In shutting off the electricity, PG&E cut power to the distribution lines that supply homes, but not to its long-distance transmission lines. Meanwhile, an estimated 50,000 people were under evacuation orders in the Santa Clarita area north of Los Angeles as hot, dry Santa Ana winds howling at up to 50 mph (80 kph) drove the flames into neighborhoods. At least six homes were burned. No immediate injuries were reported.
