Kernpunkte

It will be possible to trigger an avalanche large enough to bury, injure, or kill you today in steep terrain. Poor structure is widespread in Togwotee and slabs of 1 to 2 feet sit on weak snow. Avoid steep, rocky slopes and areas drifted by the wind. Identify creek beds and terrain traps as you ride, and look for sheltered slopes less than 30° for the best and safest riding.

    Weak, faceted snow is widespread at the base of the snowpack. A slab of up to 2 feet sits on this weak layer, thicker in wind-loaded areas. This problem is most pronounced on west through north through east aspects in areas where the slab is thinner, and you are more likely to impact the weak snow below. Snow from the recent storm added a significant load to the snowpack, and it continues to adjust. Yesterday, a rider observed a small remotely triggered avalanche on a steep rollover. Watch for steep rocky slopes, unsupported convexities, and areas near wind-drifted features. You may not see signs of unstable snow (collapsing and cracking), but I bet you will find weak facets if you dig down. The consequences of triggering an avalanche remain high, particularly around road cuts and creek beds where even small avalanches can bury you.

    Togwotee could receive 3 to 5 inches of new snow by this evening, and winds out of the SW could gust up to 30 mph. This will continue to load an already weak snowpack, especially in areas exposed to the wind.

Avalanche Discussion

Moderate avalanche danger does not mean it is time to step out on to bigger, steeper slopes. Large avalanches - big enough to bury, injure or kill you - are still possible in the areas mentioned above. Stepping the avalanche danger down from considerable to moderate is an indication that it is becoming less likely to trigger an avalanche as the snowpack adjusts.  Weak layers remain widespread, and we continue to see propagation in test pits. The problem still exists and you are still rolling the dice if you venture into steep terrain. Consider the consequence if the slope you want to ride avalanches and remember that tracks are not always a sure sign of stable snow.

HAPPY NEW YEAR!!!
