NOAA Current Watches-OR

Oregon Department of Environmental Quality has issued an Air Quality Advisory...in effect until 11 AM PDT Tuesday. The advisory is in effect for all of Klamath County, including Crater Lake, Chemult, Crescent, Chiloquin, Klamath Falls, Sprague River, Beatty, and Bly. Wildfires burning in the region 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. People 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.
