Avalanche Summary

Small wet loose avalanches (size 1) have been reported out of steep south and west facing slopes. More wet loose activity can be expected with sustained warming this week.

Snowpack Summary

Warm temperatures are rapidly settling the snowpack. Expect widespread melting of the surface snow, especially on south-facing slopes. Crusts may form overnight, but will melt quickly in the mornings. Lingering wind slabs may be found in the alpine, but are trending towards being unreactive. The snow has formed a strong bond to the late November rain crust which is now 30-50 cm deep. Treeline snow depths are approximately 1 m throughout the region.
