(Portland, OR) -- Wildfire smoke continues to clog the air in Central Oregon, the Willamette Valley, and Southern Oregon. The Department of Environmental Quality and the Lane Regional Air Protection Agency have extended an Air Quality Advisory through at least Monday night, because of smoke from the Bedrock Fire. The advisory is for Deschutes and eastern Lane counties. The Flat Fire is also triggering advisories in eastern Curry and western Josephine counties. Infants, young children, pregnant women and people with heart or lung conditions should stay indoors and use HEPA filters to reduce smoke in the air.
