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 in western Washington today
Smoke from fires in the Olympic National Park south of Port Angeles drifted over the Seattle/ Tacoma/ Olympia area from Friday evening, but will dissipate during the day today. Forecast suggests air quality should be no worse than Moderate over the Seattle area at nighttime with clearing both east and west of the Cascades during the daytime over the next few days.
The above mentioned fires were ignited by lightning about a month ago and were smoldering lightly until recent hot weather energized them. Fire weather concerns remain through Sunday and Monday, west and east of the Cascades respectively.
