The Colorado Department of Public Health and Environment says the advisory applies to the towns of Durango, Vallecito and Bayfield and is expected to be in effect until at least 4 p.m. Sunday. The young, elderly and people with heart disease or respiratory illness are being asked to stay indoors if the smoke becomes too thick.
The fire was reported Oct. 16 and has burned about 800 acres west of the Vallecito Reservoir. Fire managers are still trying to determine the cause of the blaze, which is 25 percent contained.
