Environment and Climate Change Canada issued a special air quality statement for parts of Huron County due to wildfire smoke expected to cause poor air quality and reduced visibility.
That includes north and southern Huron County, Goderich, Bluewater and Wingham.
Air quality is expected to improve on Friday.
Residents are encouraged to visit www.airhealth.ca or www.airqualityontario.com for current and forecasted air quality health index (AQHI) values, information on health risks, and recommended actions to reduce exposure to air pollution and protect health.
While there are no federal air quality monitoring stations in Huron or Perth, residents can check the conditions for Grand Bend, Kitchener-Waterloo, and London to see general air quality trends for our region.
Grand Bend is at high risk on Thursday afternoon dropping to moderate Thursday night and low on Friday, while Kitchener and London were low Thursday and forecast as moderate on Friday.
