An air quality advisory in effect for the Lower Mainland and valley due to wildfires in B.C. and Washington State has been updated to include ground-level ozone.

Metro Vancouver Regional District issued an alert Sunday (Aug. 27) saying it is continuing the advisory due to high concentrations of fine particulate matter that are expected to last until there is a change in the weather, as well as high concentrations of ground-level ozone, due to hot and sunny conditions combined with wildfire smoke.

The initial advisory began Aug. 25 and will remain in effect until further notice for all of Metro Vancouver and the eastern and central Fraser Valley.

It noted that smoke concentrations may vary widely across the region as winds, temperatures, and wildfire behaviour change.

Environment Canada recommends postponing or reducing outdoor physical activity while fine particulate matter and ozone concentrations are high, especially if breathing feels uncomfortable.
