Oregon Department of Environmental Quality has issued an Air Quality Advisory...in effect until 4 PM Wednesday for northern Klamath and Lake Counties... Wildfires burning to the north in central Oregon and Washington combined with northerly winds will cause air quality levels to fluctuate and could be at unhealthy levels. Smoke levels will change over the next few days due to varying wind direction and fire activity. 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.
