The heaviest amounts of rain are expected to come through Saturday afternoon, according to the National Weather Service.

A strong atmospheric river is pummeling Southern California, bringing a widespread risk of floods and prompting evacuations.

After some moderate showers during the morning rush hours, more parts of Southern California saw light rain and drizzle during the late morning hours. Residents in burn scar areas braced for possible mud and debris flow with rain expected in Southern California over the next several days.

The rain could also lead to washed-out roads, debris flows and damaging winds – making travel difficult or dangerous, forecasters warn.

In less than 24 hours, California experienced nearly a dozen weather and natural events - heavy rain, flooding, lightning, snow, high winds, landslides, fog, blowing dust, wildfires, a rainbow and an earthquake. And this came just one day after the aurora illuminated skies across the state and much of the nation.

A storm is dropping rounds of heavy rain on more than 22 million people across Southern California on Saturday.
