A massive wall of dust pushed through the Phoenix metro area on Thursday, prompting Phoenix Sky Harbor International Airport to issue a ground stop as thunderstorms moved across the Valley. Arriving and departing flights were halted as visibility dropped sharply, and travelers were reporting delays and cancellations stacking up through the evening.
Drivers on Valley freeways reported near-zero visibility as the dust wall advanced, a dangerous condition that has caused multi-vehicle pileups in past Arizona dust events. Blowing dust can also knock out power to neighborhoods when lines are brought down by wind, and dust storms of this size often trigger air quality warnings across Maricopa County.
Who is affected
Anyone with flights into or out of Sky Harbor should expect delays, diversions, or cancellations until the ground stop is lifted and the backlog clears. Commuters on Phoenix-area highways, especially Interstate 10 south of the city where dust storms are most severe, face hazardous driving conditions. Residents with respiratory conditions such as asthma should stay indoors and keep windows closed while dust remains in the air.
If you are flying today, check your flight status directly with your airline before heading to the airport, since conditions can change quickly and rebooking options fill fast. If you are driving and a dust wall approaches, pull completely off the roadway, turn off your lights, keep your foot off the brake, and wait for it to pass. At home, secure loose outdoor items and charge devices in case wind damage causes scattered outages.
This information is based on alerts from the National Weather Service and airport operations reports.
Frequently Asked Questions
How long will the Sky Harbor ground stop last?
Ground stops tied to thunderstorms and dust are typically lifted once visibility improves and storms clear the airfield, often within one to a few hours, though delays can ripple into the evening as airlines work through the backlog.
My flight was canceled because of the dust storm. What are my options?
Airlines generally rebook passengers on the next available flight at no charge during weather disruptions, and many waive change fees. Check your airline's app first, since it is usually faster than waiting at a counter.
Is it safe to drive through a dust wall?
No. Visibility can drop to near zero in seconds, so pull completely off the road, turn your lights off, take your foot off the brake, and wait until the dust passes before driving again.
Is the dust dangerous to breathe?
Blowing dust can irritate lungs and worsen asthma or other respiratory conditions. Stay indoors, close windows, and run air conditioning on recirculate until the air clears.
