Welcome to the Washington Smoke blog, a partnership between state, county, and federal agencies, and Tribes. We coordinate to collectively share information for Washington communities affected by wildfire smoke.

Air quality forecast, Friday 11 July 2014
Issued by Ranil Dhammapala, Washington State Dept. of Ecology
The Mills Canyon fire has grown to over 18,000 acres now and there are reports of a few new fires in Chelan county. As of 1PM today, the new air quality monitor at Entiat is showing Unhealthy air. Air quality in Leavenworth and Wenatchee have been hovering between Moderate and Unhealthy for Sensitive Groups. Due to the absence of south winds, Chelan has mostly been spared of smoke thus far. Some smoke drifted eastward over north-central Washington, but has mostly stayed aloft.
Overhead smoke might in fact trim a few degrees off blistering daytime temperatures in some areas over the next few days. Cities near the fires including Entiat, Wenatchee, Leavenworth and Chelan will continue to see periodic smoke impacts at ground level. Winds will be weak to moderate, mostly driven by local terrain. Smoke is unlikely to blow far into the Columbia basin but could push up against the Cascades through Sunday and may even cause some hazy conditions just west of the Cascade crest. However no significant smoke is expected in western Washington.
There is a chance of some dry lightning on Sunday night into Monday in the northern mountains of Washington. The heat wave is set to continue through Wednesday at least.
As an aside, some users might have noticed intermittent discrepancies in colors shown on the map of air quality monitors above, and those reported on the Department of Ecology's official page. This is because Ecology’s method of calculating the air quality category (i.e. “Good”, “Moderate”, Unhealthy” etc) is more protective of public health than the method used by EPA. Please contact me if you’d like further details.
Have a nice weekend!

7/11/2014 Monitor now in place in Entiat
Also, the display times (shown along the bottom of the graph) are in "Coordinated Universal Time" or UTC so you need to subtract 7 hours to get local time (Pacific Daylight Time). So for example, the peak reading from the instrument was recorded at 07:00 UTC which would translate to midnight last night local time.
The peak value was about 130 µg/m3 (micrograms of particulate matter per cubic meter of air). These readings certainly reveal smoky conditions in Entiat! More specific health warnings to follow as this new data is analysed by our experts. In the short term, please contact Chelan/Douglas Health District or a medical professional if you have specific concerns about heath effects from the smoke.

Smoky Conditions July 9
Smoky Conditions in Some Areas near or Downwind from the Mills Canyon Fire

Air quality forecast, Wednesday 9 July 2014
Issued by Ranil Dhammapala, Washington State Dept. of Ecology
As Janice noted below, the Mills Canyon fire near Entiat is creating a lot of smoke. Satellites have detected a fire near Quincy but it appears much smaller than the one near Entiat. The last few frames of the visible satellite imagery on Tuesday night suggest that smoke from the Mills Canyon fire blew across Entiat, Ephrata and Moses Lake. The passage of a dry front this morning may have helped prevent a worse buildup of smoke, even though some smoke still lingers on.
Weather and air quality forecast models suggest that smoke is likely to impact these areas again later today & tomorrow. Smoke will also blow further into the Columbia basin on Thursday. Wenatchee and East Wenatchee might see some smoke early Thursday AM & night. Winds turn east on Friday and Saturday, which might bring some clearing to the Basin, but will push smoke up against the Cascades. Chelan and Stehekin could potentially see some smoke on Friday & Saturday.
In spite of east winds, the smoke from the Mills Canyon fire is not expected to impact Western WA over the next few days.
The National Weather Service issued a red flag warning, as dry, windy conditions develop in the Columbia basin now through this evening. These can cause fires to spread rapidly.
http://forecast.weather.gov/wwamap/wwatxtget.php?cwa=otx&wwa=red%20flag%20warning
We are expecting a strong ridge of high pressure that could lead to a 4+ day hot spell starting Saturday. Does not bode well for fire safety nor smoke dispersion.
Smoke dispersion forecasts will be made available as necessary.
Thanks.

6/27/14 Hay Canyon Fire Update
Contacts: Robin DeMario, 509-664-9292
Wenatchee—The Hay Canyon Fire, located approximately two miles north of Cashmere, is now estimated to be 300 acres. Firefighters completed burnout operations and were able to construct a fireline around the entire fire.
Islands of burning fuels remain in the interior of the fire and smoke will be visible in the fire area for the next few days. Isolated rain showers fell over portions of the fire this afternoon.
Evacuation Level 2 is in effect and will be reduced to Level 1 by late evening. The road closure has been lifted and no structures have burned.
Today’s firefighting resources included three 20-person crews, two fire engines and a helicopter that delivered water as needed. Firefighters will be patrolling the fire tonight and crews will return on Friday to continue mop-up operations.
The fire started late Wednesday afternoon and is burning in grass, brush and timber in very steep terrain. The cause of the fire is under investigation.
On Wednesday, two firefighters sustained minor injuries when they were struck by rolling rocks; no further injuries have occurred.
