Live updates: Evacuations ordered, roads closed in California as flooding rain arrives
Heavy rain and mountain snow is spreading across California and will bring the risk of flooding, mudslides and travel delays into Friday.
Measurable rain is expected in the state's largest cities, including in Los Angeles, San Diego, San Francisco and Sacramento.
Mandatory evacuations have already been issued for people living near the Holy Fire burn scar due to the potential for flooding and mudslides, while those in Malibu near the Woolsey Fire burn scar have been put on alert for potential evacuation.
"Donner Pass could be measuring snow in feet by Friday morning, and it's not out of the question that the pass would need to be shut down for a time Thursday into Thursday night, when the bulk of the snow is expected to fall there," said AccuWeather Meteorologist Jake Sojda.

While rain showers are just starting to move into the Los Angeles area, heavy rain has been inundating areas farther north for several hours.
Because it hasn't rained heavily in so long, trees still haven't been de-leafed. So the first big rain knocks those leaves down, and storm drains everywhere are clogged by debris. pic.twitter.com/biEj52RXQc

7:30 p.m. PST Tuesday:
Road closures have already begun in parts of California ahead of the major winter storm, including a stretch of Highway 1 near Big Sur. A 12-mile stretch of the road will be closed for at least two days between Mud Creek and Paul's Slide due to the potential for washouts and mudslides, according to the California Department of Transportation.
Heavy snow will also make travel through mountain passes in the Sierras, such as Donner Pass along Interstate 80.
While the unsettled weather will disrupt travel, it will help wildfire efforts across the state.
"This is good news to help minimize that fire activity," Cal Fire spokesman Scott McLean said on Tuesday.
