High-risk air quality conditions are expected to continue until the late afternoon in an adjusted forecast issued at 5 a.m. this morning by Environment Canada.

The Air Quality Health Index (AQHI) climbed to 10 overnight and Cochrane is currently blanketed by thick smoke. Air quality is forecasted to gradually improve to the moderate risk of 4 on the AQHI scale by 4 p.m. Forecasts, though, are subject to regular adjustment.

Forest fires continue to rage in northern Alberta and have blanketed most of the province with thick smoke, causing poor air quality and reduced visibility.  In southern Alberta, the thickest smoke is expected to move northwestward later this morning as the flow continues to shift to southeasterly. However, conditions may remain hazy into the weekend.

Individuals may experience symptoms such as increased coughing, throat irritation, headaches or shortness of breath, says Environment Canada officials. Children, seniors, and those with cardiovascular or lung disease, such as asthma, are especially at risk.

Environment Canada officials recommend staying inside if you have breathing difficulties. Find an indoor place that's cool and ventilated. Using an air conditioner that cools and filters air may help. If you open the windows you may let in more polluted air. If your home isn't air-conditioned, consider going to a public place that is air-conditioned.
