A rare setup for November will unleash two waves of heavy rain across California, with the second storm threatening to bring major flooding, mudslides, and travel chaos to Los Angeles and surrounding areas.
A two-part storm system is expected to bring rounds of heavy rain to California later this week and into the weekend. The second wave could produce rainfall amounts typically seen over several months in Southern California, resulting in significant travel disruptions, flash flooding and debris flows.
“The combination of a complex storm structure, a pronounced dip in the jet stream and abundant Pacific moisture is forecast to bring widespread drenching rain and drought relief to California,” AccuWeather Chief On-Air Meteorologist Bernie Rayno said. “Unlike the typical pattern where heavier rain impacts Northern California, this system is expected to bring the most significant rainfall to coastal areas of Southern California, including Los Angeles.”

The heaviest rain is forecast for San Francisco from Wednesday night to Thursday, while Sacramento will experience rounds of rain from Thursday to Thursday night. Both areas are expected to receive 1-2 inches of rain from the storm.
