Regions

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

Watch for unstable snow on isolated terrain features - lingering pockets of wind slab in extreme terrain and steep sunny slopes becoming moist in the afternoon.

High

Avalanche Summary

In the past few days avalanche activity has been limited to small (size 1) wet loose avalanches on steep solar aspects and a few natural cornice failures that did not pull slabs on the slopes below.

If you head into the backcountry, consider sharing your observations on the Mountain Information Network!

Snowpack Summary

A crust exists on solar aspects up to 2000 m and on all aspects below 1800 m. Dry snow can still be found in the high alpine and on shady aspects between 1800-2000 m.

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.

Terrain and Travel Advice

  • Minimize exposure to steep, sun exposed slopes, especially when the solar radiation is strong.
  • 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

Loose Wet

Loose Wet avalanches are the release of wet unconsolidated snow or slush. These avalanches typically occur within layers of wet snow near the surface of the snowpack, but they may quickly gouge into lower snowpack layers. Like Loose Dry Avalanches, they start at a point and entrain snow as they move downhill, forming a fan-shaped avalanche. Other names for loose-wet avalanches include point-release avalanches or sluffs. Loose Wet avalanches can trigger slab avalanches that break into deeper snow layers.
