DENVER — Coloradans with sensitivity to poor air quality likely immediately noticed a haze in the sky Monday morning, which experts are attributing to fires burning in the northwestern part of the United States.
More than a dozen fires burning in California, paired with fires in Oregon and Montana released smoke across the U.S., and it dipped into the state, although it mostly avoided the Western Slope.
The National Weather Service announced a Front Range ozone action day, meaning air pollution is high, which could be dangerous for those with sensitivity to poor air quality.
Photos accompanying the Monday warning showed the smoke, which is hanging over the Denver metro area.
