As a result of all the snow, an avalanche warning is in effect through Thursday for all of the Colorado backcountry areas in the northern and western mountains. It is recommended to avoid backcountry skiing and snowboarding during this period of time.

Snow has fallen upwards of 20 inches in the mountains of Colorado. Snow is forecasted to wrap up Wednesday night as many travel for Thanksgiving.

A “major winter storm” will hit Colorado’s mountains Monday night, make its way to lower elevations Tuesday evening and last through Wednesday, NWS forecasters said.
