The National Weather Service in Phoenix has issued a dust storm warning for Pinal County on Tuesday.
A wall of dust was along the line extending 10 miles south of Maricopa, moving west at 30 mph. Hazard warnings, according to Doppler radar, include less than a quarter-mile of visibility with strong winds at least 40 mph. These hazards could lead to dangerous, life-threatening travel.
National Weather Service warns, “dust storms lead to dangerous driving conditions with visibility reduced to near zero. If driving, avoid dust storms if possible. If caught in one, pull off the road, turn off your lights and keep your foot off the brake.” The dust storm warning will last until 5 p.m.
