Oregon Department of Environmental Quality has issued an Air
Pollution Advisory...in effect until 5 PM PDT this afternoon.
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:

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.
DEQs color-coded Air Quality Index provides current air quality
conditions and ranks air quality as follows: Green is good. Yellow is
moderate. Orange is unhealthy for sensitive groups such as children,
the elderly, pregnant women and those with respiratory conditions.
Red is unhealthy for everyone. Purple is very unhealthy for all
groups. Maroon is hazardous.
