Two wildfires are currently burning in Washington: the 25 Mile fire near Manson and Lake Chelan, and the Rattlesnake fire 25 miles SE of Keller, WA. Neither fire is expected to cause significant air quality impacts beyond some very light haze, such as can be seen in the picture below taken near the 25 Mile fire. Some residents in areas very close to the fires could experience some more significant smoke and should take precautions if particularly sensitive. More on the 25-Mile fire (including areas subject to evacuation) can be found here: http://www.inciweb.org/incident/3493/
