Blowing dust barreled into the Phoenix metro early Monday, quickly turning a Chandler freeway camera view into a murky blur and prompting warnings from weather and traffic officials. The dust plume rode in on gusty outflow winds that kicked up dust across the Valley within minutes, and drivers were urged to be extra cautious as visibility dropped on some east-valley stretches.
Dust has moved into the Valley with the stronger outflow winds moving in now. This @ArizonaDOT cam is from Chandler. Drive with care.

What officials posted
The National Weather Service warned Monday morning that “dust has moved into the Valley with the stronger outflow winds moving in now,” and an Arizona Department of Transportation camera from Chandler showed the reduced visibility, according to NWS Phoenix. The posts encouraged motorists to slow down and, if possible, avoid driving straight into the dust.
How to stay safe on freeways
Arizona Department of Transportation's long-running “Pull Aside, Stay Alive” guidance says drivers should exit the roadway completely when dust reduces visibility, turn off vehicle lights, set the emergency brake and remain buckled inside the car until conditions improve, per ADOT. The Arizona Department of Public Safety echoes those steps and adds that you should not stop in travel lanes or rely on other vehicles' lights as a guide, AZDPS notes.
Why these dust events can be sudden
Outflow winds from thunderstorms can push a surge of strong, gusty wind across the desert surface and loft dust into a fast-moving wall that cuts visibility to near zero, an event sometimes called a haboob, the National Weather Service explains in its background materials. These outflow-driven dust events can happen quickly and without much lead time, which is why officials rely on cameras and social updates to alert drivers, according to NWS Phoenix.
Where to get real-time updates
The Arizona Department of Transportation directs drivers to AZ 511 for up-to-the-minute road closures and live camera feeds that can help motorists decide whether to delay or reroute. If a dust wall is approaching, safety officials reiterate the same guidance: pull completely off the pavement, turn off your lights and wait until visibility recovers.
