An arson suspect in custody is believed to be responsible for starting the uncontrolled Palisades Fire in Southern California, Los Angeles Mayor Eric Garcetti said Monday.

Officials said firefighters made progress against the fire, and evacuation orders were lifted for the Topanga Canyon area. The fire, which started late Friday about 20 miles west of downtown Los Angeles, prompted the evacuation of about 1,000 residents.

The fire has burned 1,325 acres and is 25% contained, Los Angeles Fire Department (LAFD) officials said Monday evening, up from 0% containment in the morning.

One firefighter suffered a minor injury to his eye, fire officials said. No structures have burned.

Some drizzly rain in the area and an inversion layer have helped prevent the fire from spreading, the mayor said earlier. That marine layer tends to trap heat, and Garcetti warned that once the clouds lift, typically in the afternoon, flames have the potential to take off rapidly.

California has been in a massive drought for weeks, and experts worry it will only get drier and hotter, creating the potential for another devastating wildfire season.
