What is a Dust Devil?

A dust devil is a strong, well-formed, and relatively long-lived whirlwind.

It forms when hot air near the surface rises quickly through a small pocket of cooler, low- pressure air above it.

If conditions are just right, the air may begin to rotate. Normally, this phenomenon occurs under sunny conditions during fair weather.

A dust devil is sometimes called a "dancing devil" or a "sun devil".

Now, it may LOOK like a tornado, but a dust devil rarely comes close to the intensity of a tornado. It is usually harmless.
