Parts of Southern California will be slammed with destructive winds leading to possible power outages and elevating the possibility of wildfires. How to prepare for blackouts

Southern California Edison, one of the major electricity providers, could shut off power to more than 409,000 residents amid a major Santa Ana windstorm this week.

This is the third time in as many months that strong Santa Ana winds have prompted Southern California Edison to cut power to its customers over fire risk.

Southern California Edison says tens of thousands of its customers were without power early Wednesday as a powerful windstorm wreaked havoc across the region, fanning wildfires and creating dangerous conditions.
