Air quality in Calgary deteriorates due to wildfire smoke

The health index in Calgary is at "moderate risk" for populations with lung or heart conditions, thanks to smoke from wildfires in B.C. and California.

Haze from B.C. and California fires could get worse next week, says Environment Canada

Wildfire smoke from B.C. and California has deteriorated the air quality in Calgary, and those with pre-existing lung and heart conditions may want to keep inside until the haze lessens.

Environment Canada bumped the city's air quality health index on Thursday to a four, which is considered a moderate risk for people with respiratory and cardiovascular issues.

They should consider reducing strenuous activity outdoors, and monitor for symptoms of discomfort.

Though the general population shouldn't have to reschedule their outdoor activities, they should be mindful of coughing or throat irritation, and head inside if these symptoms occur, according to the advisory.

On Twitter, Environment Canada meteorologists warned that the haze could get worse in Calgary next week, as the weather pattern carrying the smoke continues.

Depending on the direction of the winds, meteorologists said the smoke could also increase in Edmonton, but it is difficult to forecast at this stage.

Edmonton currently sits at an air quality health index of three, or low-risk, but is no stranger to wildfire smoke.

In August 2018, it earned the distinction of having the worst air quality in the world after smoke and haze drifted in from B.C. and blanketed the city.
