* what...degraded air quality due to poor mixing expected.

* where...valleys in central and eastern lake county. this 
  includes lakeview, summer lake, and valley falls.

* when...until 4 pm pst saturday.

* 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.

* 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.
