After a dry start to California’s winter rainy season, a series of big storms that began around Thanksgiving delivered enough snow for the Sierra Nevada to begin 2020 in relatively good shape.

As of Dec. 31, the statewide Sierra Nevada snowpack — a major source of California’s water supply — stood at 94% of its historical average.

That’s the highest total in four years, when it came in at 106% on Dec. 31, 2015.
