BELLVUE, Colo. (AP) - Authorities are ramping up the fight against large wildfires burning out of control in northern Colorado and southern New Mexico.
Ten air tankers, half of them large aircraft, were at a fire burning on nearly 60 square miles in a mountainous area about 15 miles west of Fort Collins on Monday. One person is missing in the fire.
In New Mexico, fire managers were hoping to use a break in the weather to fight a 54-square-mile blaze near Ruidoso from the air. Winds grounded aircraft there Sunday.
Residents in Ruidoso have been warned to be prepared to evacuate if conditions worsen.
Both fires have destroyed dozens of structures, including an unknown number of homes.
