An air quality statement has once again been extended for Metro Vancouver and the Fraser Valley due to the wildfire smoke in the region.
There are high concentrations of fine particulate matter in the air, which are expected to persist until a change in the weather.
Global BC meteorologist Mark Madryga says that change could come this weekend — maybe even before the weekend.

“The timing for the change in the overall weather pattern is still on track to really start to kick in late Friday night,” said Madryga.
“That is a touch more marine air on late Friday, and then Saturday not as hot with a bit more cloud, but still dry.”

He said Saturday might also see some rain.
Smoke concentrations vary widely across the region as winds and temperatures change, and as wildfire behaviour changes.
People with chronic underlying medical conditions should postpone strenuous exercise until the advisory is lifted. Exposure is particularly a concern for infants, the elderly and those who have diabetes, and lung or heart disease.
If you are experiencing symptoms such as chest discomfort, shortness of breath, coughing or wheezing, follow the advice of your health-care provider.
