Highlights

The avalanche danger is Low in the majority of terrain today. In steep terrain above 9,000 feet the danger is Moderate. On steep, generally north facing slopes it is possible to trigger avalanches on weak layers buried 1-2 feet deep. While the likelihood of triggering these avalanches is low the consequences are high. Look for this avalanche problem type by digging down to check for loose, sugary snow grains. Cornices are also beginning to weaken as temperatures rise so consider the impact of a cornice fall above you. Practice safe travel techniques such as traveling one at a time, moving between islands of safety and communicating your plans clearly in order to minimize your group’s exposure to these hazards. Below 9,000 feet the danger is Low. In the lower elevations expect shallow wet loose avalanches in steep terrain in the afternoon.

    January and February were dry months. During this time weak layers formed throughout the forecast area. In the month of March a series of storms slowly built up slabs that have the potential to activate those weak layers. These weak layers are between 1-2 feet deep. While there has been only minimal activity on these layers, the potential exists. This avalanche problem is more likely to be encountered in steep upper elevation terrain on the north half of the compass and in terrain that avalanched in early January.

Avalanche Discussion

( Discussion is generated from the previous day's afternoon forecast. )Gradual warming from the high March sun will test the strength of the snowpack this week. Sun and slightly warmer temperatures tomorrow could lead to further small wet loose avalanches and perhaps some cornice failures. Larger or more dangerous avalanches one to three feet thick could be triggered tomorrow where a slab sits over the weak January layer, either on a repeater or an area with a thinner snowpack. Human triggered avalanches of this type will remain possible at upper elevations in the Southwest Trails area as well as the Tetons. Both areas will remain Moderate at upper elevations due to concerns with this weak layer. Avalanches in Togwotee Pass have become unlikely so expect Low avalanche danger there. In all lower and middle elevation zones and even some sunny aspects or rocky areas at upper elevations, expect small, wet avalanches and be wary of cornices overhead.
