The eastern Sawatch Mountains and western Mosquito Range of Colorado will be whitened by snow above 11,000 feet with the heaviest snow expected above 12,000 feet. The Sawatch Mountain Range is home to the highest mountain in the Rockies, Mt. Elbert, which is around 14,440 feet in elevation.
Snowfall amounts of 4-8 inches are expected with local accumulations of 10 inches predicted in the highest elevations.
