Spokane area smoke:
In the Spokane area, downwind of the Williams Flats fire on the Colville Reservation, smoke levels have been hovering in the Unhealthy-for-Sensitive-Groups to Unhealthy-for-everyone range for the couple of days.  Currently there is heavier smoke in the Green Bluff - Mount Spokane area.  For a lot of folks - mainly the elderly, children and anyone with heart or lung disease, this poses a health concern. Over 40% of the population falls into the Sensitive Groups category.  So even if you don’t mind the smoke, understand a lot of people are likely being affected. The longer air quality stays bad like this, the more people can be bothered. When the air quality is unhealthy for sensitive groups, people with heart or lung disease, children, people over 65, and pregnant women should limit outdoor exertion, and when the air quality gets worse than that, everyone should limit outdoor exertion. Anyone experiencing symptoms of heart or lung disease from smoke exposure should contact their health care provider. Visit WDOH’s Smoke from Fires for more on steps to reduce your exposure to smoke.

Eastern WA smoke pummeling the funneling point (Spokane) until Thursday

Eastern WA air quality and forecast
Spokane is the meeting point for smoke from eastern WA fires exiting the state. Several area monitors recorded Unhealthy air for some hours overnight. Here's what the satellite picture looked like just before sunset.

After dragging some smoke into the Columbia Basin this morning, winds will redirect it all at Spokane overnight today. Expect areas to reach Unhealthy for Sensitive Groups and Unhealthy at various times of the day Tuesday & Wednesday. In general, worse air at night and some relief during the afternoons. The National Weather Service in Spokane issued an Air Quality Alert to cover this situation.

Winds pick up late Friday but fire weather concerns also creep in by Saturday. Stay tuned.

Western WA
Light smoke from distant sources will add a wee bit of fine particle pollution to the urban mix, leading to a few Moderate hours in the Seattle area through about Wednesday evening. Barring impacts from localized fires, expect mostly Good air.

Ozone
Ozone is not released directly by sources but is formed when certain gases react together under the right weather conditions. Downwind of the Seattle- Tacoma metro area, ozone levels were Moderate yesterday and are expected to touch USG this evening. Kennewick might also see some Moderate levels Tuesday & perhaps Wednesday. More info on reducing ozone levels and protecting yourself can be found here.

Devore Creek Fire Smoke Outlook - Aug 5, 2019

8/4/2019 Here, there, and everywhere

There's a little smoke in the air throughout much of the state from a general mass that's floating in the atmosphere above us. A little smoke from Alaska, a little from Canada, and according to NASA scientists, much of the diffuse haze we're seeing throughout the state is traveling to us all the way from the huge fires burning in Russa.  More details at the link:

Outlines of smoke visible from satellite.

Closer to home we're also seeing air quality impacts in the eastern part of the state where areas downwind of the rapidly growing Williams Flats fire on the Colville Reservation are seeing smoke in the Moderate to Unhealthy for Sensitive Groups range this morning. Dispersion models indicate that smoke will move to the south and into the Columbia basin throughout the day which may lighten impacts in the Spokane area but cause smoke in Ritzville, Moses Lake and Kennewick before moving back toward the east toward Spokane again tomorrow. Williams Flats is reported as a grass fire. Grass fires can grow very rapidly but are often of short duration. Let's hope this one is brought under control in just a few days. There is also a new fire in the Idaho panhandle that is worth watching.

Devore Creek Fire - August 4, 2019 Smoke Update

Smoke Outlook for the Devore Creek Fire - August 3, 2019

Aug 2, 2019 - Smoke Outlook for the Left Hand Fire

8/1/2019 Smoke Outlook for South Central Washington

7/31/2019 Smoke Outlook for South Central Washington

7/30/2019 Air Quality and Wildfires Update

So far this summer wildfire smoke impacts to air quality have been fairly minimal. Significant smoke from numerous large wildfires in Alaska and Canada barely brushed the state by traveling instead to the east and the Great Lakes region. But a few active wildfires burning in Washington are causing light smoke impacts in the south central portion of the state. The largest is the Left Hand fire burning to the west/northwest of Yakima. Winds have moved the smoke from this fire to the south/southeast and the town of Sunnyside has seen multiple days of Moderate air quality conditions due to smoke from Left Hand and from the Pipeline fire. Other nearby communities from Ellensburg to Toppenish, Naches, and Yakima have experienced light smoke at times and are likely to continue to see smoke until the Left Hand fire is brought under control. Air quality impacts from Moderate to short periods of Unhealthy for Sensitive Groups can be expected in this area. Somewhat windy conditions today (Tuesday) could cause the Left Hand fire to grow. The nearby Pipeline fire is at 95 % containment with minimal fire behavior so should not contribute to degraded air quality much longer. See map below for location of these fires.

Left Hand.  31 mi NW of Yakima, WA. Start 7/23. Full Suppression. Cause: Lightning. 2,500 (+0) acres. 15% containment. Active fire behavior. Timber. Structures Threatened. Road and Area closures.  More details here: https://inciweb.nwcg.gov/incident/6456/
Pipeline.  7 mi N of Selah, WA. Start 7/23. Full Suppression. Cause: Unknown. 6,515 (+0) acres. 95% containment. Minimal fire behavior. Brush. Area closures. Transfer of command back to local unit will occur today.

Location of Left Hand and Pipeline fires.

Another fire to watch over time is Devore Creek located in extremely rugged terrain high in the Glacier Peak wilderness near the north end of Lake Chelan. Firefighters on the scene in Stehekin report that air quality there has remained good. Due to the remote location and extreme terrain, firefighters expect this fire will not be 100 percent extinguished until a season ending rain or snow event in the fall. Some visible light smoke is possible at times around the north end of Lake Chelan, Stehekin, and Holden Village but unless fire conditions change, air quality is expected to remain Good.

Devore Creek.  3 mi SW of Stehekin, WA. Start 7/26. Confine/Point Zone Protection. Cause: Unknown. 150 (+0) acres. 0% containment. Timber. Trail closures. More details here: https://inciweb.nwcg.gov/incident/6463/
