LOWER MAINLAND (NEWS 1130) – There is now a heat warning in place for Metro Vancouver and the Fraser Valley, at the same time as smoke from the wildfires in both BC and south of the border prompt an air quality advisory for those two regions.
Temperatures have climbed into the mid- to upper 30s at inland locations. These conditions are expected to continue through Tuesday and into Wednesday, which is why there is now a heat warning.

Meanwhile, Geoff Doerksen with Metro Vancouver says the air quality advisory is because of smoke blowing in from the wildfires in our province, as well as in Washington State, Oregon, and California.
“Since this morning, we have measured elevated measures of fine particulate in Hope, Chilliwack, and Agassiz. And our Air Quality Forecast model shows this trend to continue throughout the day and smoke to become widespread throughout Metro Vancouver.”
With near-record heat in the forecast, ground-level ozone levels are also on the rise.
“The situation is expected to persist for several days, or until there’s a change in the current weather system. The good news is that Environment Canada has forecast the weather to change, starting on Wednesday, which could bring marine air in to displace the smoke,” adds Doerksen
You’re being encouraged to avoid strenuous outdoor activities, especially in the late afternoon and early evening. Young infants, seniors and anyone with underlying health conditions will be affected the most.
The smoke is also affecting the air quality in Whistler.
