In sintesi

Carefully assess for wind slab as you travel.

Wind slab may exist on all aspects and elevations due to variable strong wind over the past few days.

Problemi valanghivi

  • Wind Slabs

    • Alta quota
    • Limite del bosco
    • Sotto il limite del bosco
    Probabilità

    Dimensione
    1–2

    Wind slabs have formed over hard, old snow and facets that they likely won’t bond well to.

    Wind has come from a variety of directions. Wind slab could exist on all aspects but The largest and most reactive slabs will be on north and east slopes.

Confidence

Low

  • We are uncertain due to the variability of wind effect on the snowpack.
  • We are uncertain due to a limited number of field observations.

Avalanche Summary

No recent avalanches have been reported.

Reports in this region are limited, please post any photos or observations to the MIN if you head out.

Snowpack Summary

Up to 30 cm of previous storm snow has been variably distributed, wind loading and scouring could be found on any aspect. This snow overlies old wind pressed snow and facets.

A layer of facets or a crust, from mid February,  may be found down 20 to 60 cm. This layer is more prominent at Haines Pass.

The late January crust is buried 50 to 100 cm deep. Below 1350 m. Surface hoar may linger above this layer on sheltered north to east aspects. This layer is more prominent on the inland side of the White Pass.

Facets or depth hoar exist at the base of the snowpack and may be a concern in the inland side of the region where the snowpack is shallower.

Terrain and Travel Advice

  • Watch for newly formed and reactive wind slabs as you transition into wind-affected terrain.
  • Recent strong wind means wind slabs may be found farther downslope than expected.
  • Recent wind has varied in direction, so watch for wind slabs on all aspects.
