TUCSON, AZ - Lightning sparked a large fire Saturday afternoon in southern Arizona, according to officials.
Officials with the Arizona State Forestry and Sonoita-Elgin Fire District said that the wildfire, called the O'Donnell Fire, is located three miles southeast of Elgin, Ariz., which is about 50 miles southeast of Tucson.
Sonoita-Elgin Fire District Battalion Chief Kevin Venos says the O'Donnell Fire doubled in size Saturday evening when the wind shifted during a burnout operation in O'Donnell Canyon. He says the active fire is chewing through heavy sacaton on the Babacomari Ranch, halfway between Sonoita and Sierra Vista, but no buildings are at risk.
The fire was reported around 3 p.m. Saturday after lightning sparked the blaze, according to the incident report.
Officials estimate that the wildfire has burned 600 acres and is 65 percent contained.
Fire crews listed the wildfire's growth potential as high Saturday but an update Sunday stated that fire behavior was minimal and was not expected to grow further.
