An atmospheric river from the tropics brought 43 days of rain to the U.S. states of California, Utah and Oregon as well as the Mexican state of Sonora. It was the worst disaster ever to strike California; the state's Central Valley was effectively an inland sea for months afterwards. State government temporarily moved to San Francisco because the capital, Sacramento, was under 10 feet (3.3 m) of water; the damage and the ensuing shortfall in tax revenues nearly bankrupted the state.
