Highlights

Warm temps and strong sun will cause cornices to fail and initiate wet loose avalanches.

Expect these larger triggers increase the likelihood of releasing the persistent slab.

Avalanche problems

  • Wind Slabs

    • Alpine
    • Treeline
    • Below treeline
    Likelihood
    Possible
    Size
    1–2

    Up to 20 cm of recent snow has formed slabs in wind-loaded areas at upper elevations. These slabs have been most reactive where they overlie a crust.

  • Persistent Slabs

    Size

    Very large natural persistent slab avalanches have recently been reported, primarily on northerly aspects in the alpine.

    Wet loose avalanches are likely on steep solar slopes when the sun is strong.

Snowpack Summary

On the surface, up to 30 cm of recent snow exists on northerly aspects in the alpine. Solar aspects and lower elevations will sport a crust or moist snow.

Below this, a 5 to 25 cm variable strength crust from last week's rain event is present. This is capping a moist upper snowpack.

The primary weak layer of concern is a surface hoar, facet, and crust layer from early March, buried 60 to 120 cm deep.

The lower snowpack is generally well-settled and strong in most areas.

Terrain and Travel Advice

  • Cornice failures could trigger large and destructive avalanches.
  • The more the snowpack warms up and weakens, the more conservative your terrain selection should be.
  • Avoid steep, rocky, and wind-affected areas where triggering slabs is more likely.
