Dozens of forest and brush fires are currently burning across eight western states, forcing thousands to flee, destroying homes, and closing highways. Enormous volumes of smoke and ash are being thrown into the atmosphere as more than a million acres have burned in the past week alone, creating hazardous breathing conditions in many parts of the Pacific Northwest. In California, the La Tuna fire near Burbank has burned nearly 7,200 acres, becoming the largest fire ever recorded in Los Angeles, in terms of area.
