Stagnant High Pressure

Special air quality statement issued for Grande Prairie area

Jun 29, 2021 | 4:00 PM

Environment Canada has issued a special air quality statement for the Grande Prairie-Beaverlodge-Valleyview forecast area, as the stagnant hot weather trapped under a ridge of high pressure has caused pollutants at the surface to build up in recent days.

The weather office says air quality is expected to be at its worst in the evenings while the sun and heat continue to persist. They add with this air quality, people may experience symptoms like increased coughing, throat irritation, headaches or shortness of breath.

Children, seniors, and those with cardiovascular or lung disease, such as asthma, are especially at risk.

“People with lung diseases, such as asthma and COPD, can be particularly sensitive to air pollution. They will generally experience more serious health effects at lower levels,” warns Environment Canada. “Pollution can aggravate their diseases, leading to increased medication use, doctor and emergency room visits, and hospital visits.”

As of 4 p.m. Tuesday, the Peace Airshed Zone Association had recorded a Air Quality Health Index (AQHI) of 5 (moderate risk). Their stations in Beaverlodge and Wembley both recorded a level of 3 (low risk) as of that same time.

The special air quality statement is also in effect for the Fox Creek and Whitecourt area, as well as Edmonton.

The statement runs concurrent to the ongoing heat warning for the region, as a “heat dome” continues to bring record high temperatures to the region. As of 3 p.m. Tuesday, Grande Prairie had reached 39 degrees celsius.
