8/25 Air Quality Report

Incident: Chelan Complex Wildfire
Released: 8/25/2015

Note: The Manson monitoring site has re-established. Yesterday an air monitor was also installed in Brewster.

Tuesday: Decent mixing has allowed smoke to disperse overnight and into the morning in some affected communities. Expect to see generally improved air quality in the afternoon with smoky conditions gradually returning overnight. This pattern will be more apparent in Chelan and Manson. Brewster will see improved air quality throughout the day.

Wednesday: Chelan and Manson will again see varying levels of smoke throughout the day. Twisp and Winthrop will not likely get much relief from the smoke. Leavenworth and Wenatchee may see some smoke drift during the day which should clear out by evening.

Thursday: With uncertain meteorological information at this time, this forecast may change considerably.
