Kernpunkte

Mountain temperatures are starting out around 15 degrees cooler than yesterday. While a few snow showers could linger in the morning hours, sunshine will be the primary factor impacting the avalanche hazard. As the day warms above 7,500 feet, the chance for skiers and riders to trigger small to large wind slabs will be on the increase, and shedding of the new snow could occur naturally on sunlit aspects. Daytime warming and sunshine could also bring about the possibility of wet slides involving the new snow on sun affected slopes. Monitor the effect of the sun, and transition to shaded terrain if snow surfaces start to become damp. Below 7,500 feet, significant avalanche activity is unlikely.

    Around a foot of snow has fallen since midnight on Wednesday. Strong southwesterly to westerly ridgetop winds accompanied this snowfall, and dense wind slabs up to two feet in depth have formed on leeward slopes in the mountains. These wind slabs could be triggered by backcountry travelers in steep avalanche terrain, and the resulting avalanches could entrain significant amounts of snow and travel long distances. Warming temperatures and sunshine will increase the likelihood of triggering these slabs, and natural activity might be possible on sunlit aspects in the afternoon.

Avalanche Discussion

( Discussion is generated from the previous day's afternoon forecast. )Expect light to moderate snowfall overnight as an upper level disturbance moves over the region before a drying trend begins in the morning. As the day progresses, cloud cover will decrease and periods of sunshine will be possible in the afternoon. Overnight lows in the mountains will be in the low teens before rising into the low 20s during the day.The general avalanche hazard is expected to be Considerable in the Tetons above 9,000 feet. There, skiers and riders could trigger newly developed wind slabs up to 30 inches deep in steep, avalanche prone terrain. Less substantial snowfall in the mid elevation terrain in the Tetons, and in the Togwotee Pass and Southwest Trails areas, will result in Moderate hazard with smaller and less reactive avalanche activity. With possible sunshine in the afternoon, shedding of the new snow could develop on sunlit aspects. Monitor the effect of the sun, and transition to shaded terrain if snow surfaces start to become damp.
