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.
