Canadian wildfire smoke continues to shroud the US Midwest and Northeast, affecting tens of millions of Americans with hazardous air quality. As of Friday, the smoke has pushed air-quality index values to dangerous levels in cities like Chicago, Detroit, and Washington DC, prompting urgent health warnings.

FAQ
How long will the Canadian wildfire smoke last in the US?
The duration depends on wind patterns and wildfire containment. Current forecasts suggest smoky conditions may persist for several more days, especially in the Midwest and Northeast.
What air quality index is considered hazardous?
An AQI above 300 is classified as hazardous, meaning everyone should avoid outdoor exertion. Readings above 200 are very unhealthy, and above 150 are unhealthy for sensitive groups.
How can I protect my family from wildfire smoke?
Stay indoors with windows sealed, run air purifiers with HEPA filters, and wear N95 masks outdoors. Keep pets inside and avoid burning candles or vacuuming, which can stir up particles.
As the situation evolves, residents should stay informed through local news and official air quality alerts. The Canadian wildfire smoke crisis underscores the need for cross-border environmental cooperation and personal preparedness.
