A dust storm warning went into effect in Central Arizona this morning across western portions of the Phoenix metropolitan area, according to a report from the National Weather Service.

Winds of up to 50 mph struck the area, causing visibility to drop to near zero in some areas.

“Be ready for a sudden drop in visibility to near zero. If you encounter blowing dust or blowing sand on the roadway or see it approaching, pull off the road as far as possible and put your vehicle in park,” says the National Weather Service warning.
