* WHAT...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. For the
Freezing Fog Advisory, visibility one quarter mile or less in
freezing fog and possible locally slick conditions.

* WHERE...For the Air Stagnation Advisory, all low-lying areas in
Jackson and Josephine counties. For the Freezing Fog Advisory, the
Rogue, Applegate, and Illinois valleys in Jackson and Josephine
counties.

* WHEN...For the Air Stagnation Advisory, until 10 AM PST Sunday.
For the Freezing Fog Advisory, from 2 AM to 9 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
continues. Low visibility could make driving conditions hazardous.
Locally slick conditions are possible.

* ADDITIONAL DETAILS...A strong area of high pressure remains in
place. This will lead to poor mixing of the atmosphere and the
trapping of pollutants. The high weakens slightly on Sunday and is
likely to strengthen again early next week.

Information:
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.
