Record-breaking snowfall in California's Sierra Nevadas.

California's snowpack has reached a record high due to 17 atmospheric rivers and other storms that have hit the state since December. The water stored in the snowpack is 235% of normal, surpassing the previous record set in 1982-83. Ski resorts in the Sierra Nevada have seen unprecedented snow totals, with Mammoth Mountain recording its snowiest season on record. The vast amount of snow and heavy rain has significantly reduced the state's drought. However, concerns are now turning to the prospect of warmer temperatures that could cause flooding as the spring wears on.
