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
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
In case you wanted to see how the northwest compares to other regions...
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.
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
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
High end fire weather day tomorrow. Be careful everyone! #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
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
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
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
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
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
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
Retardant drop on the #FerrisFire earlier this afternoon. #COwx #COFire
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
