Inversion season + wildfire smoke = 😷 This is the view from Chelan Butte looking south toward the Columbia River. Although fire behavior has moderated, smoke impacts will continue in the valleys surrounding the fires until we see substantial rain. #wawx #wawildfire

DNR Pano cam. Don’t think it’s on the public site… :(

The #KingFire (left) and #ThreeQueensFire (right and front) are also seeing activity pick up as we head into the evening hours. #wawx #wawildfire

The #SinlahekinFire and #LittleGiantFire are both producing pyrocumulus clouds this afternoon as hot, dry, and windy conditions continue east of the Cascades. It is still late August. Fire behavior is not seeing a substantial decline. #wawx #wawildfire

A few small ignitions have combined into one just north of Mount Rainier. I believe this is being called the #WestForkFire. This will likely continue to burn actively today and tomorrow before RH improves. #wawx #wawildfire Image courtesy: Crystal Mountain

It's not often you see a large air tanker on a fire in the western Washington lowlands... #HiddenMeadowsFire #wawx #wawildfire

New incident in western Washington north of Battle Ground. Structures threatened, Level 3 GO NOW evacuations in place, aviation resources on scene. This is being called the #HiddenMeadowsFire. #wawx #wawildfire

Very concerning situation unfolding tonight as the #ColwashFire burns closer to Prosser. Several structures have already been threatened near Mabton. #wawx #wawildfire

Dangerous fire weather conditions will begin to unfold later this afternoon through the day Saturday with widely scattered dry thunderstorms, gusty winds, and low relative humidity all in play. Red Flag Warnings are up for the Olympics, Cascades, and all of eastern WA. #wawx #wildfire

After several days of minimal activity, the #ThreeQueensFire flared up yesterday as the thermal trough crossed the Cascades. It continues to burn actively this afternoon. Just goes to show how dry the fuels are right now. #wawx #wawildfire

Nathan Santo Domingo @nsdwx.bsky.social · 05/08/2026
Just something to watch in the long-range. This trough just off the west coast has been showing up in the ECMWF weeklies for a few days now. Now the EPS is coming into range. A lot to iron out between now and then, but this would certainly be a watch out pattern for dry lightning. #wawx #wawildfire

Monitoring a new ignition west of Spokane near Long Lake. Aviation resources are on scene. This is being called the #CharlesFire. #wawx #wawildfire

As of 1:00 PM, over 1,601 sensors across Washington and Oregon are measuring Unhealthy air quality or worse. Only 39 out of 2,588 between the two states are currently Good. Check in on friends and family. Smoke is a serious health hazard. #wawx #wasmoke Smoke Resources ➡️ www.dnr.wa.gov/smoke

It's been fascinating to watch the battle between the NW winds out of the Strait of Georgia with the easterlies coming down the Fraser and Skagit valleys. One of the trickier parts of this AQ forecast. Very tight gradient between Good and Unhealthy air. #wawx #wasmoke

In case you wanted to see how the northwest compares to other regions...

Nathan Santo Domingo @nsdwx.bsky.social · 04/08/2026
The air quality continues to deteriorate across the Pacific Northwest. In WA and OR, 70% of all monitors and sensors are showing USG (orange) or higher. Everyone should take steps to keep their indoor air clean and limit time outside! #wawx #orwx #wasmoke #SmokeReady 🔗 www.dnr.wa.gov/smoke

I haven't been doing as great a job sharing the Smoke Blog this year, so I'm going to start! Today's post has a lot of good info in it from smoke/heat safety to indoor air quality tips to when the smoke will start to clear. #wawx #wawildfire #SmokeReady 🔗 wasmoke.blogspot.com/2026/08/smok...

Another new wildfire has started NW of the #OldTrailsFire. This is being called the #AutumnLaneFire and is currently south of Charles Road. This is WEST of the Spokane River. #wawx #wawildfire.

Nathan Santo Domingo @nsdwx.bsky.social · 01/08/2026
This is about a worst case scenario that you can imagine for Spokane. Level 3 GO NOW evacs extend all the way to Division. Absolutely heartbreaking. #wawx #wawildfire #OldTrailsFire

NEW WILDFIRE NEAR SPOKANE. This is burning near Fairview Ave south of Mead. Evacuations have just been issued. #wawx #wawildfire

Nathan Santo Domingo @nsdwx.bsky.social · 01/08/2026
The #OldTrailsFire has jumped the Spokane River along Aubrey L White Pkwy south of the Spokane Rifle Club. Radio traffic reports the fire is moving 100 yards a minute. If you are in a level 3 zone, you need to LEAVE NOW. #wawx #wawildfire

Very concerning situation north of Spokane Int'l Airport with a fast-growing fire that is moving to the northeast. 12:53pm observation at the airport: 84F, 23% RH, wind WSW 23mph gusting to 36. This is being called the #EuclidFire. #wawx #wawildfire

