Highlights

Continually assess conditions throughout the day.

Conditions will vary from aspect to aspect and from morning to afternoon.

Avalanche problems

  • Wind Slabs

    • Alpine
    • Treeline
    • Below treeline
    Likelihood
    Possible
    Size
    1–2

    Wind slabs will likely remain rider triggerable on north and east aspects. Recent strong wind means that wind slabs may be found farther down slope than expected.

  • Loose Wet

    • Alpine
    • Treeline
    • Below treeline
    Likelihood
    Possible - Likely
    Size
    1–1.5

    Wet loose avalanches are possible on steep sun exposed slopes when the snow surface is wet or moist.

Confidence

Moderate

  • We are uncertain due to the variability of wind effect on the snowpack.

Avalanche Summary

Over the past couple days natural, rider and explosive triggered avalanches were reported to size 2. Activity primarily occurred in lee, wind affected terrain features at treeline and above.

Snowpack Summary

30 to 50 cm of recent snow sits over a crust/facet layer formed earlier this month. Deeper deposits will be found on north and east aspects and the crust may be on the surface on exposed ridges due to strong southerly wind. The snow surface is expected to become moist on sun exposed slopes during the day.

A widespread crust and facet layer from late January is buried 40 to 80 cm deep.

The mid and lower snowpack is well settled and strong.

Terrain and Travel Advice

  • Watch for newly formed and reactive wind slabs as you transition into wind-affected terrain.
  • Be aware of the potential for loose avalanches in steep terrain where snow hasn't formed a slab.
  • Be alert to conditions that change with elevation, aspect, and exposure to wind.
  • Pay attention to cornices and give them a wide berth when traveling on or below ridges.
