Issued by NWS Pendleton OR
What:
For the Freezing Fog Advisory, visibility one quarter mile
or less in freezing fog. For the Air Stagnation Advisory, poor air
quality will continue. This is due to an inversion and stagnant
air conditions near the surface that will continue to trap
pollutants.
Where:
Central Oregon.
When:
For the Freezing Fog Advisory, until noon PST Saturday. For
the Air Stagnation Advisory, until 4 PM PST Tuesday.
Impacts:
Poor air quality may cause issues for people with
respiratory problems. Low visibility could make driving conditions
hazardous.
Instructions: An Air Stagnation Advisory indicates that due to limited movement of
an air mass across the advisory area, pollution has the potential to
increase to dangerous levels. Persons with respiratory illness
should follow their physicians advice for dealing with high levels
of air pollution during periods of stagnant air, state air quality
agencies highly recommend that no outdoor burning occur and that
residential wood burning devices be limited as much as possible.
According to state air quality agencies, prolonged periods of
stagnant air can hold pollutants close to the ground, where people
live and breathe. Check with your local burn agency for any current
restrictions in your area.
If driving, slow down, use your headlights, and leave plenty of
distance ahead of you.
