Arizona Wildfires

The Bringham Fire in eastern Arizona had burned 19,901 acres and was 20% contained as of Monday night, according to authorities.

The Bush Fire outside of metro Phoenix has grown to nearly 187,000 acres and was 61% contained as of Monday night, fire officials said.

The Bush Fire northeast of metro Phoenix is historically large, but Arizona has seen four other wildfires that were more massive.

Buffelgrass is an invasive, non-native grass that is known to spread and intensify wildfires, and scientists believe it's doing just that in Tucson.

The massive Bush Fire northeast of metro Phoenix continues to grow and had consumed nearly 115,00 acres by Thursday morning.

The Bighorn Fire in southern Arizona's Catalina Mountains near Tucson has burned 23,892 acres and remained 40% contained Wednesday night.

The Bush Fire raging northeast of the Phoenix area continues to eat up land in the Tonto National Forest with little containment, officials said.

According to the Arizona Department of Forestry and Fire management, more than 200,000 acres of private, federal and tribal land have burned in 941 wildfires as of Wednesday.

Officials issued a new evacuation order Tuesday afternoon for residents near the Bighorn Fire in southern Arizona's Catalina Mountains.

The Bush Fire northeast of metro Phoenix surged overnight and is fast becoming one of the largest wildfires in Arizona history.
