Enhanced Fujita scale facts for kids
The Enhanced Fujita scale is a tornado category scale used for United States and Canadian tornadoes that began being used by National Weather Service on February 1, 2007 and in Canada in April 2013. The weakest tornadoes on this scale are classified EF0, and the strongest storms are classified EF5. The scale replaces the old Fujita scale in America.
