Canadian wildfire smoke is creating dangerous conditions across the Great Lakes as it bleeds into the I-95 corridor. FOX Weather Meteorologist Bob Van Dillen breaks down the latest track and what you can expect in your city:
Canadian wildfire smoke is back, and has already begun choking out major cities across the Great Lakes and Northeast.
Heavy plumes have created eerie, hazy skies and fiery orange sunrises and sunsets bleeding into the region, with impacts set to reach more of the Interstate 95 Corridor by Wednesday night and into Thursday.
The invasion is driven by shifting winds brought on by a cold front moving south out of Canada.
This has plunged air quality to dangerous levels, forcing indexes in parts of Michigan and Minnesota into the unhealthy “orange” and “red” zones.

As the wildfires rage out of control, some cities could see their biggest air quality challenge since the wildfire outbreaks of June 2023.

That said, while the smoke is heading toward major East Coast hubs, the absolute worst, most dangerous air quality will be concentrated in the communities closest to the active fires.
Some of those areas include the following:
Two Harbors, Minnesota
This area is positioned directly downwind of the expanding fires, with air quality pushing deep into the dangerous maroon category.
Tribal Nation of Grand Portage, Minnesota
Sitting right on the border, Grand Portage is taking a direct hit from dense Canadian smoke plumes. Reports indicate visibility has dropped to near-zero, with heavy, campfire-smelling air blanketing the region.
