New incidents continue to emerge and active fires continue to grow. The Lynx Mountain Fire northwest of Inchelium is adding to the mix of fires in Northeast WA. In Central WA, The Lower Sugarloaf Fire 12 miles northeast of Leavenworth grew quickly overnight and is sending smoke to the southeast.

In the Cascades near Mount Rainier, the Wildcat Fire is currently estimated at 1,279 acres and 0% contained. Continue to keep an eye on daily smoke outlooks for the fire for local smoke impacts and fire information. Further north, the Perry and Martin Fires in the northern and central Cascades are producing localized smoke.

In Western WA, the hot and dry weather contributed to slight growth of the Bear Gulch Fire (currently 9,400 acres). The fire is expected to remain active and produce local smoke impacts in the Lake Cushman/Hoodsport areas.

Increasing Smoke Impacts

Smoke will increase throughout the day today; most of Central and Eastern Washington should expect air quality impacts ranging from Unhealthy for Sensitive Groups to Very Unhealthy as the smoke mixes down to the surface. Light and variable winds will do little to disperse the smoke, allowing PM2.5 to accumulate. In addition to smoke from fires in Washington, smoke from wildfires in Southern British Columbia will drift south into Okanogan and Chelan Counties. We're also monitoring other regional fires (i.e., the Ulm Creek Fire in Idaho) that could add to smoke impacts in the coming days. 

In Western WA, smoke impacts will be mostly minimal at the surface--but haze will be visible as smoke drifts aloft.

Air Quality Alerts have been expanded to include all counties in Central and Eastern WA. 

When will conditions improve?

Unfortunately, relief from the smoke in Central and Eastern WA won't arrive for at least a few days. Hot, dry, and unstable conditions will continue through Friday. In addition to poor smoke dispersion, dry thunderstorms will increase the potential for lightning and new fires--and these new fires will likely grow quickly. Fire weather concerns begin to ease on Friday, but the heat will persist and it could take time for the smoke to mix out. We'll update as needed as smoke continues and new fires emerge--keep an eye on the map at the top of this page for current and forecasted air quality conditions.

-----------------------------------------------------------------------------------------------------------------------------

As an aside, if it feels like early September often brings smoky skies, you're right. Fire season remains active this time of year, and since 2012, Washington has frequently experienced smoke well into September. The plot below shows the statewide summer daily averages from all monitoring sites in the state, with 2025 highlighted in bold black against the gray lines of 2012-2024.

Air Quality Alerts and Heat Warnings in Eastern Washington

Wildfires Increasing and Growing

Lightning has ignited numerous wildfires across central and eastern Washington in the past week including incidents that are still emerging after dry thunderstorms over the weekend. 

In northeastern Washington, the Crown Creek Fire has rapidly grown to 3,193 acres and the Rattlesnake Fire has grown to 1,887 acres. There are also smaller but growing fires in that area including Katy Creek and Tacoma Creek Fires. All of these fires are 0% contained and producing significant smoke.

Fire activity has also increased in the Cascades, especially along and just east of the Cascade Crest. The largest new fire in that area is the 1,170 acre Wildcat Fire burning near Bumping Lake in Yakima County, east of Mount Rainier National Park. The park remains open to the public, but further east, the Pacific Crest Trail is now closed between White Pass and Chinook Pass. For those living and recreating near Mount Rainier, daily smoke outlooks are now being produced for the Wildcat Fire by an Air Resource Advisor. These forecasts offer visitors guidance around finding a less smoky area or favored time of day that might minimize smoke exposure. The 737 acre Perry Fire, 122 acre Martin Fire, and numerous emerging incidents are also producing localized smoke impacts in the central and northern Cascades.

Lastly, the 9,388 acre Bear Gulch Fire continues to burn in western Washington on the Olympic Peninsula, west of Lake Cushman. It is 10% contained and burning in steep, rugged terrain. 

