Recent strong winds have formed windslabs in alpine and treeline areas,
Our snowpack is very sensitive to warming these days. Approach any open area, at any elevation with caution. Low angle terrain is key right now.
Recent strong winds have formed windslabs in alpine and treeline areas,
This layer is getting getting buried deeper and deeper over time. The weight and amount of new snow is slowly increasing, which will increase the size of any potential avalanches.
Nothing new was seen today, but we've had more reports of cracking and whumphing at all elevations/aspects.
Warmer temps promoted settlement in the upper snowpack on Saturday. Windslabs 10-30cm thick are still common places along lee features (E and N aspects) in the alpine and treeline with cracking and whumpfing observed by forecasters while travelling in high treeline and alpine areas common. The windslabs are failing on weak facetted grains that formed during last weeks cold snow. Deeper in the snowpack the Dec 5th crust persists and has been making travel easier. In thinner areas, triggering the weak crystals under the crust is a real possibility so avoid steep thin and variable features in the terrain.
Light to moderate SW winds tomorrow. Flurries giving a few cm's of snow and increasing temperatures. Daytime high of -2, but likely warmer as Mud Lake crept above the predicted high today.
