Air Quality Outlook
Yesterday’s storm passage brought gusty
winds to the areas around the South Fork Complex and Bald Sisters fires
resulting in a noticeable clearing of the air in surrounding communities.
Today’s elevated humidity and lower
temperatures will dampen fire behavior to primarily smoldering and creeping
activity. Smoke impacts will be
localized and potentially heaviest during early to late morning hours reflecting
drainage flow during those times into affected valley communities. Transport winds will be from the west
to northwest mostly providing relief to Oregon communities from the fires in
northern California.
Tomorrow will see similar
temperature and humidity conditions.
Fire behavior is not expected to increase. Smoke impacts to
communities closest to the South Fork Complex and Bald Sisters fires are
expected to be limited to down drainage impacts during early morning
hours. Transport winds will be
northerly.

Actions
to Reduce Smoke Exposure
|
||||
Good
|
Air
quality is satisfactory and poses little or no health risk
|
None
|
||||
Moderate
|
Air
quality is acceptable for most.
There may be moderate health concern for a very small number of
individuals.
|
Sensitive
individuals such as those with heart or lung disease, infants, children,
pregnant women, or older adults should limit time spend outdoors and avoid
strenuous outdoor activities.
|
||||
Unhealthy
for Sensitive Groups
|
Members
of sensitive groups may experience health effects. The general public is not likely to be affected.
|
Everyone
should avoid prolonged exposure to smoke. Sensitive individuals such as those with heart or lung
disease, infants, children, pregnant women, or older adults should minimize
exposure by staying inside where air is cleaner.
|
||||
Unhealthy
|
Everyone
may begin to experience health effects.
These effects may be more serious for sensitive people.
|
Everyone
should limit time spent outdoors and choose non-strenuous indoor
activities. Sensitive
individuals such as those with heart or lung disease, infants, children,
pregnant women, or older adults should stay indoors where air is clean.
|
||||
Very Unhealthy
|
Triggers a health alert meaning everyone may experience more
serious health effects
|
Everyone should limit time spent outdoors and preferably stay
indoors where air is clean. Staying indoors is especially
important for sensitive individuals such as those with heart or lung disease,
infants, children, pregnant women, or older adults.
|
||||
Hazardous
|
Triggers health warnings of emergency conditions. Everyone is very likely to be
affected by serious health effects.
|
Everyone should avoid all outdoor activity. Relief from smoke is best
accomplished by leaving for cleaner air. Alternately, remain indoors where air is clean.
