Smoke from western wildfires in Idaho and Colorado is expected to worsen over the weekend as it drifts east.
The Pioneer fire burning outside of Boise emitted a pillowing plume of smoke on Friday that could be seen from miles away. As of Friday night, the Idaho Department of Environmental Quality had issued an unhealthy air quality warning for areas around Ketchum, due east of the Pioneer fire.
Colorado residents are also likely to see more smoke in the area this weekend as smoke from the Pioneer fire drifts east and mixes with plumes from Colorado’s Beaver Creek fire.
On Friday, the Colorado Department of Public Health and Environment warned Northern Colorado residents that wildfire smoke will likely be visible for much of the weekend.
