Personnel from Spokane County Fire District 3 and the state Department of Natural Resources were working to contain the fires on Monday, while a record-breaking heat wave threatened to maintain ample supplies of dry air and fuel.

A fast-moving wildfire in Spokane destroyed at least 15 homes and left one person presumed dead after human remains were found in a home where the occupant had refused to evacuate. Thousands remained under evacuation orders as crews worked the fire.
