Rider triggerable wind slabs can still be found on north and east aspects at upper treeline and in the alpine.
Continuously assess conditions as you move through terrain.
Where the snow surface is dry small wind slabs may exist , where it’s wet loose avalanches are possible.
Rider triggerable wind slabs can still be found on north and east aspects at upper treeline and in the alpine.
Wet loose avalanches are possible on steep terrain when the snow surface feels slushy or wet.
On Monday a few small cornice triggered wind slabs were reported.
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.
Surface snow is variable, on steep solar facing slopes moist snow is expected and on north facing slopes, at treeline and above, 15 to 30 cm of dry, wind affected snow can be found.
This overlies a heavily wind affected snowpack over the December 16th crust that is generally 100 to 150 cm deep. This crust may be on the surface on scoured south facing alpine features.
In deeper snowpacks above 2200 m a crust that formed in mid-November, can be found near the ground.
