... Air quality alert in effect until further notice...
An air quality alert has been issued by the following agencies:
Washington department of ecology in Spokane
Idaho department of environmental quality in Lewiston

Elevated concentrations of wildfire smoke from area fires
continues across eastern Washington and north Idaho. Additionally,
blowing dust is expected over much of the area on Saturday. All
areas east of the Cascades and into north Idaho can continue to
expect poor air quality into the weekend. There may be times and
locations where the air quality improves to the good category, but
this is not expected to persist.
Precautions to be taken for areas experiencing increased smoke and
reduced air quality include:
*everyone should avoid heavy work or exercise outdoors when the
air quality index reaches unhealthy levels.
*Older adults, small children, and those with respiratory
conditions or heart disease may be more sensitive to poor air
quality and should stay indoors and avoid heavy work when air
quality reaches unhealthy levels.
*Drink plenty of water. Staying hydrated helps dilute phlegm in
the respiratory tract, making it easier to cough out smoke
particles. Plan on coughing; it is nature's way of clearing your
lungs. Avoid caffeine products, sugary drinks and alcohol because
they have dehydrating effects.
*Stay cool when the weather is warm. Run your air conditioner to
recirculate air. Turn The Fan blower on manually so it
continuously filters the air in your home.
*If working outside, use a dust mask... n95 or n100. If a dusk mask
is not available, cover your nose and mouth with a damp
This air quality alert will be reevaluated by Monday at noon.

result in rapid growth of existing fires or any new ignitions.
A red flag warning means that critical fire weather conditions
will develop today. The very strong winds coupled with the lower
relative humidity will create extreme fire growth potential.
