Air Stagnation Advisory issued January 9 at 2:33AM PST until January 11 at 10:00AM PST by NWS Medford OR
* WHAT...For the Freezing Fog Advisory, visibility one quarter mile
or less in freezing fog. For the Air Stagnation Advisory Within
the valleys in Douglas, Josephine and Jackson Counties, 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 Douglas County, Eastern Curry County and Josephine
County, and Jackson County.
* WHEN...For the Freezing Fog Advisory, until noon PST today. For
the Air Stagnation Advisory, from 10 AM this morning to 10 AM PST
Sunday.
* IMPACTS...Poor air quality may cause issues for people with
respiratory problems.
Most outdoor burning will likely be prohibited as poor ventilation
develops.
* ADDITIONAL DETAILS...A strong area of high pressure will build in
through Saturday, then weaken slightly on Sunday. This will lead
to poor mixing of the atmosphere and the trapping of pollutants.
The high is likely to strengthen again early next week.
Persons with respiratory illness should follow their physicians
advice for dealing with high levels of air pollution during periods
of stagnant air.
If driving, slow down, use your headlights, and leave plenty of
distance ahead of you.
