An atmospheric river swept through Northern California, dumping record rain and deep snow in the region. In Santa Rosa, the rainfall shattered a three-day record of about 10 inches set in October 2021.
The weather event occurs when water evaporates into the air and is carried along by the wind. It followed a bomb cyclone that hit the US Pacific north-west and killed multiple people.
BBC Weather has reported that the atmospheric river will continue to move eastwards.
