The Idaho Department of Environmental Quality is cautioning residents of the Treasure Valley that the air quality on Friday, Aug 16, is expected to deteriorate even further.
An Orange Air Quality Alert has been issued for Friday, with an AQI index of 125 (Thursday's AQI was 110.)
Smoke from the region's wildfires continues to be "variable and unpredictable," according to DEQ officials, especially in the Boise and southeastern Treasure Valley. Some areas are expected to experience heavier smoke impacts than others throughout the day. Due to the lingering smoke, air quality is expected to be unhealthy for sensitive groups including the elderly, children and people with respiratory or heart disease.
Meanwhile, a Red Flag Warning remains in effect until 6 p.m. Friday, Aug. 16 for areas north and east of Boise, including portions of the Boise, Payette and Sawtooth national forests.
