A dust storm warning rolled across the Phoenix metro on Monday evening, July 13, 2026, dropping visibility on key freeways and turning the drive home into a slow crawl. Officials warned that pockets of near-zero visibility could pop up with almost no notice, and traffic backed up along several Valley routes, including stretches of I-10 near Avondale and Goodyear plus corridors around Phoenix and Mesa.
The City of Phoenix boosted the alert in a social post that retweeted the local National Weather Service office and spelled out the affected corridors. The city said the warning would remain in effect until 8:45 p.m. MST on July 13. According to the City of Phoenix, drivers in the West Valley and on east-side freeways should brace for rapidly dropping visibility and keep an eye on overhead message boards.
What the weather service warned
The Phoenix office of the National Weather Service reported that strong outflow winds from thunderstorms were kicking up dust and shoving it into the Valley, creating narrow but intense blowing-dust corridors that can knock visibility down to almost nothing in minutes. NWS Phoenix issued a blowing dust advisory for portions of Maricopa and Pinal counties and urged motorists to pull completely off the roadway if dust makes it hard to see.
How drivers should respond
State traffic officials repeated the familiar ADOT safety mantra "Pull Aside, Stay Alive." That means checking traffic around you, exiting the freeway if possible, and if you cannot exit, pulling entirely off the paved shoulder. From there, turn off your lights, set the emergency brake, and stay buckled up until conditions improve. The Arizona Department of Transportation also directs drivers to live camera feeds and closure updates on AZ 511 for real-time views of conditions and detours.
Why these storms are sudden
Monsoon outflow boundaries can shove powerful gusts and walls of dust across the Valley with almost no lead time, a recurring hazard every season. Local coverage has repeatedly documented the same pattern, see this dust surge for recent examples and context.
