Highlights

Recent storm snow may take a bit more time to stabilize.

Avalanche problems

  • Persistent Slabs

    • Alpine
    • Treeline
    • Below treeline
    Likelihood
    Unlikely - Possible
    Size
    2–3

    It remains possible that riders could trigger surface hoar and/or faceted grains that were buried mid-February, especially at high elevations where a thick crust doesn't exist above it.

  • Storm Slabs

    • Alpine
    • Treeline
    • Below treeline
    Likelihood
    Possible - Likely
    Size
    1.5–2.5

    All the recent snow may take a bit more time to stabilize. This is particularly true where it overlies weak surface hoar crystals and in wind-exposed lee features.

Avalanche Summary

We did not receive any new reports of avalanches on Monday. A few small to large (size 1 to 2) avalanches were triggered over the weekend within the storm snow.

Snowpack Summary

Around 30 to 60 cm of snow since Saturday overlies a hard melt-freeze crust and perhaps isolated surface hoar crystals in wind-sheltered treeline terrain. The snow may be deeper and touchier in wind-exposed lee features.

A weak layer of surface hoar and/or faceted grains buried mid-February is around 50 to 100 cm deep.

The lower snowpack is well-settled.

Terrain and Travel Advice

  • Continue to make conservative terrain choices while the storm snow settles and stabilizes.
  • Be careful as you transition into wind-affected terrain.
  • Be aware of the potential for large avalanches due to buried weak layers.
  • Make observations and continually assess conditions as you travel.
  • Storm slabs in motion may step down to deeper layers resulting in large avalanches.