Smoke Impacts Building in Central/Eastern Washington

As of Tuesday afternoon, smoke is mainly concentrated in the Cascades and across eastern Washington. The larger population centers on the east side of the state such as Wenatchee, the Tri-Cities, and Spokane are generally experiencing MODERATE air quality. However, smaller communities closer to the current fires are experiencing air quality ranging from UNHEALTHY FOR SENSITIVE GROUPS to VERY UNHEALTHY – this includes places like Colville where the AQI has rapidly spiked today. Smoke has also been drifting into places like Moses Lake this afternoon. For a full picture of current air quality you can always view the map at the top of this page. Air quality alerts are now in effect until further notice for Spokane, Lincoln, Stevens, Grant, Kittitas, and Yakima Counties.

As high pressure sits over the state and new fires emerge and potentially grow this week, smoke will likely continue across eastern Washington and through the Cascades. Day to day smoke concentrations will vary depending on wind direction, but full clearing of the smoke seems unlikely through at least Friday. West of the Cascades, smoke concentrations will be less – but may still be visible at upper levels of the atmosphere. Some of the smoke moving overhead will also be coming from distant fires in Oregon, especially the Emigrant Fire.

Heat and Smoke Combine - How to Protect Yourself

In addition to smoke, much of eastern Washington is under Heat Advisories or Extreme Heat Warnings. Temperature records are being challenged for this time of year, though it remains to be seen whether smoke will have a slight cooling effect that keeps us from breaking those records. 

NWS Heat Risk for Wednesday, September 3.

Smoke and heat combined can present unique challenges. Heat is the more immediately dangerous threat. If it's hot indoors during poor air quality, these steps can help you stay cool:

• Close windows, curtains, and shades during the day and use portable fans.
• Minimize your use of the stove and oven during the hottest parts of the day.
• Take a cool bath or shower. Be mindful of extreme temperature changes, which can cause life-threatening issues.
• Use ice packs or put your feet in cool water. Apply wet rags on the back of your neck or mist yourself with water while sitting near a fan.
• Stay hydrated, especially with water. Avoid sugary or alcoholic drinks since these can be dehydrating.
• Go to a cooler indoor place – even if only for a few hours. For updated information on cooling centers in your community, visit Washington 2-1-1.
• Only open windows when it is cooler outside than inside. An open window is most effective when a door or additional window can be opened to provide a cross draft. For more information, see Cooling Indoor Spaces Without Air Conditioning (PDF). 
• Take steps to filter indoor air (See “How can I improve filtration in my home to reduce smoke levels?”).
• Check on your neighbors and others in your community who may not have access to cooling.

For more on protecting yourself from smoke and extreme heat, see the Department of Health 'Smoke From Fires' webpage.

Additional blog updates will be posted as conditions warrant this week and beyond. Stay cool out there!

New Fires This Weekend

Several new fires have grown this weekend, many of which were caused by lightning on Friday night.  

Crews are working hard to contain fire growth, but the Crown Creek fire near Colville has been especially problematic.  Currently air quality is unhealthy in the Colville region. Low mixing heights are containing smoke near the surface, and unfortunately the light wind flow and hot temperatures in Northeast Washington are expected to continue for the coming days.  The Katy Creek fire is also adding to the mix.

The map below shows the most significant fires in the state right now, causing smoke in their areas.  The Perry and Wildcat fires are impacting air quality in the Cascade mountains, while the Bear Gulch fire continues to impact the area around Lake Cushman.

If you live around south-central Washington, don't be surprised if the Emigrant fire in Oregon causes some moderate haze in the coming days, as satellite imagery shows a significant plume.  

Smoke Expected to Continue.

Fire and Smoke Map 8/29/2025

Smoke in Washington has been largely due to smoke from other fires outside of the state. The highest levels of poor air quality locally, remains closest to current fires.

WA DNR's Wildfire Dashboard

Currently in Washington, there are 4 major fires.  The current concerns are of scattered thunderstorms. Going into Monday, we enter a significant, possibly record-setting heat wave – especially for the eastern half of the state. Temperatures in eastern Washington will be in the 95 to 105 degree range each day Monday through Thursday. 

Western Washington will also feel a heatwave starting Wednesday of next week next week, peaking Thursday or Friday with temperatures in the upper 80s to mid 90s, potentially nearing 100 in portions of far SW WA and the Columbia Gorge.

With heightened temperatures and dried fuels, concerns remain for new fire starts. Forecasters will keep an eye on weather changes and new fire starts. 

Statewide smoke update: heat and lingering impacts

Over the weekend, smoke drifting in from fires in Central Idaho led to significant smoke impacts in Southeast Washington. 

