What’s Causing Our Hazy Skies


As a massive wildfire consumed tens of thousands of acres of forest land and homes around Los Angeles, newspapers around Colorado, such as the Craig Daily Press and the Steamboat Pilot & Today, reported that yesterday’s hazy skies were partly the result of the smoke billowing from about 1,000 miles west of Denver. Winds also brought ash and particles from other fires in Utah and Arizona. Mix that with the state’s unusually high humidity, and you get a strange, gray-blue haze with a reddish glow, which is expected to linger around the state through today (via 9News). Norv Larson, a meteorologist with the National Weather Service in Grand Junction, says a high-pressure system from the Arizona-New Mexico border is creating the airflow that’s bringing the smoke here. “Looking at satellite trajectories, we can follow it all the way back to California,” Larson tells The Denver Post. “There is a long line of smoke. These fires are so large and burning so hot, they’re generating their own weather and lofting smoke thousands of feet into the atmosphere.” As for the massive Station wildfire in Los Angeles, it has shown little signs of slowing, after destroying more than 50 buildings and burning more than 105,000 acres of brush land, reports the Los Angeles Times.
