In this photo provided by Mammoth Mountain Ski Area, MMSA, a snow plower removes snow in Mammoth Mountain in Mammoth Lakes, Calif., early Wednesday, Dec. 15. Another storm is pushing into California as the state cleans up from a powerful weather system that coated mountains with much-needed snow and set rainfall records in the drought-stricken state. Wednesday's storm is expected to mostly impact Northern California.
