The death toll from the multiple fires raging across Los Angeles County rose to 10 on Thursday night, as the largest of the five blazes—the Palisades Fire—grew to cover nearly 20,000 acres as strong winds meant the “Red Flag” fire weather conditions will remain in effect until Friday evening.

The biggest wildfires ravaging the Los Angeles area have killed at least 10 people and burned more than 10,000 homes and other structures.