Yesterday's satellite imagery showcased the smoke from Idaho impacting Southeast Washington. Smoke from the Bear Gulch Fire is also visible, as well as a new fire in British Columbia.

Monitoring sites in Clarkston and Pullman observed some of the highest PM2.5 concentrations of the season:

Hourly PM2.5 concentrations from monitoring sites in Clarkston and Pullman. Data accessed 11am 8/25/2025.

Hot weather combined with increased regional fire activity continues to produce widespread haze and moderate air quality across much of the state. The heat will continue into Wednesday morning. Smoke impacts in Southeast WA will continue through at least mid-week, although likely less impactful than the weekend's smoke due to shifting winds. Air quality will likely remain moderate with periods of USG. There may be occasional Unhealthy air quality in the Clarkston area. Lingering haze could extend as far north as Spokane. 

The Bear Gulch Fire remains active. The greatest smoke impacts will continue to be closest to the fire near Lake Cushman. Haze will be visible throughout the region.

Moderate air quality was observed yesterday in western WA and continues into today. While smoke from the Bear Gulch Fire is contributing to slightly degraded air quality, heat and stagnant meteorological conditions are also trapping pollutants at the surface. Light winds are limiting dispersion, allowing pollution to accumulate. It's likely that the PM2.5 currently measured at monitoring sites reflects both wildfire smoke and Secondary Organic Aerosol (SOA). SOA forms in the atmosphere when volatile organic compounds (VOC) emitted from vehicles, industrial processes, and trees and plants react with oxidants in the atmosphere, including ozone. Hot weather enhances ozone formation and increases the biogenic (trees and plants) fraction of VOC emissions.  Over the weekend, elevated ozone concentrations were observed along the Cascade Foothills of King and Pierce counties; similar conditions are expected today and tomorrow.

Critical fire conditions are expected today and tomorrow in the Cascades and Methow Valley. The heat will begin to ease on Wednesday; cooler temperatures may reduce fire behavior and lessen smoke impacts. However, smoke and haze may linger through the week. If new fires start, smoke impacts could increase. Keep an eye on current and forecasted conditions on the map at the top of this page, and we'll provide updates as needed.

Hot, Dry Weekend Ahead with Smoke Impacts Possible

A heatwave is approaching Washington, with temperatures reaching the upper 80s in western Washington and the upper 80s to upper 90s in eastern Washington tomorrow afternoon. This stretch of hot weather is expected to last through the weekend and into early next week. Highs this weekend will climb into the low 90s in western Washington and could reach the low 100s in the Columbia Basin. Along with the heat, low relative humidity is expected across the state.

Peak Temperatures this Saturday (8/23) at 5pm

Moderate heat risks in western Washington this weekend will mainly impact those most sensitive to heat, particularly people without access to cooling or adequate hydration. In central Washington, major heat risks are expected, posing a danger to everyone without access to cooling and hydration.

Heat Risk Forecast for this Saturday, courtesy of  NWS HeatRisk Graphics

These hotter, drier conditions will likely increase fire activity on the Bear Gulch Fire, with potential smoke impacts for Lake Cushman and surrounding areas.

The Island Creek Fire in central Idaho and the Sunset Fire in northern Idaho are other sources of concern for smoke. As winds shift this weekend—from the typical onshore flow to an easterly direction—smoke from the Island Creek fire could move into southeast Washington. If the hot and dry conditions promote more activity from the Sunset fire, then there could be potential for smoke in other parts eastern Washington, although this remains uncertain.

For those experiencing smoke during this heatwave and without air conditioning, there are steps you can take to stay cooler while keeping your indoor air clean. These include closing windows, curtains, and shades; minimizing stove use during the hottest parts of the day; taking cold showers or baths; and staying hydrated. For more information on protecting yourself from smoke, visit the Washington State Department of Health’s Smoke from Fires page.

We’ll continue to monitor smoke from the Island Creek Fire and post updates here as conditions change.

Wednesday Smoke Recap and New Fires

Wednesday Smoke Recap

It was an interesting air quality scenario on Wednesday as smoke from the Bear Gulch Fire crossed the Cascades Tuesday night and settled over the Columbia Basin Wednesday morning.

