Tetons

At the mid and upper elevations areas of unstable snow persist on some steep slopes that frequently avalanche. Poor snow structure exists in areas where the snowpack is less than three feet deep. In these areas recent new snow lies upon a base of well-developed depth hoar. Persistent weak layers continue to be a problem in areas where the snowpack is deeper. Large avalanches that resulted in injuries have been triggered by skiers on these problem layers. Steep rocky chutes, couloirs and terrain with consequences are places for serious accidents. Avalanches are unlikely at the lower elevations.

On Saturday, a minor disturbance will move through the region and bring light snowfall. Overnight lows in the mountains will be near zero before rising into the mid-teens during the day. Westerly ridgetop winds will range from 10 to 20 miles per hour.The general avalanche hazard is expected to remain Moderate above 7,500 feet on Saturday. Up there, persistent slab avalanches with depths of one to three feet remain a threat to backcountry travelers in steep, avalanche prone terrain. Be skeptical of the snowpack. Great skiing and riding can be found on safe, low angle slopes. If you choose to travel into high consequence terrain, expert snowpack evaluation and route finding skills will be mandatory. Avalanche activity is unlikely below 7,500 feet.
