Highlights

Keep a close eye on the depth of new snow as you gain elevation. The fresh storm slab will take time to stabilize.

Avalanche Summary

No recent avalanche observations have been reported but new snowfall received on Friday has created fresh storm slabs at higher elevations in the South Coast mountains. Any rainfall on new snow at lower elevations may create loose wet avalanches on steeper terrain. If you have been out in the mountains, please submit your observations to the Mountain Information Network (MIN).

Snowpack Summary

15-20cm of new snow has formed fresh storm slabs in alpine and treeline elevations. Rain is beginning to saturate this new snow at lower elevations. At higher elevations, the new snow overlies existing storm slabs which are rapidly strengthening. 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.
