September 1 & 2, 2015
Dispersion and Air Quality Forecast
Dispersion is expected to be moderate the remainder of today and into 09/02/14. "Moderate" to "Unhealthy For Sensitive Groups" air quality is expected to remain throughout the period due to wildfire smoke impacting the area. It is important to note that while it may be OK to burn due to good dispersion conditions, many counties have burn closures as a result of current fire activity and critical risk of new fires igniting in all of Western Montana. The fire activity and associated smoke impacts we’ve experienced the past few weeks have been considerably great.
A cold front with gusty winds is expected to move into Montana on 09/2/15. In west-central/southwest Montana, these winds associated with the frontal passage will coincide with afternoon heating, allowing winds to mix to the surface which will provide for generally good dispersion in the afternoon of 9/2/15. Precipitation is expected to develop behind the cold front Wednesday evening into Thursday. During this period, dispersion conditions will be moderate in the morning and improve to good during the midday hours of 11am to 4pm due to good mixing conditions. Temperatures will be below normal throughout this period.
Open Burning Restrictions
Due to the uncertainty in fire behavior and the fact that we are seeing air quality impacts from smoke trending up, Montana DEQ has closed burning throughout Western Montana for the rest of 9/1/15 and into 9/2/15. Another update to this webpage will be made tomorrow afternoon for restrictions on 9/3/15.
Open burning in Cascade, Flathead, Missoula, and Yellowstone counties, and within the Libby Impact Zone, is at the discretion of the county air quality program. The contact information for these counties is provided below.

If you have submitted a written request and received permission with a burner identification number, please adhere to the instructions below. The Department will be working hard all winter to assess dispersion conditions and expected air quality in your area, and identify a timeframe that will minimize the impacts of your proposed burns to air quality.
- Please check this website often. It will be updated Monday through Friday, excluding holidays, by 5:00 pm. Burning “windows of opportunity” are infrequent and forecasts are subject to change.
- Determine if your assigned wintertime burn identification number is listed as having a possible “window of opportunity” on a given day. If so, call the Department's Open Burning Program Permitter Doug Kuenzli at 444-4267 at least 24 hours prior to the proposed date to create a burn plan. Please only call between 8:00 am-4:00 pm.
- Notify local fire control authorities prior to igniting your burn.
- At the completion of your burn, call the meteorologist to note the accomplishment achieved and indicate whether any future service will be required.
Thank you for working with the Air Resources Management Bureau to accomplish your burn.
