A heavy winter storm overnight Wednesday and into Thursday caused Summit County to practically shut down. While the area saw a little relief by the end of the day and overnight as roads began to reopen, it’s not over yet. Another winter storm is on its way and should be moving into the county by this afternoon.

Summit County is again under a winter weather warning. According to the National Weather Service, another Pacific storm system will be moving over Colorado later today, bringing another round of snowfall to the northern and central mountains of Colorado. Snow is expected to begin falling by early afternoon and then continue overnight. It will also be possible that a few embedded thunderstorms may develop. Snowfall is expected to become moderate to heavy at times, with heavy snow most likely to hit Summit County this evening. Additional snowfall amounts of 6 to 12 inches are expected from this storm.

Gusty winds are expected to develop during the evening and overnight with gusts of 60 to 70 mph over the higher elevations. the increasing winds will cause poor visibility due to blowing and drifting snowfall.

Weather conditions will be best this morning, but will deteriorate later this afternoon and evening as snow begins to fall. Traveling into the mountains of central Colorado tonight should only be done if absolutely necessary, the National Weather Service alert warns.

This storm is the latest in a series of storms that has produced between 3 and 5 feet of new snow over the past week. Substantial snowfall led to historic avalanche conditions in Summit County, bringing extreme avalanche danger through much of the central mountains.

Numerous large avalanches have been occurring through the week, causing road closures at times. An avalanche hit Vail Pass at around 1:30 a.m. Thursday, dumping 6 feet of snow onto the roadway. At around 5 a.m. another avalanche between the water-treatment plant and Conoco gas-station complex near Copper Mountain ruptured a natural-gas line, closing off access to the area. At around 4 p.m., another giant avalanche hit CO 91 at mile marker 21, near Copper Mountain, spreading 15-foot-deep snow across 300 feet of roadway and trapping multiple cars

Tonight’s additional snowfall will keep avalanche danger in the high to extreme category through Saturday. Additional avalanches are expected over the next several days. The winter storm warning remains in effect from 2 p.m. this afternoon to 6 a.m. Saturday.
