Central OR & JDICC Wildfire Air Quality Summary
Report

Air Quality Outlook
Yesterday saw
active fire behavior in both the South Fork Complex and Bald Sisters fires. Smoke lingered the nearby valley communities
including John Day, Dayville, and Prairie City. Seneca saw elevated concentrations early
morning through early afternoon with relief seen after the inversion broke.
Today more rain is
expected after noon. Gusty winds
associated with thunderstorms may increase fire behavior and test fire
perimeters. This may be tempered by
the likelihood of lower temperatures and higher humidity, serving to decrease fire activity. Smoke from both the South Fork Complex and
Bald Sisters fires will likely remain more localized and impact surrounding
communities much as it has over the last week. There is a slight chance that Burns may see
drift smoke from the South Fork Complex fire late tonight.
Tomorrow will see
smoke lingering in valley communities around the South Fork Complex and Bald
Sisters fires lifting with a break in the inversion late morning to early
afternoon. Cooler temperatures with
high humidity and rainfall from Tuesday are expected to reduce fire activity
such that smoke production will remain more localized. Gusty winds are expected to clear out the
smoke in John Day, Seneca, Unity, Paulina and surrounding communities and
return to better air quality conditions.

Potential Health Impacts
|
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.
