Forecast Discussion:

An Ozone High Pollution Advisory is in effect for the Tucson metro area today and tomorrow. In addition, an Ozone High Pollution Watch is in effect for Saturday. The ozone levels are highest between 11 a.m. and 6 p.m. We recommend limiting your outdoor activity if you are outside for a prolonged period of time. Satellite imagery this morning shows wildfire smoke continuing to move into the southwestern U.S., resulting in higher ozone levels.

Going forward, evening storm chances will be possible over the next few days, with rain chances tapering early next week. Blowing dust chances will be minimal as prior rainfall helped to stabilize local soils. By early next week, wind will shift out of the southwest as low pressure moves to the north. By mid-week, high pressure will reestablish over the Four Corners, bringing back monsoonal moisture into the area.

Check in with us tomorrow for the weekend forecast.

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
