Enhanced Fujita Scale

Forecasters and researchers use a wind damage scale to classify tornadoes. The original Fujita scale was developed by T. Theodore Fujita and was put into use in 1973. The scale was enhanced in 2007, with rankings running from EF (Enhanced Fujita) 0-5. The ratings were based on the amount and type of wind damage.
