Wildfire smoke across northern, central Alberta prompts special air quality statements
Wildfire smoke causing locally poor air quality and reduced visibility, Environment Canada says

Special air quality statements and warnings have blanketed central and northern Alberta as smoke from several wildfires moves across the province.
Environment Canada issued air quality warnings for parts of northern Alberta Friday, and special air quality statements for much of central Alberta and the far northeastern portion of the province.
The statement says that wildfire smoke is causing poor air quality and reduced visibility, but conditions are expected to improve later Friday.
Environment Canada says people may experience symptoms such as increased coughing, throat irritation, headaches or shortness of breath. Children, seniors, and those with cardiovascular or lung disease, such as asthma, are especially at risk.
The Air Quality Health Index rating for Edmonton was nine, or high risk, at 1 p.m., on Friday. Conditions in the city were expected to improve in the evening.
When the air quality index surpasses seven, Environment Canada suggests reducing or rescheduling strenuous outdoor activities, especially for children and seniors or those experiencing a cough or irritated throat.
