BEND, Ore. – Officials have told residents near a 140-acre wildfire burning about 11 miles west of the central Oregon city of Bend to be ready to evacuate.

Fire officials tell KTVZ-TV that the fire near the popular recreation area of Tumalo Falls is 10 percent contained on Saturday morning.

Deschutes County sheriff’s Sgt. Nathan Garibay says residents of a subdivision of homes and cabins are under a pre-evacuation notice through Saturday.