In a "normal scenario," smoke trapped beneath an inversion layer will disperse and air quality will improve as the inversion breaks. But on Wednesday, smoke was trapped just above the morning surface inversion. As the inversion broke, the substantial smoke plume began to mix both up and down, and air quality began to deteriorate during the late morning hours. Air quality was mostly Moderate or Unhealthy for Sensitive Groups, though a few monitors and sensors did record a brief period of Unhealthy air.

The reduced fire activity at Bear Gulch has resulted in less smoke over eastern Washington Thursday morning, though there was some smoke trapped underneath the morning inversion. With less smoke overhead, we're seeing a more "normal" scenario play out and air quality is improving as the inversion breaks.

Two New Wildfires
With hot, dry, and windy conditions developing Wednesday afternoon, two new large incidents emerged. The Central Ferry Fire in southwest Whitman County grew to approximately 6,000 acres and remains 0% contained. Smoke impacts are confined to the immediate area surrounding the fire, particularly along the Snake River.

In Lincoln County, the Crescent Road Fire is burning just south of the Spokane River and crossed into far northwest Spokane County Wednesday night. It's currently 779 acres and 0% contained. Fire activity has begun to increase late Thursday morning, and air quality near and just north of the fire will likely range from MODERATE to UNHEALTHY, especially along SR-231 and SR-291.

Fire danger decreases Friday into the weekend with widespread rainfall in and west of the Cascades. Increased relative humidity and scattered showers east of the Cascades will reduce smoke output from new and existing fires, and air quality is expected to improve.

Smoke on the Move

This morning's satellite image showcases two impressive narrow bands of smoke moving across the state:

GOES-WEST satellite image 13 Aug 2025 15:36Z

The northernmost plume is smoke from the Mount Underwood Fire on Vancouver Island, while smoke from the Bear Gulch Fire is drifting across the middle of the state. 

This morning, a fascinating wave-like pattern formed as smoke from the Bear Gulch Fire drifted above Snoqualmie Pass:

A large pyrocumulus cloud was also visible above the Bear Gulch Fire. These "fire clouds" form over large heat sources due to intense upward vertical motion of air cooling and condensing as it rises.

Although most of the smoke is above us in the atmosphere, it's currently contributing to moderate air quality in Central Washington and hazy skies throughout the state. Winds should continue pushing the smoke to the east today. 

Rain remains in the forecast, arriving in Western Washington Thursday evening before spreading east through Saturday--great news for dampening fire activity and reducing smoke impacts across the state.

What’s in the Air Today

Heavy smoke from the Bear Gulch Fire is creating HAZARDOUS air quality around Lake Cushman this morning, with smoke drifting south into Hoodsport. As a result, an Air Quality Alert has been issued for Mason County, effective until 9 AM Friday August 15 due to the smoke from Bear Gulch fire.  For current smoke conditions and forecasts in the Bear Gulch area, check the Smoke Outlook.

Elsewhere, air quality is MODERATE to the east of Bear Gulch, including the Kitsap Peninsula and Shelton. Some smoke may drift into the southern Puget Lowlands today, mixing with higher ozone concentrations due increased temperatures, but overall air quality should remain moderate. Along the coast today near Taholah, air quality is also MODERATE but should improve as concentrations drop through the day.

A new wildfire started Monday near Port Alberni on Vancouver Island. It has grown quickly over the past 24 hours and is now at 1,556 acres. Smoke from this fire has been moving down along the Washington coast but is currently staying offshore. As more smoke is produced and winds shift from the northwest later today, smoke will be visible through most of western Washington this evening. However, most of this smoke is expected to remain high in the atmosphere and should not affect air quality at the surface. Check the surface quality map above this post to see what the AQI is near your location.

Later This Week – A Wet Turn for August

Looking toward the end of the week, we’re seeing an unusual trend for August: rain, and plenty of it. Areas around Puget Sound could see up to 1 inch, with the Olympics and Cascades possibly picking up as much as 2 inches. Eastern Washington will have a shot at some rainfall as well, though amounts will be lighter than on the west side. This wet system should help slow ongoing fire activity and reduce the risk of new starts, with minimal smoke impacts expected across the region.

