The National Weather Service expects rain to start hitting Wednesday evening along with gusty winds into Thursday. As much as 1/2 to 2 inches of rain is expected.
Locals have begun stacking sandbags and taking other steps to protect their properties. Malibu, Agoura Hills, Thousand Oaks and other places where the Woolsey Fire left hillsides exposed and vulnerable to mudslides could be at risk again.

Meanwhile, crews are working to stabilize the hillsides. In Agoura Hills, Los Angeles County Fire Department officials have strategically placed heavy equipment in areas that are possibly threatened.
By Wednesday night, sandbags piled along properties there. Members of a local church piled sandbags in front of the Seminole Springs Mobilehome Park.
"I live in the first house right here, and I'm pretty concerned about the mud coming down," said resident Houston Waye.
Just down Mulholland Highway, Mark Sand moved hundreds of sandbags. He runs the Hearts and Horses Therapeutic Riding Center and said he expects to have a sleepless night.
"I stayed here during the fires, I'll stay during the floods," Sand said. "I have 10 horses down there...I'm committed."
Authorities are warning residents to prepare for possible evacuations and plan ahead for road hazards, flooding and outages ahead of the rain.
The U.S. Geological Survey released a map showing mudslide risk for areas impacted by the Woolsey Fire.
The Woolsey Fire started Nov. 8 in Simi Valley near the Rocketdyne facility in the Santa Susana Pass. It quickly triggered evacuations in Ventura and Los Angeles counties.
The fire destroyed more than 1,600 structures; three people died in the blaze. The cause of the Woolsey Fire remains under investigation.
The storm is also raising concerns for people living near the Holy Fire burn area.
In Lake Elsinore, which endured the large Holy Fire in August, preparations were made to shore up a 60-year-old dam that sits directly above homes. It could be the last line of defense for properties, but if the rain becomes too intense it may not be enough.
The following areas were affected: Amorose, Alberhill, Glen Ivy A, Glen Eden, Grace, Horsethief A, Laguna A, Matru, McVicker A, Rice and Withrow A zones.
The Lake Elsinore Unified School District announced four schools -- Rice Canyon Elementary, Withrow Elementary, Luiseño School, Terra Cotta Middle School - would be closed Thursday.
Flood control officials said their main concern comes when a portion of the storm moves into the area Thursday.
Residents living in the Cranston Fire burn area in Idyllwild were also warned about avoiding areas susceptible to debris flow.
