Kernpunkte

 Dangerous avalanche conditions will exist by the end of the day as snow and wind move in to the mountains. It will become likely that the weight of a rider will trigger an avalanche on steep, wind loaded slopes. Avalanches failing within today’s snow could break deeper and wider into older snowpack layers. Avoid being on or underneath steep, rocky, wind loaded slopes

Yesterday a report came in that a skier triggered avalanche occurred south of Teton Pass in steep terrain resulting in a partial burial. Teton County Search and rescue responded to the incident. No further information is available at this time.

    As snowfall rates and wind increase, fresh slabs will begin to form on leeward slopes. These avalanches will be easy to trigger by the end of the day. A wind slab avalanche could break into buried November weak layers, propagating wider and deeper than expected. As the storm moves in, pay attention to where the wind is moving snow and avoid those areas if fresh wind deposits lie on a steep slope.

    Additional weight from today’s storm will continue to stress buried weak layers that formed in November. It is possible for a rider to trigger a persistent slab avalanche that is large enough to bury or injure someone. The best way to avoid this problem is to avoid being on or underneath steep, rocky, wind loaded slopes. Collapsing and cracking on the snow surface are obvious signs of instability.

Avalanche Discussion

Since yesterday, we have received reports of multiple natural avalanches. The snowpack does not like rapid change, and over the last week Togwotee has received almost 2 feet of snow with 3 inches of snow water equivalent (SWE), strong winds, and fluctuating temperatures. Today the pattern continues, with additional snowpack stressors on the way. For the time being, it is best to give upper elevation and shaded mid elevation slopes that have a persistent weak layer, some space and stick to lower angle terrain.

If you are out and about and see recent avalanches, cracking, collapsing or anything snow related, please consider submitting an observation. Thanks to those who have submitted recently!
