Turnagain Pass Avalanche Forecast
The avalanche hazard is MODERATE above treeline today. Steep slopes on a variety of aspects above treeline should be treated with caution. Large triggers such as snowmachines or groups of riders will increase the chances of triggering slabs up to 2 feet in depth. Below treeline (especially below 1,800′) the avalanche hazard is LOW, where the snowpack is capped by a thick crust.
The snowpack around Turnagain Pass is not typical for this time of year. November and December were dry months with close to record lows in terms of snowfall. Clear and cold conditions helped to weaken the snow that was sitting on the ground. This is what comprises the foundation of the snowpack.
The New Year brought the first significant storm of the season. This storm started warm & wet and finished cool & dry. This is what we call a “right side up” storm. This newest snow has since bonded well to the old snow surface.
Despite this, we still have that weak snow lurking deeper in the snowpack. It will be possible to get onto slopes without seeing the normal warning signs of shooting cracks or experiencing collapsing. This is a tricky set up that requires conservative travel practices and digging/testing the snow below the surface.
It will be generally difficult to initiate an avalanche today. However, the possibility still exists for humans to trigger an avalanche in deeper layers, especially in steep terrain.
