Regions

Northwest Inland, Kispiox, Microwave-Sinclair, Ningunsaw, Ningunsaw, South Bulkley, South Bulkley, Telkwa.

As the sun shines over the next few days be aware of recent new snow sluffing in steep terrain facing the sun during the warmest part of the day.

Avalanche Summary

Avalanche activity over the past week has been limited to small wet loose avalanches and cornice falls during periods of warm sunny weather.

Snowpack Summary

A dusting of new snow has fallen on moist or crusty snow layers, except shaded terrain above roughly 1400 m where the snow has remained dry over the past week. The middle of the snowpack is strong and contains numerous hard crusts. The lower snowpack is composed of weak basal facets. There hasn't been avalanche activity on it recently, but it will remain on our radar this spring as it may become active with abrupt changes to the snowpack, such as rapid loading (heavy snowfall or rain) or prolonged warming.

Weather Summary

Terrain and Travel Advice

  • Watch for wind-loaded pockets especially around ridgecrest and in extreme terrain.
  • Avoid shallow, rocky areas where the snowpack transitions from thick to thin.

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.
