Snowpack Summary
Areas around Terrace have seen as much as 60 cm recent storm snow. Winds have shifted from southwesterly to northwesterly. A pre-Christmas layer of surface hoar was previously buried on or around December 22, and is now buried 50-80 cm below the surface. It is unclear how reactive this layer is, but its presence could increase the potential size of avalanches from the recent storm snow.Lower in the snowpack, sitting somewhere between 120-200 cm below the surface lies a weak layer from mid-December. This layer was initially a concern when snowfall first accumulated, but the strength of this layer has generally improved. The surface hoar was most prevalent and has most recently been reactive between 1100-1300 m in more northern portions of the region, something to keep in mind if you plan to travel to areas like Ningunsaw.
