The EF-Scale is used by the NWS to measure the strength of a tornado based off of wind damage.
An EF rating of 0 indicates an estimation of 65-85 mph wind speeds, while a rating of 1 indicates 86-110 mph winds speeds.
Clark and Champaign Counties have experienced 13 tornadoes since 1990.
Below are the five most recent:
