Tetons

Strong southwesterly ridgetop winds scoured windward slopes and added some new load to leeward aspects. At the mid and upper elevations, backcountry travelers venturing into very steep terrain with a base of faceted snow might be able to trigger dense slab avalanches up to two feet deep in areas that have not seen recent avalanche activity. The snowpack is mostly stable at the lower elevations and avalanches are unlikely.

Cold air aloft and a Pacific trough will bring a chance for light snow showers tonight through Monday. Overnight lows in the mountains will be near zero before rising into the upper single digits during the day. Westerly ridgetop winds at 20 to 30 miles per hour will decrease to 10 to 20 overnight.The general avalanche hazard is expected to be MODERATE on Monday. Backcountry travelers venturing into very steep terrain that has not seen recent avalanche activity might be able to trigger dense slab avalanches to depths of two feet. With cold temperatures, decreasing winds and only a few inches of new snow in the forecast, new snow avalanches are not expected to be a concern. However, if snowfall amounts are greater than forecasted and strong winds continue, use caution on steep, newly wind loaded slopes.
