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 large to very 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.

    Close to two feet of snow has fallen since midnight on Wednesday. Strong southwesterly to westerly ridgetop winds accompanied this snowfall, and dense wind slabs up to three 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

Expect skies to continue to clear overnight before partly to mostly cloudy skies return in the afternoon. Overnight lows in the mountains will be in the low teens before rising to near 30 during the day. Northwesterly ridgetop winds will back to the west at 10 to 20 miles per hour.In the higher elevations on Saturday, the general avalanche hazard is expected to be Considerable in the Tetons, and Moderate in the Togwotee Pass and Southwest Trails forecast zones where less snow has accumulated since early Thursday morning. The chance for skiers and riders to trigger large slab avalanches will be on the increase as temperatures warm and the sun heats the surface of the snowpack, and natural activity could become possible. These slides could range from two to four feet in the Tetons and be up to two feet in the other two forecast areas. As the day warms, both wet slabs and wet loose slides involving the recent snowfall could release naturally on steep, sunlit slopes. Don’t let recent snowfall, sunshine or the weekend timeframe impair your judgement. Monitor warming temperatures and the impact of the sun, and have a plan to transition to shaded terrain when snow surfaces start to become damp. Significant avalanche activity is unlikely at the lower elevations.
