It’s been a summer of blue skies for British Columbia’s Lower Mainland, but that’s changed with a wave of wildfire smoke rolling into the region. The Metro Vancouver Regional District has issued an air quality advisory for Metro Vancouver and the Fraser Valley due to elevated levels of fine particulate matter causing hazy conditions across the region. At a Wednesday briefing, B.C. Forests Minister Ravi Parmar said conditions were expected to worsen, with much of Southern B.C. to be affected in the days to come. “We should expect to see wildfire smoke come south in the days ahead. Weather forecasters are saying that the smoke is going to be a major factor in the next 24 to 72 hours,” Parmar said. “There are already reports of smoke hitting communities. We do expect more smoke to arrive in the central and southern interior tonight or tomorrow, and reach Abbotsford and the coast by Friday.”
