Over the previous few days snow has fallen on the Tetons above 8000 ft.  With the fresh coat of snow and cold temperatures, early winter conditions will remain and probably carry into the actual beginning of winter.  All alpine areas will have some snow, ice, and verglas.

SNOW AND ICE IN THE MOUNTAINS-SEPTEMBER 21, 2019

The first of several storm systems impacted the Tetons during the first week of September.  Since then, significant snow fall has continued above 10,000 feet. Expect to find much more challenging winter conditions on the Grand and other high peaks. If hiking or backpacking in the mountains it's that time of year to be prepared for much wetter and colder conditions.
The days are getting shorter and the temperatures are falling. Be sure to pack plenty of extra layers and a headlamp.

CHANGING SEASONS - SEPTEMBER 6, 2019

After a sunny, dry Labor Day weekend in the Tetons, the weather is subtly changing at higher elevations with the potential for rain and snow in the forecast during this upcoming week. As temperatures dip at night, look for recent precipitation to form icy conditions on previously dry routes throughout the mountains, specifically on popular climbs on the Grand Teton such as the Owen-Spalding route and other shadier aspects of the high peaks. Fall is on its way.
