Thanks to over 560 wildfires burning across British Columbia and a westerly air flow, smoke is expected to roll back into Saskatchewan Wednesday.
Twenty-five new fires have sparked this week alone in the nations most westerly province.
Environment Canada has once again issued Air Quality Advisories for much of Saskatchewan including Regina, Saskatoon, Moose Jaw, Prince Albert and all surrounding rurals.
Individuals 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.
More than 3,000 B.C residents remain evacuated from their homes.
The smoke is expected to clear sometime on Thursday.
