Drenching rain will spread over California on Tuesday, bringing some relief to the ongoing drought and raising the risk of flash flooding.

While a series of storms have brought rain to parts of northern and central California over the past few weeks, Tuesday’s storm will bring the first significant rain event for Southern California since the the spring.

Some rain moved over the state on Sunday ahead of this week’s storm, giving a preview of what is to come.

Part of the Pacific Coast Highway near Malibu, California was closed on Sunday afternoon due to multiple rockslides, according to Mike Lindbery, public information officer for the Ventury County Fire Department. Several cars were blocked in, but the passengers were able to get out with no reported injuries according to Lindbery.
