Why it matters
Dust storms in the region are triggered by strong outflow boundaries from approaching storms, which can rapidly reduce visibility to zero and create hazardous travel conditions. The National Weather Service monitors these events to warn motorists of sudden, dangerous obstructions to road safety.
The event featured wind gusts ranging from 35 to 45 mph across the Phoenix area. Visibility was reported as dropping to zero across key routes including Interstate 10, Interstate 17, and U.S. 60.
