Mandatory evacuations for more than 100,000 people remain in place for the wildfires, which started Jan. 7 amid a powerful windstorm that forecasters warned would be the worst the region has seen in more than a decade.

Firefighters scrambled Sunday to make further progress against wildfires that have destroyed thousands of homes and killed 24 people in the Los Angeles area as forecasters again warned of dangerous weather with the return of strong winds this week.
