Dust Storm in Cochise County, Arizona

Strong winds associated with a passing cold front created blowing dust across Cochise county into the overnight hours. Blowing dust created limited visibility on Interstate 10, which led to a three vehicle collision about 20 miles east of Willcox. A commercial truck entered the dust storm and slowed down due to the low visibility. A freight truck collided with the commercial truck from behind, before the freight truck was struck by a bus from behind as well. Three people from the three vehicles suffered injuries.

An unseasonably strong and cold low pressure system entered northwest Arizona on October 27. As this storm system and its associated strong cold front approached southeast Arizona, strengthening pressure gradients created widespread winds and blowing dust.
