IDAHO CITY, Idaho (AP) — Firefighters are setting up sprinkler systems to protect buildings in the central Idaho town of Lowman as a wildfire on Wednesday expanded to 75-square-miles.

Officials say slightly cooler weather and winds from the northwest should help firefighters trying to prevent flames from reaching the small town. Fire spokeswoman Jennifer Myslivy says there are no evacuation notices. Nearly 1,500 firefighters are battling the blaze burning timber in rugged terrain and that grew by more than 9 square miles.

Fire crews have repeatedly had to abandon fire lines as the fire moved north but Myslivy says crews are trying to build another one using a prescribed burn near the town of Lowman. State Highway 21 is closed from 6 miles north of Idaho City to south of Lowman.
