In sintesi

Low hazard does not mean no hazard. The chance for skiers and riders to trigger shallow wind slabs and loose snow sluffs will slowly increase during the day as new snow accumulates. Avoid high consequence terrain where even small slides could sweep you over cliff bands or down steep, sustained couloirs.

    As the day progresses, new snow combined with westerly ridgetop winds will begin to build isolated pockets of wind slab in exposed, leeward terrain at the upper elevations. These slabs will form on good sliding surfaces, which include sun crusts and surface hoar. Backcountry travelers venturing in to very steep, wind loaded terrain could trigger these slabs to depths of six to twelve inches by this evening.

Avalanche Discussion

Expect partly to mostly cloudy skies on Tuesday ahead of a weaker system slated to move into the area Tuesday afternoon, which will bring increased cloud cover and scattered snow showers. Overnight lows in the mountains will be in the low to mid teens before rising into the mid to upper 20s during the day. Westerly ridgetop winds will range from 15 to 25 miles per hour.The General Avalanche Hazard is expected to be LOW in the Tetons on Tuesday. Backcountry travelers venturing into very steep, wind loaded terrain could trigger isolated pockets of wind slab four to eight inches deep. On sunlit slopes, any extended periods of sunshine will make these slides more susceptible to failure and bring about the possibility for sluffing of the new snow. In the Togwotee Pass and Greys River areas, persistent slabs up to three feet deep still pose a threat to skiers and riders in very steep, avalanche prone terrain. There, the General Avalanche Hazard will remain MODERATE.
