Heavy snowfall replenishes Sierra Nevada mountains

Dangerously low snowpack levels in the Sierra Nevada mountains are getting a much-needed boost. Heavy snowfall has also closed highways and even closed down some ski resorts during blizzard conditions.

Officials with the University of California Berkeley's Central Sierra Snow Laboratory on Monday said recent snowfall broke the snowiest December record of 179 inches, set in 1970. The record is now more than 200 inches, with three days still to go.
