Washington Smoke Map

*The map above is not able to display all state air quality monitors. Click here to see all monitors in Washington: WA Ecology Air Monitors

Note: Some users might notice intermittent discrepancies in colors shown on the map of air quality monitors above, and those reported on the Department of Ecology's official page. This is because Ecology believes their method of calculating the air quality category (i.e. “Good”, “Moderate”, Unhealthy” etc) is more protective of public health in Washington. If in doubt as to which better represents public health risk, use the more stringent of the two (i.e. the map showing worse air quality).

Smoke forecast Friday 7/7- Monday 7/10

Currently air quality is mostly Good statewide, with a few Moderate areas sprinkled in. There are several brush fires burning and air quality is likely to be compromised closer to them.

Of immediate concern is the Red Flag Warning for much of eastern WA today. This graphic from the National Weather Service says it all:

A fair amount of fuels in WA are dry enough to burn, as indicated by the FPI index below (OK nothing like the desert southwest!)

While stronger winds will transport smoke from fires around the Cascade Foothills to parts of the Columbia Basin, fine particle pollution (PM2.5) is likely to be somewhat dispersed and I dont expect air quality to degrade much worse than Moderate later today. However as winds lighten over the weekend, communities such as Wenatchee, Quincy and Sunnyside could potentially see a few hours of Unhealthy for Sensitive Groups (USG) air, mostly at night and early morning. Expect mostly Good to Moderate air in other areas of eastern Washington.

No major storms or winds are expected over the next week. Temperatures are expected to remain close to or just above normal. Firefighting isnt going to be easy so lets do our best to prevent fires.
