What is a firenado?

Answer 1

A firenado sounds like something from Science Fiction, like the cheesy Sharknado movie, but these are a real thing.

Firenandoes are more properly known as fire whirls. They are most likely to occur in large fires, like a wildfire. The fire creates a whirlwind made of ash and flames, which then combine with the high winds that are caused by the extreme heat. The combination of the two creates eddies that spin like a tornado.

The core of a firenado can reach up to 2,000 °F, and have winds of over 100 mph. These eddies can last over an hour, cannot be put out, and will set fire to anything in their path.
