Snowpack Summary

New snow over Tuesday night and Wednesday have added to storm slabs at higher elevations, which are especially deep and touchy on leeward slopes and in exposed areas. Total snowpack depths are likely around 160cm at treeline and over 2 metres at higher elevations. Aside from instabilities in storm snow, warm temperatures are promoting rapid settlement and strengthening of the snowpack.
