The fire has threatened hundreds of homes[6] and the Pima County Sheriff's Department has asked residents in the area to evacuate. The first evacuations occurred in the Catalina Foothills neighborhood in Northern Tucson. The following day, residents in the Oro Valley section of the Catalina Foothills were ordered to evacuate.[7] On June 16, Mount Lemmon and Summerhaven were evacuated.[8]

As of June 27, the fire is 45% contained. The fire was at 40% containment once before, but fire crews working on the fire had lost containment and it dipped down to 16% before rising again. Fire crews have struggled to fight the fire due to the heat and dry weather. The majority of the days since the fire begun had over 100 degree temperatures with low humidity, as is typical in June in Tucson.[1]
