CORONADO NATIONAL FOREST, Ariz. Firefighters have cut a rough line around a wildfire burning in the Coronado National Forest near the Mexican border. However, forest spokesman Gail Aschenbrenner says fire crews remain concerned because of windy and dry conditions expected in the area today. Aschenbrenner says crews made good progress on fighting the fire last night and are working to strengthen their fire lines. The fire has burned across 121 acres in the remote area west of the Coronado National Memorial. No structures are threatened.
