SIERRA VISTA, Ariz. -- Progress is being reported in the fight against a wildfire burning near Sierra Vista in southeastern Arizona.
Fire managers report that the Brown Fire in the Huachuca Mountains is 25 percent contained. That's after low fire behavior Thursday allowed firefighters to strengthen containment lines as helicopters dropped water on the fire.
More than 400 people were assigned to the fire, including 10 ground crews. Helicopters and air tankers also were available.
Fire managers said no structures have been threatened but residents of canyon areas have been told to be ready to evacuate.
The fire is estimated at 240 acres. It's burning in brush and timber in steep and rugged terrain, mostly on Fort Huachuca, an Army base, and in the Coronado National Forest.
The fire started April 13.
