Smoke from Canadian wildfires is engulfing much of the eastern and central United States and and is expected to continue for days.

Despite expected rain Sunday night, Canadian wildfire smoke will continue to impact Michigan on Monday, officials say.

Smoke from the Canadian wildfires continues to bring potentially dangerous air quality to parts of the northern U.S., with hazy skies possible.

Environment Canada's air quality index has reported moderate to high risk since Saturday morning in Calgary, as many parts of the country struggle with the effects of wildfire smoke.

The Michigan Air Quality Division said as smoke from Canadian wildfires continues to threaten the upper Midwest, "monitors in the western (Upper Peninsula) showed a large increase surface concentrations, during Tuesday, as smoke mixed down, which sent PM-2.5 concentrations soaring into the Unhealthy and higher range."

An air quality advisory is in effect until 12 a.m., Saturday, June 7, as Michigan continues to see effects of Canadian wildfire smoke.

The Ottawa-Gatineau region is still experiencing poor air quality from drifting wildfire smoke, prompting Environment Canada to maintain its special air quality statements into Saturday.
