Here is the air monitor and weather update for Sunday (Sept. 30, 2012). For more information, check http://wasmoke.blogspot.com/.
All other fine particle monitors in Washington are reporting “good” air. Ritzville, Moses Lake, Wellpinit and Colville saw some short-term spikes in fine particle pollution Saturday evening, most probably as smoke was exiting through the Columbia Basin.
On Sunday, communities near wildfires should experienc moderate winds with smoke impacts. Smoke is likely to drift into the Columbia Basin, but not fill it. Expect some afternoon clearing. Areas to the east of the Basin are likely to see little or no smoke through Monday evening.
A strong cold front is expected Tuesday, but winds will start increasing by Monday evening and help with smoke dispersion. While precipitation appears to be confined to the North Cascades and the far northeastern part of the state, winds will likely kick up windblown dust in the Columbia Basin on Tuesday.
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
The Governor has extended a burn ban on all outdoor burning in eastern Washington through midnight Sunday. The ban does not apply on tribal lands where the U.S. Environmental Protection Agency has jurisdiction.
