Plumes of smoke continue to rise over the Boise mountains and settle into the Treasure Valley, causing unhealthy air quality, especially for sensitive groups. The air quality is marginally better than yesterday, but Boise is still rated "moderate" according to real-time air quality monitoring by the Idaho Department of Environmental Quality.
The smoke comes from the Walker Fire, burning eight miles southwest of Idaho City. According to a fire update from the Idaho Department of Lands, the fire is now estimated to be 3,400 acres—compared to the 2,500 acres it was on Oct. 12.
Firefighters have been able to keep the fire from growing closer to Highway 21 and nearby homes. It's burning in a northernly direction, deeper into heavy timber—causing heavy smoke. It's not threatening any homes in that direction. The containment lines near the Clear Creek subdivision are holding strong, but evacuation orders are still in place.
More than 200 firefighters are on the fire today, with five helicopters ready to drop water on the northwest corner. Grimes Creek Road all the way to Centerville is still closed today, as well as the Boise National Forest inside the Grimes Creek area.
