Rising freezing levels and clear skies are creating heightened avalanche danger on steep slopes.
Approach steep slopes with caution and back off if the surface becomes moist.
Wind slabs formed on most aspects at treeline and above continue to remain active. Human-triggered wind slabs remain possible and are more likely in open terrain features on north facing terrain features.
Freezing levels will rise to 2200 m throughout the day and are coupled with sunny skies. Cold surface snow will become moist specifically on steep south facing terrain features.
Several human triggered size 1 to 1.5 wind slabs were reported on Saturday. These avalanches were mostly in open terrain features and steep terrain near ridge lines.
Various surfaces of moist surface snow on steep solar facing slopes, and settling dry and wind affected snow on north facing slopes can be found.
This overlies a heavily wind affected snowpack over the December 16th crust that is roughly 120 to 150 cm deep.
In deeper snowpacks above 2200 m a crust formed mid-November, can be found near the ground.
