NWS: Air quality alert in effect for Spokane County and other WA counties until August 9

SPOKANE, Wash. — The National Weather Service has issued an air quality alert to remain in effect until August 9 at noon for multiple Washington counties.

According to the NWS, smoke from wildfires in Eastern Washington, British Columbia and Montana are expected to  impact air quality levels as winds push smoke in and out of the area.  Counties within the air quality alert are listed at the bottom of this page.

NWS said air quality will vary between good and unhealthy, depending on winds and time of day.

A measure of Spokane's air quality index was 187 Saturday morning, according to the Washington State Department of Ecology.

This number falls in the "unhealthy" category.  The WA State Department of Ecology says people should limit their time spent outdoors.

For a comparison, Beijing’s air quality index was 99 and Shanghai sat at 93.  These are considered moderate air quality levels, according to the World Air Quality Index Project.  

If the air quality level reaches above level 200, the category increases to "very unhealthy."  In this category, the WA State Department of Ecology recommends that people stay indoors.  If you have to go outdoors, approved masks are recommended.

 

The NWS said the following counties are under an air quality alert:

  • Adams
  • Asotin
  • Chelan
  • Douglas
  • Ferry
  • Garfield
  • Grant
  • Lincoln
  • Pend Oreille
  • Okanogan
