The Enhanced Fujita Scale, or EF-scale, is an intensity scale used to rate wind damage. The scale ranges from EF0 (weakest) to EF5 (strongest). It was adopted in Canada in April of 2013, replacing the original Fujita Scale, or F-scale. The EF-scale is more sophisticated than the original F-scale, having a better correlation between wind damage and wind speed and a much greater variety of indicators with which to rate damage.
