LOS ANGELES — Southern California faces the continued risk of rock and mudslides on wildfire-scarred hillsides Friday, a day after heavy rains sent debris across several roadways, including the Pacific Coast Highway, where a fire department vehicle was pushed into the ocean.

As Southern California recovers from last month’s devastating wildfires, heavy rains Thursday resulted in pockets of flooding, blocked roadways and mud piling up around recent burn scars.

Parts of Pacific Coast Highway remained closed due to heavy flooding and mudslides in Southern California, according to state officials.

A swift debris flow swept a Los Angeles Fire Department vehicle off the Pacific Coast Highway and into the ocean as heavy rain fell across Southern California on Thursday, creating deluges of water and mud on roads at the bottom of hillsides left barren by recent wildfires.
