A series of supercharged storms that blasted the Sierra in March has bolstered the snowpack that was alarmingly low before the start of the month. The National Weather Service (NWS) in Sacramento tweeted Saturday that the water content of the snowpack has more than tripled in the past month. On Feb. 22, an average of 4.6 inches was measured and on March 23 an average of 15.5 inches was recorded, going from 16 percent to 56 percent of the April 1 average.
