Scientist Explains How a Fire Tornado Forms

Extreme wildfires can get so intense that the heat from the fire can generate its own weather patterns. In rare cases, like during the 2018 wildfire in Redding California, the wildfire created its own tornado, or as it is more commonly known: a firenado. Many videos show fire formations labeled as firenadoes -- but according to atmospheric scientist Neal Lareau, only two known fire tornadoes have ever been caught on video.