Weekend Update - Bear Gulch still going strong and warmer weather this weekend

Washington saw a shift to cooler, cloudier conditions this week as a cold front ushered in a notable rain event. The change offered some reprieve from drought and fire activity.  However, over the next few days Washington will see a shift toward hotter, drier conditions that elevate fire weather concerns. 

In western Washington, ridging from the northeastern Pacific will bring a warming and drying trend through early next week, with highs in the 80s by Sunday and Monday. Overnight humidity recoveries will remain good in the near term, but fire danger will increase late this weekend. Eastern Washington will experience even hotter conditions, with widespread 90s and some locations—such as Omak, Wenatchee, Moses Lake, and Lewiston—approaching 100°F on Monday. 

The Bear Gulch fire in Mason County continues to show active behavior, which will likely increase through the weekend.  Satellite imagery shows the Bear Gulch as the only source of visible smoke right now in the State.  Residents in the area (e.g. Hoodsport) should continue to expect poor air quality late at night and in the mornings.  However, daily clearing should occur as it gets warmer and smoke lofts higher in the atmosphere.  Moderate air quality in the greater Puget Sound region may occur throughout the weekend as the Bear Gulch fire grows.  For more a detailed forecast about the Bear Gulch fire, see the Smoke Outlook.

Residents in Eastern Washington are currently experiencing Good air quality, but it wouldn't be surprising if moderate smoke is generated on hot days as fires increase their activity. Winds east of the Cascades will strengthen early next week, but there is an expected cooling trend midweek.

National Weather Service Infographic for Friday, August 8.

The Bear Gulch Fire, Smoke in the Puget Sound, and best of all, Rain in the Forecast

Many folks in Puget Sound smelled and saw smoke from the Bear Gulch Fire Friday afternoon, Sunday night and even a little this Monday morning. While some areas experienced elevated smoke for a few hours Sunday night, the smoke didn't hang around long enough that AQI NOWcast exceeded moderate (yellow) conditions. Most air monitors and sensors around Puget Sound returned to an AQI reading good (green) this morning, but have since gone back to moderate. With the exception of those communities closest to the fire, we do not expect air quality around the Puget Sound to get worse than moderate over the next few days, and will likely continue to vary between good and moderate. Sensors in the Cascades also report moderate air quality from smoke lingering at upper elevations. The following plot shows smoke yesterday afternoon and evening between 1 and 3 km elevation over Tacoma.

Cooler temperatures and high relative humidity over the next few days will hopefully keep fire activity to a minimum, but we're really all looking at Wednesday. Forecasts predict a front moving through early Wednesday morning bringing showers throughout the day across all Western Washington, with potential for 0.3 to 1" precipitation around Cushman. It will likely not be enough to put the fire out altogether, but will be a huge help to our fire fighters and in clearing smoke from the air. Forecasts for this weekend and next week will be addressed in a post later this week.

Probability of total rainfall exceeding 0.5" for Wednesday, August 6th

Smoke Update: Bear Gulch and New Fires in Central and Eastern WA

In the Olympics, the Bear Gulch Fire grew rapidly over the past couple of days to 3,900 acres. The fire will continue to actively burn, but compared to the unhealthy air quality earlier this week smoke impacts should be much more moderate due to cooler and wetter weather. However, communities closest to the fire will continue to experience the greatest smoke impacts. At higher elevations in the Olympics, smoke may adversely affect hikers, campers, and park visitors. Nearby, the Hamma Fire is 80% contained; smoke impacts from that fire will be minimal. Hazy skies will continue to be visible in the region.

Note also that there is a smoke outlook for the Bear Gulch Fire area that is updated daily--click the box around the fire at the map at the top of this page for the most recent outlook.

Bear Gulch fire perimeter and closure map. 

A few new fires began yesterday in Central and Eastern WA, likely sparked by lightning. The Stud Horse Fire (2 miles east of Winthrop) is currently causing smoke impacts in the Winthrop and Twisp area. The Siwash Fire (east of Tonasket), Kinkaid Creek Fire (8 miles north of Nespelem), and Kaiser Canyon Fire (3 miles south of Nespelem) are also causing local smoke impacts. Communities closest to these new fires will observe periods of degraded air quality (moderate to USG) depending on fire behavior.

