VANCOUVER — At the start of last week, a large area of British Columbia was under heat warnings. This week, it’s smoke. Environment Canada has issued special air quality statements for 20 parts of the province, all due to wildfire smoke. An interactive map from the government shows much of B.C. is burning. As of Monday morning there were 196 active fires across B.C., the majority of which are lightning-caused. About one-third are considered out of control. …Essentially, the clouds are creating their own weather, the Environment Canada expert said. It’s a trend also seen as Fort McMurray burned in 2016, in B.C. during the wildfire season of 2017, and in Australia when wildfires tore through much of the country last year. …Air quality statements issued Sunday and renewed Monday morning suggest wildfire smoke will be noticeable over the next 24 to 48 hours.
