In sintesi

Recent storm snow (in excess of 1 m deep!) will take some time to settle and stabilize. Stick to conservative terrain in the meantime.

Avalanche Summary

During the storm earlier this week, a widespread storm slab avalanche cycle was reported to size 2 in most areas (size 3 in Bear Pass). Natural activity has tapered since Wednesday.

Snowpack Summary

Over 1 m of new snow fell earlier this week. Various temporary interfaces may exist within the storm snow due to wind and temperature changes through the storm.

In some areas, the recent snow may sit on a layer of small surface hoar crystals in sheltered terrain. A well bonded crust may be found in the mid snowpack below 1400 m.

In general, this season's upper elevation snowpack is shaping up as the ideal coastal snowpack; deep, strong and uncomplicated. Snowpack depths in excess of 300 cm can be found at treeline elevations.