Good news: other fires in the state are exhibiting minimal fire activity and generating minimal smoke impacts.

Outlook: There is a risk of thunderstorms and gusty winds in Eastern WA today, which could ignite new wildfires and lead to rapid spread. Looking ahead to the middle of next week, there is the potential for rain in Western WA, although how much rain is still an open question. Unfortunately hot and dry conditions statewide will likely return next weekend. For now--and over the next few days--air quality will be mostly good across the state, except near active fires.

Warm and Dry Summer Contributes to Wildfires on the Olympic Peninsula

Purple air sensors near Lake Cushman currently report hazardous air quality due to the Bear Gulch Fire. Vertical mixing and dispersion should improve air quality in the area throughout the day. That said, warm and dry conditions could increase fire activity and cause air quality to degrade later this evening. The fire is burning in steep terrain, causing challenges for firefighting efforts. Firefighting crews are currently protecting the Staircase Area and other nearby park structures. The Bear Gulch Fire will likely burn for several weeks until the area receives significant precipitation, causing intermittent smoke impacts for the foreseeable future.

Nearby fires are also contributing smoke in the Lake Cushman/Hoodsport Area. The Hamma Fire (about 2.5 miles northwest of Eldon) began on July 27th and the Browns Creek Fire south of Lake Cushman started yesterday afternoon and has burned about 12 acres.

The South Huckleberry Fire, west of Lake Quinault, was reported this morning at about 15 acres with a smoke plume visible on satellite imagery.

Highlighted circle shows smoke plumes from the South Huckleberry, Hamma, Browns Creek, and Bear Gulch Fires. GOES-WEST 29 JUL 2025 17:16Z

Communities near these active fires will observe the greatest smoke impacts overnight and into the morning hours before smoke disperses during the day. Kitsap County may also experience periods of moderate air quality. Outside of these areas, surface air quality should continue to be mostly good in Western Washington, although upper-level haze will be visible throughout the region.

As for the rest of the state, recent air quality has generally been good throughout Central and Eastern WA. Containment has increased for the larger fires; the Burdoin, Hope, and Lake Spokane fires have not grown significantly and continue to show little activity. The Pomas Fire continues to burn near Entiat with minimal smoke impacts. 

Continued hot and dry conditions statewide could increase smoke production from active fires in coming days. Thunderstorms Wednesday through Friday bring the potential for new fire starts with the greatest risk Wednesday with dry thunderstorms over the Cascades.

Update: July 30, 3:30 PM Smoke from the Bear Gulch Fire is impacting most of Mason County and causing unhealthy air quality throughout the region. This was unexpected based on forecast winds, but when smoke is thick enough it can stabilize the atmosphere and change the local weather. We don't yet know how long the smoke will last or how far from the source it will spread. All residents in Mason County should limit their outdoor exposure this evening. Residents in North Thurston and south Kitsap may also see some smoke impacts. We'll keep you updated as we get more information.

A Short but Welcome Reprieve from Hot, Dry Conditions

 

Fire Updates

While the weekend remained hot and windy, two notable wildfires ignited: the Lake Spokane Fire (located Northwest of Spokane) and the Burdoin Fire (located about 2.5 miles east of White Salmon, WA, along the Columbia River).

View of Burdoin Fire from Oregon. Image courtesy Burdoin Fire Facebook. 

The Lake Spokane Fire is currently burning 1,751 acres and is 1% contained. The Burdoin Fire has rapidly expanded to 10,730 acres since its ignition Friday afternoon, fueled by strong winds gusting through the Columbia River Gorge on Friday and Saturday. It remains at 0% containment.

Air Quality Overview

Air quality is currently GOOD across Western Washington, thanks to a low-pressure system that moved in over the weekend, clearing out much of the hazy air. In Eastern Washington, MODERATE air quality has been reported across the Columbia Basin due to smoke from the Burdoin fire. Areas near the Lake Spokane fire have experienced air quality rising to UNHEALTHY just this afternoon. If you're in areas with elevated smoke levels, it's best to stay indoors, limit strenuous outdoor activity, and keep windows closed to reduce exposure.

