Dust was back to its old tricks in the north Valley on Monday, as state traffic officials warned that windy, dusty conditions were flaring up on and off along Loop 303 near Lone Mountain Parkway and Lake Pleasant Parkway. Visibility was dropping in spots, and Arizona drivers know that can turn dangerous in a hurry.
The message from traffic officials: do not drive into blowing dust, and if a cloud suddenly wipes out your view of the road, get safely and completely off the pavement and wait it out.
According to the Arizona Department of Transportation, dust was "starting to kick up" along the Loop 303 corridor. The agency repeated its familiar warning to never drive into a dust storm and to "Pull Aside, Stay Alive." The post also listed practical steps - including setting the parking brake and taking your foot off the brake - for drivers who manage to pull off the highway but are still caught in the storm.
We're seeing dusty conditions on and off in areas along Loop 303. Remember to never drive into a dust storm and to Pull Aside, Stay Alive if one happens while you're on the road! https://t.co/hSmGA4apfM

How to react if a dust storm hits
If you cannot exit the highway before visibility collapses, check traffic around your vehicle, slow down and then pull completely off the paved roadway, according to Pull Aside Stay Alive. The guidance is clear: do not stop in a travel lane or on the emergency shoulder.
Once you are safely off the roadway, turn off all vehicle lights, including flashers, set the parking brake and take your foot off the brake so your taillights are not glowing in the dust. Then stay inside the vehicle with seat belts fastened until the storm passes. It is not glamorous, but it is how you avoid becoming part of a pileup that other drivers cannot see coming.
Monsoon season ramps up the risk
The National Weather Service notes that monsoon season, which typically begins in mid‑June, brings thunderstorms whose strong outflows can lift walls of dust and reduce visibility to near zero. A NOAA technical memo on Arizona blowing dust documents how these events have caused deadly, multi‑vehicle collisions and serious air‑quality impacts in past seasons.
That combination of sudden storms and heavy freeway traffic is why even short-lived dust "channels" along stretches like Loop 303 can quickly turn from a nuisance into a life‑threatening situation.
Plan ahead and watch cameras
Drivers headed through the north Valley are urged to check live traffic conditions and highway cameras at AZ 511 before traveling, and to pay attention to overhead message boards while on the road. If conditions start to deteriorate, the safest move is to find a turnout well off the pavement and wait for the storm to blow through, rather than trying to push on into an obvious dust cloud.
State and local agencies say they will keep posting updates as conditions change. In the meantime, the basic playbook holds: see dust, slow down, and if you cannot see, pull aside and stay put.
