...AIR STAGNATION ADVISORY REMAINS IN EFFECT UNTIL 10 AM PST
THURSDAY...

* WHAT...Poor mixing and weak winds mean that stagnant air is
  expected, which may lead to deteriorating air quality.

* WHERE...Valleys of southern Oregon and northern California.

* WHEN...Until 10 AM PST Thursday.

* IMPACTS...Air stagnation is likely to result in diminishing
  air quality with time, especially in and near areas with
  significant sources of air pollution. Diminished air quality
  is likely to cause health issues for people with respiratory
  problems if precautions are not taken.

PRECAUTIONARY/PREPAREDNESS ACTIONS...

People with respiratory illness should follow their physician`s
advice for dealing with diminished air quality. N95 masks are
effective at filtering out the majority of harmful air
particulates.

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.
