Dangerous conditions are expected to persist through Friday before flame-fanning winds subside slightly, potentially giving crews a foothold against infernos that have killed at least 10 people.

Fierce winds fueled new fires and made it harder to contain the largest blazes, which have destroyed whole neighborhoods and have become some of the most devastating in California’s history.

Multiple wildfires, including the Palisades Fire and Eaton Fire, are raging across Southern California Friday, leaving at least 10 dead and burning more than 10,000 homes across 27,000 acres, officials say.
