Phoenix, Ariz. – Travel across the southern Phoenix metropolitan area is expected to be treacherous this evening as strong thunderstorm outflow winds stir up dense blowing dust. The National Weather Service (NWS) in Phoenix has issued a Blowing Dust Advisory in effect from 4 p.m. to 9 p.m. Thursday, warning that sudden drops in visibility could create life-threatening conditions for motorists.
Dangerous Driving Conditions
Gusty winds topping 40 mph are forecast to sweep across the region, lofting walls of dust that can reduce visibility to less than a mile within minutes. The most hazardous impacts are expected along key travel corridors, including:
- Interstate 10
- U.S. 60
- State Route 87
Officials caution that the rapid onset of whiteout conditions on these busy highways significantly increases the risk of multi-vehicle accidents.
Safety Precautions for Drivers
Transportation and weather officials strongly urge motorists to avoid driving during dust storms whenever possible. For those caught in a dust storm, recommended safety measures include:
- Pull completely off the road as soon as it is safe.
- Turn off headlights and taillights.
- Keep your foot off the brake to avoid rear-end collisions.
These steps help prevent accidents caused by other drivers who may attempt to follow tail lights through near-zero visibility.
Impacted Communities
The advisory primarily affects southern portions of the Valley, including communities such as:
- Chandler
- Queen Creek
- Casa Grande
- Maricopa
In addition to traffic hazards, blowing dust can significantly deteriorate air quality, posing health risks to individuals with asthma, COPD, or other respiratory conditions. Residents are encouraged to limit outdoor activity during the advisory period and keep windows closed indoors.
Advisory Duration and Outlook
The Blowing Dust Advisory is set to expire at 9 p.m. Thursday, though officials note that conditions could warrant additional warnings overnight if thunderstorms redevelop. Motorists and residents are advised to remain alert for updated forecasts and alerts throughout the evening.
