* WHAT...Stagnant air is expected, which may lead to
  deteriorating air quality.

* WHERE...Portions of northern California and south central and
  southwest Oregon, mostly in valley locations.

* WHEN...Until 4 AM PST Saturday.

* IMPACTS...Air stagnation can result in diminishing air quality,
  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.

* View the hazard area in detail at
  https://www.wrh.noaa.gov/map/?wfo=mfr

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.
