    New snow and wind are forming fresh and reactive slabs. Wind-loaded deposits may be deeper than expected due to availability of pre-existing snow for redistribution by wind.

Avalanche Summary

During the storm earlier this week, a widespread storm slab avalanche cycle was reported to size 3. Natural activity has tapered dramatically since the end of the storm on Wednesday.

Snowpack Summary

A new storm arrives with heavy snowfall and strong wind. It falls over a hefty dose of storm snow from earlier this week.

In some areas, the recent snow may have buried a layer of small surface hoar crystals over 1 m deep 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.

Terrain and Travel Advice

  • Use increased caution at all elevations. Storm snow is forming touchy slabs.
  • Minimize exposure during periods of heavy loading from new snow and wind.
  • As the storm slab problem worsens, the easy solution is to choose more conservative terrain.
  • Choose low-angled, sheltered terrain where new snow hasn't been wind-affected.