Stumbled upon this spooky DNR Pano cam shot of the #SinlahekinFire last night. Really don't like the trajectory this fire is on. Several days of big growth potential lie ahead. #wawx #wawildfire

Nathan Santo Domingo @nsdwx.bsky.social · 29/07/2026
The #SinlahekinFire, burning north of Conconully, has shown very active fire behavior this afternoon. This one will be on the landscape producing smoke for a while... #wawx #wawildfire

Nathan Santo Domingo @nsdwx.bsky.social · 27/07/2026
New fire somewhere S/SW of Toppenish. Looks to be near HWY 97. Not yet on Watch Duty. You can also see the PyroCb from the #GrasshopperFire in the background. #wawx #wawildfire #orwildfire

White Swan situation is awful. Seems very suspicious

Nathan Santo Domingo @nsdwx.bsky.social · 26/07/2026
Two new fires could be on the landscape for a while. The #SinlahekinFire (photo 1) west of Tonasket is in difficult terrain for initial attack. The #BradeenHillFire (photo 2) across the Columbia from Inchelium is being bombarded by aviation resources with structures threatened. #wawx #wawildfire

This is already the third highest acreage for DNR responses alone in the last decade and it’s not even August. I truly do not understand how a certain local weather blogger thinks false statements like these are helpful ahead of our most critical fire weather day of the year. #wawx #wawildfire

Nathan Santo Domingo @nsdwx.bsky.social · 24/07/2026
The #LittleGiantFire burning north of Lake Wenatchee is now over 10,000 acres and is going on one heck of a run this afternoon. Critical fire weather continues through the weekend. Very concerned about tomorrow's wind and low RH. #wawx #wawildfire

Nathan Santo Domingo @nsdwx.bsky.social · 21/07/2026
A lot of potential for new ignitions and rapid fire spread the next few days. The lightning threat begins WED evening through THU evening, then the winds ramp up. Go over your evacuation plan and stock up on supplies just in case. Everyone needs to practice good fire safety. #wawx #wawildfire

Farewell, Utah! My time on the #BabylonFire has come to an end. Thankfully, Mother Nature is (mostly) cooperating and fire behavior has moderated considerably. Thank you to Great Basin Team 2 for making my first fire assignment a good one. #UTwx #UTFire

No words. Here is a peak at one of our most incredible drone flights around a #tornado to date near Tulliby Lake, AB. This will likely be one of our last intercepts of the season, thank you so much to everyone for following along! #stormchasing #nature #weather

Really cool opportunity to help launch a sonde with fellow @uwatmossci.bsky.social grad and IMET Tom Schuldt in support of the #BabylonFire. PWAT of 0.72" and DCAPE of 1335 J/kg raises concerns for dry lightning and strong outflow winds today. Photos to come! #UTwx #UTFire

Sunset on my 10th day on the #BabylonFire. Some concern for tonight’s air quality as a strong ridge of high pressure begins to build overhead. Wouldn’t be shocked to see some Unhealthy readings. #UTwx #UTFire

Jaw dropping timelapse from the #BabylonFire. Observed torching several times near the ridge top. Shot near Blanding City 4th Reservoir. #UTwx #UTFire

A few intra-cloud lightning strikes are being detected in the vicinity of the #BabylonFire and the #FerrisFire by the Geostationary Lightning Mapper aboard the GOES-19 weather satellite. A few cloud-to-ground strikes are possible this afternoon. #UTwx #UTfire #COwx #COfire

Well, night 5, day 4 :)

Fire activity was limited today, but a new column went up late in the day as the fire hit a strand of heavier fuel. Still hot and dry, but less wind. Watching iso t-storms Monday-Tuesday then stronger winds Wednesday. Goodnight from night 4 on the #BabylonFire. #utwx #UTFire

Ventured to the Needles Overlook today to observe smoke from the #BabylonFire. Smoke was slow to clear from this morning. This might have played a role in a slightly less active fire this afternoon. We also found a neat rock formation. #utwx #UTfire

Nathan Santo Domingo @nsdwx.bsky.social · 02/07/2026
Air quality data is flowing at ICP for the #BabylonFire. Southwest winds have brought good AQ back to camp, but we expect deteriorating conditions overnight as smoke settles along HWY 191 following another active day of fire activity in the region. #utwx #UTfire

Nathan Santo Domingo @nsdwx.bsky.social · 01/07/2026
My home for the next two weeks. I’m on my first fire assignment as an Air Resource Advisor trainee at the #BabylonFire in eastern Utah and will hopefully be posting frequent air quality updates throughout my assignment! #UTFire #utwx

I recommend Watch Duty for emerging incidents. DNR wildfire intel dashboard and Inciweb are good for daily incident updates and data tracking. Not concerned about this for the Tri-Cities

New wildfire near Lake Wallula has prompted Level 3 evacuations for the Green Valley RV Park #wawx #wawildfire

This fire season is insane already and the PNW hasn’t even fully come online yet…
