Mesa County Health Department officials have issued a Health Advisory due to the smoke filling the Grand Valley. They say smoke concentrations are greatest in morning and evening hours.
The Health Advisory is for individuals who are sensitive to smoke, including those with heart disease, respiratory illness, the very young and the elderly.
Health officials says those people should avoid prolonged outdoor exertion while the smoke remains in Grand Valley air. This advisory is in effect until Wednesday and officials say they'll issue further updates as needed.
