Points saillants

Storm snow is incrementally loading a weak layer.

Expect reactive storm slabs where there is more than 20 cm of snow over surface hoar or crusts.

    Low density storm snow will continue to incrementally load a weak layer buried in late January. Where storm snow amounts are greater than 20 cm, storm slabs are possible, elsewhere dry loose is more likely.

Terrain and Travel Advice

  • Be aware of the potential for loose avalanches in steep terrain where snow hasn't formed a slab.
  • Be aware of the potential for larger than expected storm slabs due to buried surface hoar.
  • Be aware of the potential for human triggerable storm slabs at lower elevations, even on small features.
  • Continue to make conservative terrain choices while the storm snow settles and stabilizes.

Confidence

Moderate

  • We are uncertain due to a highly variable snowpack.

Avalanche Summary

On Monday, several dry loose size 1 to 1.5 avalanches were reported.

Going forward, low density storm snow will likely release as dry loose avalanches, slab formation is possible in areas that receive over 20 cm of storm snow.

Snowpack Summary

Low density storm storm, up to 20 cm continues to bury a weak layers in the upper snowpack.

Weak layer depths and distribution are variable, but there are two prominent layers:

  • A facet/crust layer buried at the end of January is down roughly 30 to 50 cm.

  • A surface hoar/crust layer buried early to mid February depending on location down 15 to 20 cm.

Avalanche activity on these layers has been limited and is generally small with releases where wind loading has buried them slightly deeper.

Cutbanks and sheltered below treeline terrain are suspect places to trigger these layers where they are buried over 30 cm deep.

Below this, the mid and lower snowpack are well settled with several layers of crust
