More firefighters battling blaze in southern Ariz.
Smaller planes scout the spread of the fire, and help guide both tankers and ground crews
SIERRA VISTA, Ariz. (AP) - More firefighters are battling a blaze burning in the Huachuca Mountains in southeastern Arizona.
Fire managers say aerial mapping now puts the Brown Fire at 240 acres, down from the previous estimate of 366 acres. Crews are clearing lines on the fire's flanks but there is zero containment so far.
More than 400 people are now assigned to the fire, including 10 ground crews, several engines and numerous helicopters. Air tankers also are available.
Fire managers say no structures are currently threatened but residents of canyon areas have been told to be ready to evacuate.
The fire started April 13 and is burning in brush and timber in steep and rugged terrain in the Coronado National Forest.
The fire is approximately five miles southwest of Sierra Vista.
