La Niña expected to bring ‘extreme’ weather patterns statewide, head climatologists says

MENDOCINO CO., 10/1/25 – As Northern California’s rainy season quickly approaches, meteorologists are anticipating “extreme” weather events to hit the state for the rest of 2025.

“Expect extremes, so dry periods interrupted by large and long-lasting atmospheric river conditions,” said state climatologist Michael Anderson during a virtual discussion Tuesday hosted by the state’s Department of Water Resources. DWR monitors the state’s water supply and oversees the construction and maintenance of dams.
