A Dust Storm Warning was issued by the National Weather Service in Tucson on Sunday, Aug. 23, effective until 6:45 p.m. MST for Central Pima County. The warning was prompted by a wall of blowing dust detected moving west at 10 mph, bringing hazardous conditions.
Visibility dropped to less than a quarter-mile, accompanied by strong winds over 50 mph. This dangerous situation impacted travel along Route 86 and Route 286, affecting numerous communities including Sells and Three Points. The National Weather Service urged motorists to "Pull Aside, Stay Alive" to avoid life-threatening travel.
Haboobs, large dust storms common during Arizona's monsoon season from June to September, form when thunderstorm downdrafts hit the desert floor. The term "haboob" translates to "big, blasting winds." These storms are typically short-lived, lasting from a few minutes to an hour, but can cause significant disruption.
Drivers caught in a haboob are advised to immediately slow down, check traffic, and pull completely off the roadway to a safe location. It is crucial to turn off all vehicle lights and engage the emergency brake, then remain in the vehicle with a seatbelt buckled until the storm passes. High-profile vehicles should exercise extra caution.
