The snowpack in the Sierra Nevada mountains has reached record-breaking levels thanks to the deluge of snow smashing California this week.

According to data from the California Department of Water Resources (CDWR), the Southern Sierras—from San Joaquin and Mono counties to Kern county—currently have a snowpack 257 percent greater than the average for this time of year, and 247 percent larger than is average for the usual snowpack peak on April 1.
