The amount of snow blanketing the Sierra Nevada is even larger than the 2017 snowpack that pulled the state out of a five-year drought, California water officials said. As of Thursday, the snowpack measured 202% of average after a barrage of storms throughout winter and spring, according to the Department of Water Resources. The wet weather has slowed but not stopped, with thunderstorms prompting flash flood warnings Sunday in the central and southern parts of the state. At this time last year, the snowpack measured 6% of average — making this year 33 times bigger than 2018, the San Francisco Chronicle reported.
