Long Range Mountains, Corner Brook, Gros Morne, Northern Peninsula.

Watch for small pockets of wind slab if you are entering any steep gully features.

High

Avalanche Summary

No recent avalanches have been reported.

Snowpack Summary

The snow surface in exposed areas is likely hard and wind affected and soft powder in sheltered areas. There may be a thin sun crust on steep south facing slopes.

Snow depths in Long Range Mountains average about 80 cm in wind-sheltered areas and are much more variable in wind-exposed areas. The snowpack structure is strong and bonded.

Cornices have been forming along northeast-facing ridges.

Terrain and Travel Advice

  • Carefully evaluate steep lines for wind slabs.
  • Watch for wind-loaded pockets especially around ridgecrest and in extreme terrain.

Problems

Wind Slabs

Wind Slab avalanches are the release of a cohesive layer of snow (a slab) formed by the wind. Wind typically transports snow from the upwind sides of terrain features and deposits snow on the downwind side. Wind slabs are often smooth and rounded and sometimes sound hollow, and can range from soft to hard. Wind slabs that form over a persistent weak layer (surface hoar, depth hoar, or near-surface facets) may be termed Persistent Slabs or may develop into Persistent Slabs.
