A wildfire east of Nogales, Ariz., has consumed about 2,500 acres and is 5 percent contained, officials said Monday morning.

There are about 200 people assigned to fight the Soldier Basin Fire, which began about five miles east of the Nogales airport. There are two helicopters, 11 engines, seven water tenders and other aircraft fighting the human-caused fire, according to a news release from the Coronado National Forest.

The fire is burning mainly grass and brush in steep, rocky terrain. No structures are threatened.

Fire crews are trying to keep the fire south and west of Flux Canyon, west of Forest Road 49, north of the Soldier Basin drainage and east of the forest boundary, forest officials said.

Winds today are expected to gust to 35 mph, but should ease into the evening hours.

Residents can expect to see more smoke today as crews continue doing burnout operations to clear off natural fuels for the fire.
