The American Red Cross with the Pima County Health Department are working together to support residents affected by the Bighorn Fire. In addition to helping people take refuge at centralized locations, they will accommodate those who want to evacuate but want to avoid congregating a shelter.

“We have heard from people who don’t have anywhere else to go saying that because they are at high risk for severe complications from COVID-19, they don’t want to evacuate and go to a shelter,” said Courtney Slanaker, Executive Director of the American Red Cross Southern Arizona, in a statement. “We are doing everything we can to avoid congregate sheltering. Your safety is our priority; getting you to a safe area, both away from the threat of fire and isolated from other people who you don’t live with.”
