An Air Quality Alert has been issued for Stevens County until
further notice due to current wildfire smoke from the Crown Creek
fire, Katy Creek fire, and Blackhawk Mountain Fire. Particulate
matter (PM2.5) levels are Unhealthy for Sensitive Groups. When air
quality is Unhealthy for Sensitive Groups, residents should take
steps to reduce exposure. Limit time outside, avoid strenuous
activity, and follow tips for cleaner air. Everyone should watch for
symptoms as a sign to reduce exposure.

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.
