A dust storm with winds up to 40 mph swept through the Phoenix area Tuesday.
Tuesday's storm traveled northwest through the suburbs of Phoenix.
It reached downtown Phoenix at about 6 p.m. Arizona time.
Here's what it looked like from a plane leaving Phoenix Sky Harbor airport.
Authorities said the dust storm was blamed for five non-injury crashes on Interstate 10 north of Picacho Peak.
The storms can greatly reduce visibility, and motorists are encouraged to pull over to the side of the road during them.
A drone in Gilbert, Arizona, captured aerial video of the massive storm.
