MAMMOTH LAKES, CALIFORNIA - MARCH 28: A person walks with a dog as a vehicle drives while snow falls in the Sierra Nevada mountains from yet another storm system which is bringing heavy snow to higher elevations while further raising the snowpack on March 28, 2023 in Mammoth Lakes, California. The Pacific storm is delivering widespread rain and mountain snow to the U.S. west coast in Northern California and Oregon. After years of drought, the state snowpack average for California may hit an all time record from the several feet of new snow expected to fall during the storm in parts of the Sierra Nevada mountains.
