own judgment about its building, and Calchis leaves them blank.

A dash means the record does not speak to that hazard; it is not a zero. Whether a finished document satisfies the CMS Emergency Preparedness Rule is the facility’s finding and its surveyor’s. Complete the HVA for a facility in Tulsa County — the technological, human and hazardous-materials rows, the six facility columns, the approval and the printed document — or read the sample analysis on that page first.

How this page was made

  • Every figure is counted from public federal records held by Calchis: NOAA NCEI Storm Events, FEMA OpenFEMA Disaster Declarations, and FEMA NFIP claims. Nothing is modeled or estimated.
  • NOAA files some events against a county and others against an NWS forecast zone, and publishes a code for both. Records are counted as Tulsa County by that code — county records by the county's own FIPS code, zone records through the National Weather Service's published list of which counties each zone covers. No name matching is involved. Of 2,146 records, 1,886 were filed against this county and 260 against a forecast zone covering it. A zone storm is counted in every county its zone covers, and its damage figure is the whole storm's, not this county's share — NOAA does not publish that split. So these figures describe this county; they must not be added up across counties. Left out: 1% of Oklahoma's NOAA records, which are marine zones or zones NWS does not map to a county.
  • Counts last rebuilt from the source records on Sep 15, 2026.
