Washington Smoke Map

*The map above is not able to display all state air quality monitors. Click here to see all monitors in Washington: WA Ecology Air Monitors

Note: Some users might notice 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 believes their method of calculating the air quality category (i.e. “Good”, “Moderate”, Unhealthy” etc) is more protective of public health in Washington. If in doubt as to which better represents public health risk, use the more stringent of the two (i.e. the map showing worse air quality).

9/25/12 Air quality improves for some short-lived relief

Washington Department of Ecology news

FOR IMMEDIATE RELEASE – Sept. 25, 2012

12-323

Air quality improves for some short-lived relief 
 YAKIMAFor the first time in nearly two weeks, none of the air quality monitors in the state are recording hazardous conditions. Pateros comes precariously close, though, with air quality there degraded today while other nearby sites showed improvement in response to a passing front.
            Meteorological data in the area show winds picking up, but the sheltered location of Pateros probably resulted in smoke pooling in the area.
Trout Lake, Winthrop, Omak, Chelan and Entiat remain unhealthy, while Wenatchee, Cashmere, Twisp, White Swan and Toppenish, registering unhealthy for sensitive groups, are clearing out quite well.
Ellensburg, Cle Elum, Quincy, Leavenworth and Yakima all have good air. Sites around the Columbia Basin vary from good to unhealthy for sensitive groups.
A front passing through Eastern Washington right now should help keep smoke levels in check through this evening, according to Ecology meteorologist Ranil Dhammapala.
            “Sadly this improvement is short lived: a building ridge will cause a return to stagnant conditions through Friday,” Dhammapala said. “Strong nighttime inversions and light winds will ensure smoke sloshes around and causes the kind of impacts we have been living with over the last two weeks.”
            Mild east winds return on Thursday and it is possible that these may bring some smoke from Idaho wildfires to the Palouse/ Clarkston areas. In general, expect some smoke impacts in the morning and nighttime, with some afternoon clearing in most places.
            There is no significant precipitation in the five-day forecast. Slight increases in wind speeds on Friday should help with dispersion in Eastern Washington.
            A few areas in the south Puget Sound, Southwest Washington and the Olympic Peninsula might have smelled a whiff of smoke yesterday morning as the inversion broke, but not enough to degrade air quality much. Wildfire smoke is not expected to push west of the Cascades, but with light winds over the next few days, expect a slight buildup of locally and regionally generated pollutants.
            The Governor has extended a burn ban on all outdoor burning in eastern Washington through midnight Sunday.

The National Weather Service issued an Air Quality Alert for all of eastern Washington: http://forecast.weather.gov/wwamap/wwatxtget.php?cwa=otx&wwa=air%20quality%20alert

Broadcast version
After nearly two weeks many communities in Central Washington are experiencing some relief from area wildfire smoke.
No air quality monitors in the state are registering in the hazardous zone. But the reprieve may be short lived, the Department of Ecology says.
A building ridge will cause a return to stagnant conditions through Friday.
Strong nighttime inversions and light winds will ensure smoke sloshes around, causing the kind of impacts we have been living with over the last two weeks.
