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).

The good news is that winds are picking up across the state and eastern Washington will continue to see improving air quality through the rest of the day. Some hard-hit areas in the Columbia basin are now reporting good air quality. Winds are likely to remain moderate to strong in eastern Washington through Wednesday, so smoke is unlikely to build up. The caveats are that strong winds could boost fire activity (The National Weather Service issued a Red Flag Warning through Tuesday night), and limit how high smoke plumes rise.
Air quality is expected to range between Good and Moderate in areas away from the fires. In general, better air during the daytime, slightly worse at night. Closer to the fires, air is likely to vary from Moderate to Unhealthy at times.
There is also a Twitter Feed for this fire #WolverineCreekFire https://twitter.com/hashtag/WolverineCreekFire?src=hash
An air monitor has been set up in Chelan by the Emergency Management Team and they are posting updates in the comments section on Air Quality conditions with health messaging from the local health district.

Since wildfires often occur in remote areas, air monitoring equipment may not be available. The following table provides a quick method to assess air quality in your area. For more detailed information you can go to the following site:http://www.deq.state.or.us/aq/burning/wildfires/visibility.htm

*No matter how far you can see, if you feel like you are having health effects from smoke exposure, take extra care to stay inside or get to an area with better air quality. You should also see your doctor or other health professional as needed.

5 pm Sunday with possibly some scattered mid-level clouds Sunday
By Monday some cooling and increased winds--still an adiabatic sounding up
through 700 hPa (about 10,000 feet) with scattered to broken mid-level clouds.
By Tuesday evening the skies will again be clear and then slight warming
through next weekend.
Throughout the period there will be good vertical mixing to:
1. Mix any smoke lofted by the heat of the fire down to the ground, and
2. Dilute that same smoke through a deep layer and decrease the ground level
concentration from what an undiluted plume would produce.
Also throughout the period there will be moderate winds on most afternoons to
also help dilute the smoke.
Unfortunately, the wind, vigorous vertical mixing, and warm to hot temperatures
with low relative humidities are also favorable for fire growth leading to
increased smoke production. The balance is expected to produce smoky skies
with limited visibilities in areas near the fire. Methow and Chelan valley
ground level concentrations could reach the Unhealthy for Sensitive Persons at
Fire crews are expected to begin doing some burning to keep the fire away from
Holden by early next week. That will likely produce a surge of smoke
but should limit the long term impact from this fire.
The good news is that the nearest precip stays up in central BC--good because I
don't want any chance of convection (lightning) until we can get a heavy dose
of moisture (precipitation) in here--where is a western Pacific typhoon or
eastern Pacific hurricane when you could use one?