Weather Outlook

Today and tomorrow bring a short reprieve from critical fire weather as cooler temperatures settle in. The low-pressure system will move slowly across the state, bringing cooler conditions, scattered rain showers, and low winds, a welcome break in what has been a hot, active fire season. Starting Wednesday, Eastern Washington will return to very warm and dry conditions. Winds will increase by Thursday, setting up a period of hot, dry, and windy weather, ideal conditions for new wildfire starts. Smoke impacts could increase by the end of the week, so keep an eye on local air quality conditions.

Fire Containment Update

There is some good news: the Hope and Pomas Fires are now producing significantly less smoke, and the Western Pines Fire is 100% contained!

As always, check the air quality map at the top of this page for the most up-to-date conditions and stay smoke-aware.

Onshore Winds and Cooler Temps this Weekend

Fire activity has continued across Washington this week. On the west side of the state, the Bear Gulch Fire continues to burn near the Staircase entrance to Olympic National Park. The fire is 562 acres and 19% contained. Hot and dry weather led to increased fire activity this week, but cooler weather is on the way (more on that later).

The Bear Gulch Fire burning in steep terrain above Lake Cushman on Wednesday, July 16.

Fires also continue east of the Cascades. The Pomas Fire is 3521 acres, burning very far up the Entiat River Valley - also in steep, rugged terrain.

The Hope Fire, north of Kettle Falls, is 7414 acres and 25% contained.

The two other large fires in the state are the Greenacres Fire and Western Pines Fire, but both are now 95% contained and producing minimal to no smoke. 

With the hot weather and increased fire activity this week, there have been reports of minor smoke and haze across the state. Luckily, surface air quality has generally remained in the GOOD to MODERATE category. Additionally, a frontal system is moving across the state Friday afternoon, helping to further clear out smoke/haze for most areas. 

This frontal system is also producing high fire danger across eastern Washington. A Red Flag Warning is in place across the Columbia Basin due to a combination of high winds, hot temperatures, and dry air.

After this latest peak in fire danger, temperatures will continue to cool down statewide Saturday into Sunday and fire danger will gradually wane. As a result, active fires will likely produce less smoke going forward into early next week. Still, minor to moderate smoke impacts may continue for communities in close proximity to any new or existing fires.

As a reminder, you can always stay updated on current air quality by viewing the map at the top of the blog site. Have a great weekend!

Canadian smoke and critical fire weather

Smoke from the Placer Creek Fire in Southern BC is impacting communities in northeastern Washington. The fire began over the weekend and has quickly grown to 6400 acres. This morning's satellite image shows the smoke plume moving southeast.

GOES-WEST 14 Jul 2025 15:11Z

Smoke is also visible west of Tonasket:

Smoke visible at Aeneas Mountain west of Tonasket. Image courtesy: DNR/Pano

Smoke from the fire will continue to impact northeastern Washington until shifting winds this afternoon push the smoke south into the Okanogan Valley.

Smoke from the Hope and Western Pines Fires in northeastern WA continue to impact nearby communities. Firefighting efforts on both fires continue, but hot, dry, and windy conditions will challenge efforts and increase fire activity. Communities nearby to both fires should continue to expect intermittent smoke impacts. In general, most of Central and Eastern WA will observe moderate air quality over the next few days due to multiple fires in the region.

Critical Fire Weather Today

Extreme fire weather is expected this afternoon in Okanogan Valley; very strong winds (sustained winds 30-40 mph and gusts up to 50-60 mph) are forecasted for the area. The strong winds in addition to the hot and dry conditions will contribute to critical fire weather in the Okanogan Valley as well as the Columbian Basin. A Red Flag Warning has been issued for most of Eastern WA through Wednesday.

These strong north winds will transport Canadian smoke south into the Okanogan Valley. Any new fire starts will spread quickly and existing fires (including the Pomas Fire) will exhibit increased growth. 

Fire weather concerns will ease Thursday with the return of westerly winds that will also help scour out any areas of poor air quality.  

Western WA Smoke Impacts Tomorrow

Tomorrow winds from the northeast will push Canadian smoke into northwestern Washington (primarily eastern Whatcom, Skagit, and northern Snohomish counties). Most of the smoke will likely stay above us in the atmosphere but a fraction may mix down to the surface tomorrow afternoon leading to moderate air quality at worst. Haze may be noticeable across western Washington before westerly winds return on Thursday.

