Welcome to the Washington Smoke blog, a partnership between state, county, and federal agencies, and Indian Tribes. We coordinate to collectively share info for Washington communities affected by wildfire smoke.
If the air monitoring map doesn't display here, links to additional monitoring maps can be found under the 'Monitoring & Forecasting' tab.
Well, mostly. Folks around
Leavenworth, the Puget Sound lowlands, and southeast Washington have been
breathing moderate amounts of smoke over the last day or two. There has been some prescribed
burning approved recently and a wildfire outside of Leavenworth which may be
contributing locally to the higher smoke values, but most of the smoke seems to
be drifting in from Oregon and Idaho.
East winds helped drag some
smoke from Idaho across the Palouse and the Lewis- Clark Valley. In western
Washington, south winds brought in some smoke from wildfires near Mount Hood in
Oregon. In most cases, air quality degraded to "Moderate".
Here is the satellite image over Washington, taken on Monday morning. Notice the Idahoan smoke coming down the Clearwater river valley. South winds picked up later in the day and brought in more smoke from Oregon. In addition there are areas of smoke in central and western Washington, partly caused by prescribed burns.
The picture is likely to remain
the same through this evening, after which winds turn a bit more westerly, and
become southwesterly by Wednesday. Western Washington will see less Oregon
smoke starting Wednesday morning. But
southwest winds mean smoke from Oregon is likely to impact cities in a line
from The Dalles, OR through Spokane, at least through Thursday.
will see some relief from Idahoan plumes before Oregonian plumes show up. Air
quality is likely to hover between Moderate and Unhealthy for Sensitive Groups.
Stronger winds are expected on
Thursday and this is likely to disperse smoke more. Things calm down as a ridge
builds from Friday through the weekend bringing us nice weather statewide and
also poor smoke dispersion. We are not likely to see a lot of smoke from
neighboring states transported over Washington, but cities closer to the fires
will be impacted. Some daytime clearing is expected.
In addition, smoke from various
prescribed burns could bring some smoke to different parts of the
state. Forecast will be updated as needed
