Calgary’s poor overnight air conditions continue on Sunday as the city is blanketed by smoke from northeastern B.C.
Environment and Climate Change Canada (ECCC) issued a special air quality statement for Calgary, rating the air quality hazard level as 10+ or “Very high risk” Saturday night, and has dropped down to a six or “moderate risk.”
The ECCC says conditions in a few parts of northeastern Alberta have improved temporarily, but added conditions will most likely remain poor through Monday or possibly Tuesday.
The smoke spreading into Alberta stems from the wildfire near Fort Nelson, in the far northeastern corner of B.C. about 1,600 kilometres from Vancouver.
The mayor of Fort Nelson says a tree blown down by strong winds fell onto a power line and started the fast-growing wildfire, which has forced the evacuation of thousands.
Parts of B.C. near Fort Nelson have a similar warning in place from Environment Canada, and people are advised to stay indoors or away from strenuous activity outside.
“Reduce sources of indoor air pollution. If you can, avoid smoking or vaping indoors, burning incense and candles, frying foods, using wood stoves and vacuuming. Dust on indoor surfaces can be removed by wiping and wet mopping during a pollution episode,” the ECCC says.
Calgary’s air quality is expected to improve later in the day but remain in the high-risk category level.
