Air Quality Forecast - Chelan Lake & Methow Valley Fires       Saturday, August 29, 2015

Prepared by:   Andrea Holland (andreahollandsears@gmail.com) & Carolyn Kelly (ckelly8384@gmail.com)             

Note that our forecast format has changed.  Starting today we will be showing air quality conditions for the previous day along with forecasts for today and tomorrow. Saturday: With the passage of a powerful cold front today, winds will move smoke away from communities in the vicinity of the Wolverine, First Creek, and Chelan Complex fires.  Some smoke may drift in but will be transient and not remain. This may be a great time to air out the house. Sunday:  Following Saturday’s storm passage Chelan, Manson, and Brewster will see smoke settling into these areas beginning mid-afternoon.  Due to their proximities to the fires, Manson and Brewster may see heavier concentrations with Brewster approaching levels unhealthy for sensitive groups. This will be short lived as the smoke is expected to generally clear overnight in each of these areas.
