An air-quality warning remains in effect for parts of Metro Vancouver and the Fraser Valley due to smog and wildfire smoke from a blaze that has prompted evacuation alerts for the Yale and Spuzzum areas. It comes as Environment Canada warns that temperatures in the Fraser Canyon and South Thompson regions are expected to reach 37 to 39 C this week, posing a moderate risk to public health. The smog warning spans eastern areas of Metro Vancouver as well as the central Fraser Valley, while the smoke warning covers eastern parts of the valley. It says smoke from the Sailor Bar wildfire burning in the Fraser Canyon has also resulted in elevated levels of fine particulate matter in the air. The fire has prompted the Fraser Valley Regional District to issue an evacuation alert stretching from Yale and north to the Spuzzum area, covering properties on both the east and west sides of the Fraser River.
