Fire crews across the western United States and Canada spent the weekend racing to protect entire towns as wind-driven wildfires forced more than 100,000 people from their homes and left at least two people dead. The most severe emergency unfolded in British Columbia's Okanagan Valley, where the fast-growing Bald Range fire forced the entire evacuation of Summerland and killed an elderly resident, even as firefighters in eastern Washington neared full containment on fires that had already leveled hundreds of homes near Spokane. Meanwhile, a heat wave fed a cluster of new blazes across California, including one that claimed a life in the Sierra foothills.
