Forecast Discussion:
An Ozone High Pollution Advisory is in effect for the Tucson metro area today.
Active weather last night helped to lower particulate matter concentrations this morning. With more storm activity expected tonight, we expect PM10 (dust) to remain well within the Good AQI category going forward. PM2.5 (smoke) levels will hover around the Good/Moderate AQI threshold during that same timeframe.
As for ozone, levels are forecast to remain relatively elevated through the weekend, but dropping slightly as an upper level wind shift and increased cloud cover will help to lower concentrations. We will continue to monitor wildfire smoke that has affected a few of our ozone sites this past week.
Have a great weekend!

Ozone and Your Health
People most vulnerable to the impacts of air pollution include children, older adults, adults exercising outdoors, people with heart or lung disease, and those suffering from asthma and bronchitis. Exposure to ozone can increase the number and severity of asthma attacks, cause or aggravate bronchitis or other lung disease, and reduce the body's ability to fight infection. Symptoms may include itchy eyes, nose and throat, wheezing, coughing, shortness of breath, chest pain, and upper respiratory issues | View Ozone Fact Sheet >
Please help reduce ozone by doing one or more of the following:
- Drive as little as possible, carpool, use public transit or telecommute
- Re-fuel your vehicle in the evening
- Avoid waiting in long drive-thru lines, if possible
- Use low-VOC (Volatile Organic Compounds) or water-based paints, stains, finishes and paint strippers - delay big painting projects
- Make sure containers of household cleaners, garage and yard chemicals, and other solvents are sealed properly to prevent vapors from evaporating into the air
