A wildfire in the Boise National Forest is threatening about 100 homes, as lightning sparked several new fires across the state.
The 300-acre Avelene Fire is nearing the Clear Creek Subdivision, about 25 miles east of Boise.
Forest spokesman Dave Olson says no structures have been lost. No evacuations have been ordered but the Boise County emergency management coordinator says they are being planned.
Hand crews, engines, helicopters and air tankers were battling the blaze.
Two additional small blazes were reported burning in the foothills just northeast of Boise near a populated area, likely started by lightning storms that rolled through the area Wednesday morning.
In the BLM's Twin Falls District, lightning storms caused three new fires Tuesday. Officials also are monitoring nine fires in southwestern Idaho.
