THAT IS, A FULLY FORMED TORNADO. NOW, IN MEASURING TORNADO STRENGTH, WE USE THE ENHANCED FUJITA SCALE, OR THE EF SCALE THAT’S BEEN UPDATED. MAYBE SOME FOLKS MY AGE ARE A LITTLE OLDER.

Once they estimate the wind speed that could’ve caused the damage, using ground reports and Doppler radar data, they can then establish an Enhanced Fujita scale rating for that tornado.

Then, in 2007, the weather service adopted the Enhanced Fujita scale, which better reflected actual storm wind speeds based on new science. The vast majority of tornadoes are considered “weak.” ...

Here's how to check Tornadoes are classified on the Enhanced Fujita scale, which ranges from zero to five. It takes into account estimated wind speeds, observed damage and damage verified in ...
