8/11/2014 Widespread poor air quality from smoke

The combination of active fires throughout the Washington Cascades plus hot, stable air is leading to uniformly poor air quality east of the Cascades from Canada to Oregon. Monitor readings for the last 3 days are shown below from North to South (Wenatchee is not shown as the monitor is not functioning properly at this time).  All sites show UNHEALTHY air quality, with the exception of Yakima which is a little less impaired and in the UNHEALTHY FOR SENSITIVE GROUPS category.  Ellensburg was in the VERY UNHEALTHY category earlier today but has improved somewhat.  Health warnings associated with these readings can be found here:
