Oregon State Smoke Forecast for Monday -Tuesday Sept. 4-5, 2017 (Revised)

Issued:  Monday Sept. 4 2017
Forecaster.  R. Graw, USDA Forest Service

A significant change has occurred since yesterday’s forecast, particularly for western Oregon, and to a lesser extent for Eastern Oregon, prompting an update to today’s forecast. Yesterday’s weather led to several new starts and significant growth on existing fires. Additionally, the winds overnight carried smoke from active fires in Oregon, Washington, and Idaho into several portions of the state including the Willamette Valley, the coast, and eastern Oregon. 

Monday, Sept. 4, 2017

A ridge of high pressure will remain over the state on Monday, as hot temperatures continue over the holiday weekend. This will cause a subsidence inversion and poor mixing of the atmosphere all day, keeping smoke trapped in the lower layers of the atmosphere.

Figure 1 illustrates the smoke pattern anticipated for today. For the western portion of the state, winds will be out of the east in the morning, then north in the afternoon. The coast and Willamette Valley will experience smoky and hazy skies, with the heaviest smoke in Eugene, Portland, and the Columbia River Gorge. Heavy smoke will continue to be present over southwest Oregon, and the central and southern Cascades. An east wind will bring some smoke into eastern Oregon from the fires in Idaho. Central Oregon will experience some of best air quality relative to other portions of the state.

Tuesday Sept. 5, 2017

 A subsidence inversion, combined with a thermal trough and east winds will create smoky conditions over Western Oregon on Tuesday, and light to moderate conditions over Central and Eastern Oregon, respectively.

Please refer to the Air Resource Advisor Reports on this blog for more detailed forecasts associated with individual fires. 
 
Disclaimer: Weather and fire activity can change quickly.  Please check back for updates to these forecasts as conditions change.  If you’re traveling out of Oregon, many other states also have smoke blogs, including California, Washington, and Idaho. So please consider those resources to help you plan your travels.

  1. Just got back to Shady Cove from Crescent City. While they are both extremely smokey, the smoke in Shady Cove seems to be a lot harsher on the lungs, eyes, and sinuses.

    Is it my imagination, or has this been the worst year for smoke in the region so far?

    1. Yes. Have friends who have lived here 50 years never seen anything like it.

    2. I am hearing that anecdotally for sure. I haven't seen the data for the season. Hang in there. I know the Rogue is really getting hit this summer.

  3. The governor should declare Oregon a state of emergency and ask the federal government for money and and as much help it will take to stop these fires. Complete idiocy and lack of leadership. Unacceptable.

    2. I agree 100 percent. It is a serious health hazard especially for the elderly and children. We obviously need assistance.

    3. For sure, they should have gotten to them when they first started...

    4. Uh, she did. On AUGUST 2. We have been in this hell for over a month. I sincerely hope that you have not voted to drown government services in a bathtub in the past and now express outrage at perceived government inaction. The fact is we are in a global state of emergency due to climate change. The truly scary thing is that the situation will only get worse.

    5. This is actually the fault of Environmentalits who helped to outlaw logging and thinning creating extra fuel for these fires to spread quickly and burn hotter. Native Americans knew this and did controlled burns long before all the ignorant environmentalists took over.

    6. That would help , an for Texas , Montana , an Washington ?

  4. You don't even show the Clatskanie area on your map....it is as though the top northwest corner doesn't even exist....but that is true because we have NO AIR QUALITY MONITORS UP HERE....I CAN'T SEE THE SUN FOR THE SMOKE....WELL RATHER I CAN SEE THE SUN...IT IS A DULL ORANGE BLOB IN THE SMOKE FILLED SKY....I'm inside and breathing is impacted...thank goodness I have air conditioning. Please be aware that Oregon does not end before you get the the Columbia River....And the east wind brings all the crap in the air down to the lower Columbia, whether smoke from forest fires or pollution from industry. AND NO MONITORING CAPTURES IT!!!! Grrrrrrrr

    1. Hi there, I know this doesn't help now, but I wanted to tell you that the Oregon Department of Environmental Quality is expanding the number of monitors it has next year. In the meantime, lots of folks are in areas without air quality monitors. Here's a way you can gauge conditions without a monitor: http://www.oregon.gov/deq/aq/Pages/Wildfires-Visibility.aspx Anyway, I know this isn't what you're looking for now and I get your frustration, but I wanted to make sure I let you know those two things.

    1. Thanks CP. Hang in there. I was in Roseburg two days ago and know it's smoky there!

  6. This is insane that Central Oregonians have been exposed to severely unhealthy -- according to DEQ -- air conditions for 3 weeks and no one..not even our Govenor... seems to give a damn. Many of us living hete have NO air conditioning and have been breathing severely unhealthy air for weeks. Amazing that the information that I read on how dangerous prolonged exposure to smoke is was posted on a website by the State of Oregon. WTF. Do something. The Milli Fire was allowed to burn without the Forest Service doing a thing. FYI: very savvy group organizing Class Action suit...gee Forest Service..better get to work. And stop blaming the hazardous air quality on fires in Idaho and Montana. We all know which direction the Jet Stream goes...

    1. There is not an unlimited number of wildland fire fighters. This fire season has been very long and hard. How about stopping your bitching and asking how you can help? Or are you concerned about breaking a nail?

    2. Remember too we are falling parallel and in the wake of Harvey (if we could only have some of their water) -- and certainly parallel to LA -- the entire West Coast is on fire -- the Governor as of 9/2 has declared a "state of emergency" -- I think the thing to do would be to bring it all to the attention of "the media" if nothing else --
      It seems the firefighters have done an AMAZING job containing the fires that exist and have erupted -- they continue tirelessly to protect our homes, communities and wonderlands -- pray for them, thank them, do what you can by you and know:
      heavy snow and hard winters bring bigger wildfires for all of the underbrush (fuel for the fires) fed by the water run off --- ... LIVE GREEN -- as GREEN as you can -- for our every step, individual and collaboratively, contributes to the outcomes. Peace.

    3. Sarah, there are people out there risking their lives for you, yes, ever since any fire near you got started. Please find more grace.

    5. Sarah,
      As a former 5 year employee of the Forest Service, they probably have everyone who can qualify including the office clerks out fighting the fire.
      If you think your air quality is bad try the air quality on the fire lline.
      Instead of trying to sue the government (almost impossible) Try Volunteering and helping out in the fire effort.

  7. Things are getting very tense as people can't breathe. Not a good feeling but at least I have air conditioning...I feel very bad for those who dont. Not sure what I can do to help.

  8. Thank you for these updates. Such great information.

  9. Let's ignore the sad, petty, selfish comments here about the state and think about the hundreds of firefighters out there busting their ass every day. This is mother nature, folks. If you want to complain, or sue someone, sue the lightning or your god. There are means for us to deal with the smoke. Come to terms with the fact that yes it is bad, and deal with it, rather than looking to big government to magically do something about it. And if you don't like it, please leave Oregon!

  12. The time and effort put into this Blog is unbelievable, the research, updates that someone has to call all over to get JUST IS MIND BLOWING. I had no idea we were in such bad shape. Our Air Quality has been 585 and I had no idea where it was coming from. THANK YOU for all you do.
