The US state of Arizona is used to dust storms but not many of them are this big.
The giant cloud of dust and sand swept across Phoenix and surrounding areas on Tuesday bringing transport chaos with it.
Phoenix Sky Harbor Airport was temporarily closed.
Motorists were forced to pull over as visibility fell.
The storm came in with sustained winds of 112 kilometers an hour and stretched for almost 50 kilometers.
Large sandstorms are fairly common in Arizona between May and September because of high heat and low moisture in desert areas.
But this one was definitely on the larger end of the scale.
