Firefighters conduct a night burnout operation in Summerhaven on June 23, 2020.

The Bighorn Fire near Tucson triggered a new round of evacuations Friday afternoon when firefighters evacuated communities on the eastern slope of the Catalina Mountains.

Crews have struggled with the fire, which is burning in steep, rugged terrain. Dry, windy conditions have pushed the fire closer to homes.

The fire has burned more than 88,000 acres and is 40% contained as of Friday evening.
