The warnings will remain in effect until further notice. Cause: Hot and sunny weather in combination with local emissions has resulted in elevated levels of ground-level ozone. Smoke from the Sailor Bar wildfire burning north of Yale in the Fraser Canyon has resulted in elevated levels of fine particulate matter in the Eastern Fraser Valley. Smoke concentrations may vary widely across the region as winds, temperatures, and wildfire behaviour changes.
