Smoke Forecast for Miller Complex -- Sept. 2, 2017

Smoke Outlook:  Miller Complex Issued for: Saturday, September 2, 2017

Air Resource Advisor: Willie Begay


Fire Activity:  Fire Behavior will increase rapidly if the inversion/smoke layer burns off. Fuel moisture conditions have changed enough that aspect and elevation are no longer holding up the fire spread. Spotting potential will be relatively high. Increase in wind speeds or direction can increase the fire behavior.

Smoke: The inversion/smoke layer will return today and will impact fire behavior. Smoky conditions of the fire will provide shading and the lack of air movement to withhold the increase in fire behavior.

*The Oregon Department of Environmental Quality has issued an Air Quality Alert in and around the outlook area and is in effect until further notice. Wildfires burning in the region combined with forecast conditions will cause air quality levels to fluctuate and could be at unhealthy levels.

  1. Could you explain if the the current AQI readings are what we can use to assess the air quality and safety or is the 24 hour data what is used? The forecast seem to go off the 24 hour data. What is the 24 hour data?
    Thanks.

    1. The one-hour average is meant to assess immediate exposure and the 24-hour average is meant to assess more long-term exposure at lower levels. Both can affect your health, particularly if you have heart disease, an ongoing lung condition including asthma, if you’re over age 65 or if you’re a small child.You can use these measurements for different purposes. For example, you can use the one-hour average to watch for periods of improved air quality, when you can open up your house and “air things out.” That way, you can start with cleaner air if heavy smoke returns. If you are sensitive to smoke effects and are deciding whether or not to work outside all day, you may want to use the 24-hour average, then use the one-hour average to pick the best time to go out for any unavoidable outside errands.

    2. Thank you so much! The blog is great. I have been using the one hour data to try and plan trips but I did not think about airing out the house.
