Another round of heavy snow will spread across western Colorado from Wednesday night to Friday morning, according to the National Weather Service. Some areas could see up to 14 more inches from the Pacific storm system. Mountain valleys could get up to 6 more inches, forecasters said.

The heaviest periods of snow are expected to be Wednesday and Thursday evenings.

Three rounds of heavy snow have already improved snowpack levels dramatically in the Colorado high country. On Nov. 26, snowpack in northwest Colorado was 48 percent of its 30-year average for the date. On Dec. 20, before receiving another 12 inches on Christmas Eve and Christmas Day, the snowpack was at 75 percent of average, according to the Natural Resources Conservation Service in Lakewood.
