...air stagnation advisory now in effect until 10 am pst /11 am
mst/ tuesday...

* advisory...a ridge of high pressure will persist over eastern
  washington and north idaho through early tuesday. this will
  result in very light winds and poor atmospheric mixing. this
  will likely lead to increased pollution levels near the 
  ground and deteriorated air quality.

precautionary/preparedness actions...

an air stagnation advisory indicates that due to limited movement
of an airmass across the advisory area...pollution has the
potential to increase to dangerous levels. persons with
respiratory illness should follow their physicians advice for
dealing with high levels of air pollution.
