Make continuous observations of the depth and reactivity of new snow as it stacks up. Be ready to dial back your terrain selection when you see signs of instability.

Terrain and Travel Advice:
  • Watch for newly formed and reactive wind slabs as you transition into wind affected terrain.
  • Wind slabs are most reactive during their formation.
  • Small avalanches can have serious consequences in extreme terrain. Carefully evaluate your line for wind slab hazard before you commit to it.
Wind Slab

New wind slabs will begin to form as light to moderate snowfall combines with strong south winds. Weak snow grains and a hard crust in the upper snowpack suggests there may be a possibility for some slabs to fracture deeper than expected.

Avalanche Summary

A skier accidentally triggered an small (size 1) wind slab on Friday in the Beaufort Range. Check out this MIN for the details. It is a good reminder that a problematic layer exists below some wind slab formations that has kept them surprisingly sensitive to triggering. Reports have otherwise been quiet.

Looking forward, concerns shift to new snow accumulations under elevated winds for Wednesday.

Snowpack Summary

10-20 cm of new snow should accumulate at higher elevations by end of day Wednesday under strong southeast winds. It will add to a rapidly settling 5-10 cm of snow from Sunday.

The new and recent snow is burying a variety of surfaces, including crust on sun-exposed slopes, old wind slabs, and up to 20 cm of old, soft, faceted snow in sheltered north-facing terrain. It's uncertain as yet whether new wind slabs may be capable of fracturing deeper than expected where they overlie this faceted snow.

The mid and lower pack contains deteriorating old crusts and storm layers that are now for the most part dense, homogenous, and moist.

Below treeline, most areas are below the threshold for forming avalanches.
