A poor visibility forecast for the metro area is triggering indoor burning restrictions and a plea to limit driving if possible.
An “Action Day for Visibility” goes into effect at 4 p.m. Tuesday and runs through 4 p.m. Wednesday, according to the Colorado Department of Public Health and Environment Air Pollution Control Division.
“Poor visibility and an exceedance of the state visibility standard are expected on Wednesday,” health officials said in a news release. “Otherwise, good or moderate are expected. No other air quality advisories are in effect.”
Visibility on Wednesday is expected to be moderate to poor. Mandatory restrictions on indoor burning and voluntary driving reductions are for the only.
Ozone standards and anticipated carbon monoxide concentrations indicate good air quality for the Front Range on Tuesday and Wednesday.
Concentrations of fine particulates were in the good category Tuesday, but will likely increase to the moderate category on Wednesday in the Denver metro area and northward along the Platte River into southern and central Weld County, including Greeley. Unusually sensitive people, including people with respiratory illness, should reduce prolonged or heavy activities on Wednesday, the CDPHE said.
Nitrogen dioxide concentrations are expected to be in the good to moderate range on Tuesday and Wednesday. Moderate concentrations will be likely in the metro area along busy roads and highways. Sensitive people should limit prolonged outdoor activities from 6 to 10 a.m. and 5 to 8 p.m., health officials said.
The Winter High Pollution Advisory Program is coordinated by the of the CDPHE. Winter season air pollution forecasts are issued daily from Oct. 31 through March 31 at 4 p.m.
