Forecasters issue tornado warnings when they spot strong rotation on Doppler radar, or when trained spotters report a tornado in progress. If there’s a tornado warning, the danger is real whether you can see it or not. It’s best to head for safety...
Storm chasers can spend 12 hours or more driving around and still not see a tornado of any kind. Byron Turk, navigator for the Discovery Channel's Storm Chasers series, describes the process like this: We find the storm hopefully before it gets dark, and hopefully it produces a tornado, ...

Since we're interested in the intensity and destructive power of storms, we also need to know how scientists classify them. The Enhanced Fujita (EF) Scale measures tornado intensity on a 0-5 scale by estimating wind speeds based on damage. Interestingly, this means very powerful tornadoes can...
