Fires in Canada will keep contributing to poor air quality Sunday in the Denver area, according to the National Weather Service.
Smoky and hazy conditions are expected to continue in Denver, with a chance of showers and thunderstorms near the mountains and the Palmer Divide, forecasters predict.
The National Weather Service has issued an air quality alert through at least 4 p.m. on Sunday for the seven-county Denver-Boulder metro area and requested that people limit driving gas or diesel vehicles.
“Although the air quality continues to gradually improve across the Front Range region, health impacts are expected to linger through Sunday afternoon due to the extended exposure to heavy smoke,” the advisory stated. “Additionally, wildfire smoke could potentially increase again late Sunday and into Monday.”
“Additional air pollution in this region may directly worsen air quality or contribute to precursors which may also adversely affect air quality,” it continued. For more information on air quality conditions in the state, go to colorado.gov/airquality/colorado_summary.aspx.
People who are in areas with thick smoke — if visibility is less than 5 miles, that’s considered unhealthy — are advised to stay indoors, especially for those who have health conditions or are young or elderly.
The forecasted highs in the mountains and high valleys on Sunday are in the 40-60s, according to the weather service in Boulder, with highs in the 70s in the urban corridor and northeast plains.