Statewide smoke update

There are a number of fires across the state causing mostly localized smoke impacts. Moving west to east:

The Bear Gulch Fire along Lake Cushman has increased to 415 acres. Smoke impacts have been minimal thanks to recent cooler weather, but communities closest to the fire should expect intermittent periods of smoke. Authorities are asking people to avoid the north end of Lake Cushman and many recreation sites are closed.

The Toonerville Fire in Belfair (currently 85 acres) has also caused minor smoke impacts to the immediate area. Evacuations are in place; more information can be found from the North Mason Regional Fire Authority.

The Pomas Fire northwest of Entiat continues to grow (currently 3,330 acres) and exhibit active fire behavior. Smoke impacts will continue to be concentrated in the Entiat River Valley.

In Lincoln County, the Western Pines Fire (10 miles north of Davenport) began yesterday and has grown to almost 4,000 acres. Smoke from the fire is currently impacting the Wellpinit area. Smoke will disperse to the east this afternoon. Tonight and into tomorrow morning winds will push smoke to the south of the fire, causing periods of Unhealthy for Sensitive Groups air quality in the Davenport area.

Located about 15 miles north of Kettle Falls, the Hope Fire began on the afternoon of July 8 and has quickly grown to 6,700 acres. The fire is burning mainly in grass and shrubs, and smoke impacts have largely been concentrated in and to the north of Kettle Falls. Local smoke impacts will continue with periods of Unhealthy for Sensitive Groups and potentially Unhealthy air quality closest to the fire. Communities to the south of the fire (including Colville) will likely observe smoke impacts tonight and into tomorrow morning.

Cooler temperatures continue today, but breezy winds may spread smoke. Warm, dry, and windy conditions return this weekend leading to increasing smoke from active fires and rapid spread of any new fire starts. Keep an eye on current and forecasted air quality at the map at the top of this page and we'll update as necessary.

Bear Gulch Fire burns along Lake Cushman, Pomas Fire sees significant growth

Bear Gulch Fire

Folks along the southeastern Olympic Peninsula and around the Puget Sound might've noticed a layer of haze Tuesday morning. 

The Bear Gulch Fire started Sunday evening in the Olympic National Forest along the northern shore of Lake Cushman and produced an impressive smoke plume Monday afternoon and evening.

Warm, dry weather fueled the fire on Monday and has burned approximately 200 acres, per the Olympic National Forest. 

Air quality near the LCMC Park on the east shore of Lake Cushman was UNHEALTHY Monday morning, with improvement to GOOD by Monday night. Air quality has since degraded and is back to UNHEALTHY conditions Tuesday morning.

Slightly higher relative humidity should limit fire growth on Tuesday but expect the fire to continue to produce smoke with the greatest impacts along Lake Cushman. Communities such as Hoodsport, Potlatch, and Skokomish may see periods of UNHEALTHY FOR SENSITIVE GROUPS, mainly in the morning hours.

For updates on the fire, follow the Olympic National Forest and the Mason County Sheriff's Office on Facebook.

Pomas Fire

Jumping over to the Cascades, the Pomas Fire continues to burn in the upper Entiat River valley. Monday was a very active day, with pyrocumulus clouds observed multiple times in the afternoon and evening, and an impressive smoke plume visible on satellite imagery.

The fire grew approximately 415 acres on Monday, bringing the fire perimeter to 2,890 acres.

Despite the impressive smoke plume, air quality across eastern Washington is mostly in the green as the smoke aloft has remained aloft as it dispersed to the east.

The greatest smoke impacts from the fire will continue to be in the Entiat River valley, where UNHEALTHY conditions will continue to be possible each morning following active fire behavior. Air quality is expected to improve to GOOD in the afternoon.

Gusty winds Tuesday afternoon and evening followed by a dry cold front Wednesday may limit overnight drainage and actually reduce these smoke impacts, but these winds and low relative humidity will bring critical fire conditions to the region.

Apple Acres Fire

The Apple Acres Fire is approximately 3,410 acres and 70% contained. With Red Flag Warnings in place, fire activity may increase Tuesday and Wednesday. The remaining fuel the fire could burn is mostly comprised of grass, so any potential smoke impacts will be in the immediate vicinity of the fire.
