The Oregon Department of Environmental Quality, and the Lane Regional Air Protection Agency have continued an Air Quality Advisory, which is in effect until further notice. An Air Quality Advisory for Smoke remains in effect. Wildfires burning in the region combined with forecasted conditions will cause air quality to reach unhealthy levels at times until further nortice. Pollutants in smoke can cause burning eyes, runny nose, aggravate heart and lung diseases, and aggravate other serious health problems. Limit outdoor activities and keep children indoors if it is smoky. Please follow medical advice if you have a heart or lung condition. More information about air quality can be found at: www.oregon.gov/DEQ www.lrapa.org

Oregon Department of Environmental Quality has issued an Air Pollution Advisory...in effect until 11 AM PDT Monday. The Oregon Department of Environmental Quality issued an air quality advisory for Eastern Douglas, Klamath and Lake counties due to numerous wildfires burning in the region. DEQ also expects intermittent smoke in Jackson County through at least Monday due to smoke from surrounding fires. The wildfire smoke combined with forecast conditions will cause air quality levels to fluctuate and could be at unhealthy levels. Smoke levels can change rapidly depending on the weather and planned burn operations. Smoke can irritate the eyes and lungs and worsen some medical conditions. People most at risk include infants and young children, people with heart or lung disease, older adults and pregnant people. People can take the following precautions to protect their health: - Follow local burn restrictions to prevent deteriorating air quality. - Avoid strenuous outdoor activity during periods of poor air quality. - People with heart or lung problems and young children are especially vulnerable. These people should stay indoors while smoke levels are high. - Use certified High Efficiency Particulate Air (HEPA) filters in indoor heating, ventilation, cooling and air purification systems. - Avoid using wood-burning stoves and other sources of indoor smoke if possible.
