Thousands of people are facing up to 10 inches of snowfall as one of the first major winter storm systems of the season hits the Rockies. The National Oceanic and Atmospheric Association released a winter weather advisory for parts of Colorado and Wyoming on Tuesday, September 23rd, warning of wet snow accumulations reaching up to 10 inches.

Winter Weather Advisory

In Colorado, 4-10 inches of snow are expected along the high mountain passes in and around Rocky Mountain National Park, the Medicine Bow Range, the Mosquito Range, the Indian Peaks, and the mountains of Summit County. A foot or more could land on some of the highest peaks along the front range. Meanwhile valley areas including the towns of Silverthorne and Winter Park can expect little to no snow accumulation throughout the storm.

Snow accumulations in Wyoming are expected to be slightly less, with 4-8 inches of snow above 8,500 feet in the Snowy Range. The National Weather Service forecasts lower snow accumulations for areas below 8,500 feet. Both alerts are in effect until 6pm on the evening of Tuesday, September 23rd.

Preparing For Snow

The winter weather is expected to impact roads, creating slippery and slushy conditions along higher mountain passes impacted by the storm. Drivers should slow down and use caution. Allow extra time to reach any destination safely. The first winter storm of the season is often among the most hazardous, so be prepared.
