Points saillants

Start on small slopes to test how well the recent snow has bonded.

If you find signs of instability, it may not be time to step out to steeper or more complex terrain.

    Strong west and southwest wind has redistributed recent storm snow. Avalanches will be most likely on leeward slopes and in cross-loaded features.

Confidence

Moderate

  • We are uncertain about how quickly the snowpack will recover and gain strength.

Avalanche Summary

On Sunday, several large (size 3) natural wind slab avalanches were reported in alpine terrain. Some may have stepped down to deeper weak layers.

On Saturday, southwest of Valemount, a few large (up to size 3) explosive triggered slab avalanches were reported.

If you are heading into the backcountry, please share any observations with the Mountain Information Network.

Snowpack Summary

Recent snow came with strong westerly wind. Expect to find small pockets of dense, reactive wind slab on leeward slopes.

Below that, 50 to 80 cm of settling snow overlies previously wind-affected surfaces in open terrain and / or a solid melt-freeze crust formed in early February.

A layer of surface hoar, facets, and/or crust from late January is buried around 140 cm. Triggering this layer is unlikely at this time.

The remainder of the snowpack is consolidated with no layers of concern.

Terrain and Travel Advice

  • Start with conservative terrain and watch for signs of instability.
  • Watch for signs of instability like whumpfing, hollow sounds, shooting cracks, or recent avalanches.
