Elevated pollution levels are expected today. 

A special air quality statement is in place due to the possibility of deteriorating air quality. Weather conditions are expected to cause increasing levels of ozone. Moderate risk AQHI values are expected throughout the day with the potential of short-term high risk AQHI values as a result of ozone combining with residual smoke.

###

When air pollution levels are high, everyone should limit time outdoors. Consider reducing or rescheduling outdoor sports, activities and events.

You may experience mild and common symptoms such as eye, nose and throat irritation, headaches or a mild cough. More serious but less common symptoms include wheezing, chest pains or severe cough. If you think you are having a medical emergency, seek immediate medical assistance.

People more likely to be impacted by outdoor air pollution, including people aged 65 and older, pregnant people, infants and young children, people with an existing illness or chronic health condition, and people who work outdoors, should reduce or reschedule strenuous activities outdoors and seek medical attention if experiencing symptoms.
