Late this morning, the National Weather Service in Spokane issued an air quality alert for 12 Washington counties including Chelan, Douglas, Grant and Okanogan.

Smoke from wildfires in Idaho, Oregon, and here in Washington are expected to affect most of Eastern Washington until increased wind on Thursday scours out the smoke and allows air improvement.

Until that time, air quality will vary between good and unhealthy depending on wind direction and time of day.

Children, the elderly, and individuals with respiratory illnesses are most at risk for serious health effects from smoke. The air quality alert remains in effect until 10 a.m. Thursday.
