Maurizio Fugati, president of the Trento region, said drone searches would continue as three other people, all Italian, remained missing. A police team specializing in DNA analysis has also been set up to assist in the identification process. Much of Italy is baking in an early summer heatwave, and scientists have said climate change has made previously stable glaciers more unpredictable. Rescue coordinators hope to supplement the work of drones and helicopters by sending a team of experts and search dogs to the bottom of the site on Thursday, when the weather is forecast to be clearer. Parts of the mountain will remain closed to tourists to allow rescue teams to attempt and prevent climbers from accessing potentially dangerous areas. The local Fassa Valley will observe a day of mourning on Saturday to honor the victims, who included two tourists from the Czech Republic.
