You are safer outside of your automobile than inside, but an overpass is also not safe. The Fujita scale, named for the scientist who developed it, ranks tornado strength based on the damage they cause. Another pattern important for tornado detection is a hook echo. 3. Thankfully, no injuries or deaths were reported. tornado Since high frequencies of in-cloud lightning can be a warning sign a tornado has formed or could form, meteorologists and everyday users who rely on total lightning detection systems can keep an eye on in-cloud lightning frequencies to help predict.
