Oklahoma natural disasters

The state's storm and disaster record · population 3,952,634 · 77 counties and county equivalents

NOAA's Storm Events Database records 82,919 storm events in Oklahoma since 1950, 63,696 of them since 1996 when every event type began to be recorded, and the Storm Prediction Center counts 4,516 tornadoes in the state since 1950. The most frequent records are hail reports (31,601). In NOAA's storm record since 1950, the deadliest tornado day in Oklahoma was May 3, 1999: tornadoes and the storms that came with them killed 40 people in the state; the deadliest of them in Oklahoma, the Bridge Creek/Moore tornado, killed 36 (SPC). FEMA has made 259 declarations for Oklahoma since 1955, 240 for natural hazards; 99 were major disasters.

The record, 1950 to 2026

Storm events recorded in Oklahoma each year (2026 to June 30, 2026). Before 1996 NOAA recorded only tornadoes (from 1950), thunderstorm wind and hail (from 1955).

What were the deadliest disasters in Oklahoma?

The storms with the most deaths since 1950, from the National Weather Service's own entries. NOAA files one storm as several records when it crosses forecast zones and counties or changes type, and groups them under one episode; each row here is an episode, with its totals and the narrative of its deadliest record. Before 1996 tornado records carry no episode and stand alone. The narrative says what happened: some deaths the National Weather Service files under a weather type had another cause beside the weather.

A damage figure marked "step" is a record from before 1993: NOAA then filed damage by category, and the figure is the category as entered, in the dollars of that year, not an estimate of the loss.

Source: NOAA NCEI Storm Events Database: deaths direct and indirect, as filed in this state, summed over the records of each episode (EPISODE_ID); a forecast-zone record counts the zone's deaths once. A tornado's whole-track deaths (SPC), on the state's tornado page, can be higher when the track crossed a state line. Storm names from the titles of FEMA declarations that name the storm's counties.
