This week, several Canadian provinces and territories are facing a mix of extreme heat, thunderstorms, and poor air quality as summer weather intensifies and wildfires continue to rage.
Extreme Heat
Heat warnings are currently in effect for five provinces and two territories, with temperatures expected to soar near 30°C. In northern Alberta, including Mackenzie County and Wood Buffalo, daytime temperatures are forecast to remain high until early next week, according to CTV Your Morning’s meteorologist Kelsey McEwen. However, temperatures are expected to moderate by Wednesday. Similar heat conditions are predicted for parts of British Columbia, Manitoba, and Saskatchewan. The Northwest Territories, including Fort Simpson and Hay River, are also under heat advisories, with temperatures ranging from 29°C to 35°C. In Nunavut, areas like Arviat and Baker Lake will see daytime highs reaching the mid-to-high 20s and low 30s early in the week, with a cold front expected to bring relief by Wednesday.
Poor Air Quality
Air quality advisories have been issued alongside heat warnings, particularly in northern Alberta, Saskatchewan, and Manitoba. Wildfire smoke is causing or expected to cause very poor air quality and reduced visibility in these regions. Environment Canada has warned that air quality can vary significantly over short distances and timeframes. In British Columbia, several regions, including Fort Nelson, Whistler, and Fraser Canyon, are under special air quality statements due to the impact of fires in the Northwest Territories. Similarly, regions in the Northwest Territories and Nunavut under heat warnings are also experiencing poor air quality due to wildfire smoke.
