From late December 2022 through mid-January 2023, California was hit by repeated storms fueled by torrents of moisture called atmospheric rivers. Climate change likely made the storms more intense with lower pressure and higher precipitation. The storms brought a wide variety of hazardous weather to the Bay Area and California's Central and Northern Coasts, leading to flooding, storm surge, and strong winds. Climate change is fundamentally “loading the dice,” increasing the chance for intense storms like these to form, ultimately leading to a growing risk of property damage and loss of life.
