Authorities are keeping a worried eye on fire-scarred hillsides in Southern California after a storm brought flooding fears and prompted evacuation orders for hundreds of homes.

Thursday's storm brought record-breaking rainfall to downtown Los Angeles, jammed major roads with mud, rain or snow and sent a landing airliner skidding off a runway.

A mudslide shut down roads in and around Malibu neighborhoods charred by a massive wildfire last month.

However, no major injuries were reported.

Mandatory evacuations were ordered for Los Angeles-adjacent counties ravaged by a summer wildfire. Evacuation orders remain in place Friday for Trabuco Canyon in Orange County and the Lake Elsinore area east of Los Angeles.

Forecasters say it will be warmer and drier before another storm moves in next week.
