Atmospheric river dumps snow and record rain on California

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.
