Ozone levels are forecast to be highest between the hours of 11:00am - 6:00pm.
Currently, the atmosphere overtop the desert southwest is in a transition between exiting systems continuing to move off the east, and the arrival of new systems moving in from the west. Lightest winds are expected today and tomorrow in the valley, with southwest winds of 5-10 mph building later in the afternoon.
By the weekend, wind will increase again, improving ventilation and lowering high temperatures for a few days. Early next week, stagnant conditions will envelop the region, likely increasing high temperatures into the triple digits and another chance for ozone levels to increase.
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 the ADEQ Ozone Fact Sheet below.
