8/7/2018 Ways to protect yourself and your family from smoke

Wildfire smoke is in the air and parts of Washington state have been experiencing degraded air quality for days or weeks. The videos below share health advice and actions you can take to minimize your exposure to smoke and protect yourself and your family. The first is in English and the second is in Spanish.

8/7/2018 Public Notice and Air Quality Warning for Colville Reservation area

WA keeps accumulating smoke through Thursday

Puget Sounds Lowlands
Lots of social media pictures of pretty sunsets and crescent moon rises over western WA, courtesy of Oregon and California smoke. Adding to the mix is the Maple Fire, close to Hamma Hamma in the Olympic Peninsula- clearly seen sending a plume of smoke toward Seattle on yesterday's satellite picture.

Thus far most smoke has remained above or to the east of western WA but that seems to be changing. Between Tuesday & Thursday, the Puget Sound lowlands will likely see some combination of smoke from the fires mentioned above, and those along the Cascades' eastern foothills. Not much wind movement until late Thursday to flush things out, so expect conditions to mostly vary between Good and Unhealthy for Sensitive Groups. Some periods of Unhealthy air are likely closer to fires. Good air is expected Friday- Saturday.

Whatcom and Skagit counties
Periodic east winds could bring in smoke from fires in the North Cascades, causing Moderate and USG air on occasion. Higher terrain might also see some California/ Oregon smoke mixing down.

Eastern WA
Sadly, with so many fires and so little wind, Unhealthy air will be quite common in addition to the oppressive heat. No respite through Friday at least, but that smoke clearing comes at a cost: a strong front passing through will worsen fire danger and spread.

Smoke above western WA, smoke everywhere in eastern WA

Air monitors are showing Good air in western Washington for now. Enjoy it while it lasts. Webcams, satellites and upper air data show that smoke from fires in southern Oregon and N. California is already overhead.

Models show some of this reaching the surface, particularly higher terrain in the coming days and air quality could degrade to USG by mid-week.

The forecast is this work week is for hot temperatures and light winds so smoke will not be flushing out easily. If it is any consolation, the upper level smoke blanket will (1) make the heat a tad bit more bearable by shaving off a few degrees, and (2) make for pretty sunsets.

Sunday evening saw a bunch of lightning strikes in the Cascades and we don't yet know the full extent of the damage and where any additional smoke might flow.

Eastern Washington is being hammered by smoke from multiple sources, described in Friday's blog post below. The Methow valley's air has hardly been cleaner than USG all weekend, but that hasnt prevented everyone from taking in what can be seen of the scenery☺.

Assuming smoke production from these fires continues, expect conditions to worsen as the week proceeds. Areas close to fires could see Very Unhealthy air while other areas will vary between Moderate and Unhealthy.

Ozone levels are likely to be high around the Tri Cities Tuesday & Wednesday due to wind patterns, likely worsened a bit by the presence of smoke.

Take home message: it is shaping up to be a challenging week, smoke wise. Please take a moment to familiarize yourself with the health-protection resources on this blog. If you dont have an A/C that can be operated in recirculation mode when it is smoky outside, use an indoor fan instead of opening windows to cool down your home.

8/3/2018 Status of Wildfires in Washington

August 3, 2018

Two wildfires in Washington in particular - Cougar Creek and Gilbert/Crescent Mtn. are emitting significant amounts of smoke which is then combining with smoke from other fires in Washington and Canada to cause air quality problems for northern parts of the Columbia Basin from Chelan and Twisp, to Wellpinit and Colville. The Miriam fire near White Pass and the new Bannock Lakes fire in Glacier Peak Wilderness are worth watching in the coming days. More information on fires in Washington is shown below with links for even more detail when available.

Smoky Conditions Across NorthEast Washington

Smoke was clearly visible from local fires yesterday, not a good sign of things to come.

VIIRS Imagery from Thurday Afternoon

People across northern Washington, from Omak to the Spokane tribe, woke up to Unhealthy air quality this morning.   Air has even degraded to Very Unhealthy at times, due to smoke from multiple fires being carried east.  

  

PM2.5 Monitors - Friday Morning

Unfortunately, windy conditions will persist throughout the day, which will likely cause more fire growth and generate even more smoke.  The winds will have the benefit of momentarily clearing out smoke at times, but probably not for long.  The image below shows the path that smoke is expected to travel today, starting at the fire locations shown as red squares.  You can see how the area around the Spokane Tribe Reservation is being hit by multiple plumes!

HYSPLIT Forward Trajectory Forecasts from Fire Locations - Friday Morning

Winds are expected to die down over the weekend, as temperatures increase.  This means that smoke should disperse from Eastern Washington late today but people in North-Central Washington will likely see smoke persist locally around the large fires through the weekend and experience Unhealthy air quality at times.  It's only early August, so this could be just the beginning of persistent smoky conditions.

