Source: NOAA/NCEI Storm Events Database, 1950 to date. The early decades (tornadoes from 1950, hail and wind from 1955) are mostly tornadoes; all event types are recorded consistently only from 1996. The "notable" list is filtered to events with fatalities, major damage or a strong tornado. Damage is the reporting office's estimate. A record of past weather is not a forecast. See About the Data.
