Tornado Database

Click HERE for the regional tornado database.

This database contains all known tornadoes that have occurred in the NWS St. Louis County Warning Area (CWA) from 1805 to present and is updated on a regular basis. Statistics previous to 1950 were taken from an extensive database of killer and significant tornadoes (F2-F5) compiled by Tom Grazulis (1993). After 1950, all tornadoes were gathered from either the Storm Prediction Center or the National Centers for Environmental Information Database. Tornado intensity is determined by using the F/EF-Scale and the time is in Central Standard Time (CST).