8/1/2018 Status of Wildfires in Washington

August 1, 2018

Most of the smoke impacts in Washington so far this year have originated from wildfires outside of the state but that is changing as a few local wildfires of some significance develop. One fire in particular is beginning to cause problems - the town of Chelan is experiencing air quality impacts from the Cougar Creek fire today and evacuations are in effect near Entiat. (More info. on Cougar Creek fire can be found here: https://www.fs.usda.gov/detail/okawen/news-events/?cid=FSEPRD589873 )

Important Note

The list of fires above and the map below comes from the local wildland fire Interagency Coordination Center (https://gacc.nifc.gov/nwcc/) which tracks large fires (100+ acres in timber or 300+ acres in grass/brush) and/or incidents with a Type 1 or 2 incident management team assigned. Small fires or new fires won’t show up on their list.

Smoke cleaning cycle in progress. Slow improvement in eastern WA

You've gotta see this in action!

Satellite picture around 10:30AM Tuesday shows smoke ahead of and clear conditions behind the well-defined northwest-southeast oriented frontal boundary over western WA.


Next satellite at about 1:30PM shows how the front pushed further east, clearing smoke in its wake.


Western WA has mostly Good air now, though a new fire on Harstine Island sent light smoke toward Tacoma last evening. This is not expected to continue much longer as crews are reportedly making good progress with this ~20 acre fire. Forecast for western WA is for mostly Good air through the weekend, barring new fires.

Forecast for eastern WA

Gradual clearing has already commenced, with more green dots (= Good air) appearing on the map. Wind speeds will ramp up Wednesday & Thursday, elevating fire growth concerns. Today's satellite pictures show smoke from fires in BC, Okanogan and Chelan Counties spilling lots of smoke into eastern WA. Stronger winds will dilute these somewhat, but some smoke is expected. Here's what the Forest Service's BlueSky smoke model is predicting for Friday (darker red = more smoke; a fire near the Methow Valley is not reflected in this).

Forecast is for mostly Good to air further from the fires through about Sunday, while locations closer to the fires shown above could see conditions deteriorate to Moderate or even USG levels. 

The atmosphere has started a self-clean cycle

Western Washingtonians awoke to cleaner air today as marine air started to displace accumulated smoke and usher in a cool-down. The Siberian, Californian and Oregonian smoke taps are being throttled down. All fine particle pollution monitors west of the Cascades have dropped down to Good levels this morning. North Bend still has Moderate air but is clearing out rapidly. This welcome cleaning cycle is poised to reach eastern WA by late today, but there is a caveat. Read on.

Yesterday's satellite picture overlaid with air quality data (Green= Good; Yellow= Moderate) shows smoke from various sources lingering over much of the state, giving rise to Moderate air in many places.

Forecast for western WA
The good news is that we don't expect a return to hazy skies within the next week, as long range forecasts indicate cooler-than-normal temperatures and the possibility of rain in western WA and the Cascades within the next 5-7 days. Yessss!

Eastern WA forecast
The weather pattern shift will indeed help flush out lingering smoke over the next two days, but the catch is that strong winds starting late tonight will enhance fire danger. Depending on fire growth, areas of USG air are possible over the next two days, particularly close to fires. Not expecting areas further from fires to deteriorate beyond Moderate between now and Thursday. Good news is that there wont be a return to hot and dry conditions; cooler temperatures late this week will aid firefighting efforts. Good air is looming on the horizon.

Light smoke over western Washington. It gets worse before it gets better

The light smoke blanketing much of eastern Washington has started to bleed west of the Cascades, further exacerbated by some fairly new fires in particular the Wrong Creek fire close to Mount Rainier. Tacoma, Puyallup and Auburn saw Moderate air on Saturday mostly due to the latter, and North Bend is currently experiencing Moderate air.

Here's the map of lightning over the last 24 hours. Thunderstorms in the Cascades on Saturday might have sparked off new fires but we don't have a handle on those yet. A red flag warning is in effect for the Cascades from now through 11PM on Monday, so fires will likely grow.

Expect a very hot, dry and relatively wind-less Sunday and Monday statewide. What this means for smoke Sunday and Monday:

King, Pierce and Snohomish Counties

Winds will be driven by terrain, meaning smoke will likely drain into communities along the Cascade foothills and perhaps closer to some of the larger cities overnight. Light amounts of that Siberian/ BC smoke overhead may mix to the surface during the day, more so at higher elevations. Expect Moderate air at times, though pockets of USG cannot be ruled out. Air should be mostly Good further west of the Cascades.

Most of eastern WA

Siberian smoke continues to cause Moderate/ USG air in much of eastern WA, with fires along the BC border, the Chelan Hills fire and other smaller fires also contributing. This is likely to continue through Tuesday, with any new fires adding more smoke to the mix. Some areas of Unhealthy air are possible.

When will it clear?

A wind shift and cool down happens in western WA on Tuesday, commencing a slow removal of smoke. Eastern WA has to wait until Wednesday. Winds are expected to be strong during the transition, raising fire growth concerns even as smoke flushes out.
