PHOENIX, Arizona – A Blowing Dust Advisory is in effect this evening across the southern Phoenix metro area, with dangerous driving conditions expected from 4 p.m. to 9 p.m. According to the National Weather Service in Phoenix, powerful outflow winds from thunderstorms are kicking up thick walls of dust, dropping visibility to less than one mile in some areas.
Strong Winds and Blowing Dust Create Travel Hazards
Outflow winds from nearby thunderstorms are expected to reach speeds of over 40 mph, sending heavy dust across highways and city roads. This has prompted a Blowing Dust Advisory for much of Pinal County and southern portions of the Valley.
High-Risk Areas for Low Visibility
The most dangerous conditions are expected along major roadways, where sudden visibility loss can create life-threatening situations:
Interstate 10 (I-10)
U.S. Highway 60 (US-60)
State Route 87 (SR-87)
Communities at higher risk include:
Chandler
Queen Creek
Casa Grande
Maricopa
Motorists are urged to avoid travel if possible during the advisory window. If caught in a dust storm:
Pull off the road as far as possible.
Turn off your lights and keep your foot off the brake.
Stay in the vehicle until visibility improves.
These steps help prevent multi-vehicle accidents during whiteout conditions caused by blowing dust.
Health Risks from Poor Air Quality
In addition to traffic hazards, blowing dust can cause poor air quality, which may trigger breathing problems for:
Asthma sufferers
Elderly individuals
Children
Anyone with existing respiratory issues
Keep windows closed, use air filters indoors, and limit outdoor activity if you live in an affected area.
Advisory Timing and Possible Extensions
The current Blowing Dust Advisory is scheduled to end at 9 p.m. Thursday. However, the National Weather Service warns that additional advisories may be issued later tonight if new storms develop and create more dust outflows.
As Arizona continues to deal with its monsoon season, dust storms remain a dangerous and fast-moving threat. Stay alert, stay informed, and prioritize safety on the roads and in your home until conditions improve.
