Air Quality Warning Continues as Smoke Gradually Clears Over Winnipeg

WINNIPEG – A thick blanket of wildfire smoke continues to hover over Winnipeg early this morning, significantly reducing visibility to 4 km and triggering an Air Quality Warning for the city. The good news: smoke is expected to clear from the Red River Valley and Interlake regions by midday, transitioning to hazy skies. While the sunshine and warmer temperatures may seem inviting, outdoor activity should remain limited until air quality improves.

Weather Trivia

Did you know?
The Red River Valley’s geography makes it highly susceptible to air stagnation, which traps smoke and pollution near the surface. Winnipeg, with its flat terrain and proximity to major fire zones, frequently experiences air quality degradation during wildfire season, even when fires burn hundreds of kilometres away.
