A health advisory for all of the Front Range prompted by Canadian wildfire smoke until Wednesday afternoon.
The advisory includes the cites of Denver, Fort Collins, Greeley, Boulder, Colorado Springs, Pueblo, Trinidad and Lamar. On the Eastern Plains, all of Crowley, Kiowa, Otero, Bent, Prowers, Las Animas and Baca counties are also affected.
The advisory, first issued Monday night, is in effect until 4 p.m. Wednesday.
“If smoke is thick or becomes thick in your neighborhood you may want to remain indoors,” the Colorado Department of Public Health and Environment says. “This is especially true for those with heart disease, respiratory illnesses, the very young and the elderly.”
Health officials say if visibility is less than five miles in smoke, unhealthy levels have been reached.
“Increasing atmospheric mixing along with some showers and thunderstorms may bring improved conditions at times by Wednesday afternoon,” CDPHE said. “However unhealthy levels of smoke will continue periodically over the advisory area.”
The thick haze in Denver on Tuesday was blamed for morning delays at Denver International Airport.
Heath Montgomery, a DIA spokesman, said the Wednesday haze is creating low visibility but not leading to the kind of delays the airport saw Tuesday.
