Tucson, AZ – Strong thunderstorm outflows will bring dangerous blowing dust to Southern Arizona Wednesday afternoon, creating hazardous driving conditions and possible near-zero visibility on major roadways. Winds up to 45 mph could stir up a haboob between 2 p.m. and 11 p.m., impacting travel and air quality across the region.
According to the National Weather Service in Tucson, the dust threat will be highest in Pima and Southeast Pinal counties this afternoon, then spread east toward Cochise County by evening. The Tucson metro area, Interstate 10 from the San Simon Valley to the New Mexico border, and the corridor between Tucson and Phoenix are all at risk for sudden visibility drops.
Motorists are urged to pull over and stop with lights off if they encounter dust on the roadway. People with heart or lung conditions should stay indoors to avoid inhaling airborne particles. Outdoor activities may be best postponed until after the storm passes.
Blowing dust could recur with additional storms later this week, but today’s setup poses the most widespread travel disruption.
