Heavy rains and mountain snow are spreading across California and will put floods, landslides and travel delays at risk on Friday.
Measurable rain is expected in the largest cities of the state, including Los Angeles, San Diego, San Francisco and Sacramento.
Mandatory evacuations have already been issued for people living near the burn scar caused by the risk of fires and mudslides, while those of Malibu near the burn scar caused by fire from Woolsey were put on alert for possible evacuation.
"Giving Pass could measure the snow in feet from here Friday morning, and it's not excluded that it's necessary to turn it off for a while Thursday to Thursday night, when the big Snow should fall, "said Jake Sojda, Meteorologist at AccuWeather.

Because it has not rained abundantly for so long, the trees have still not been peeled. Thus, the first heavy rain kills these leaves and the storm sewers are clogged with debris. pic.twitter.com/biEj52RXQc

19:30 Tuesday PST:
Roads have already been closed in parts of California before the Great Winter Storm, including a section of Highway 1 near Big Sur. A 20-km section of the highway will be closed for at least two days between Mud Creek and Paul's Slide due to the risk of gullying and landslides, according to the California Department of Transportation.
Heavy snowfall will also travel through the Sierras Passes, such as the Donner Pass on Interstate 80.
Although unstable weather disrupts travel, it will contribute to efforts to fight forest fires across the state.
"This is good news to help minimize this shooting activity," Cal Fire spokesman Scott McLean said on Tuesday.
