Highlights

Forecasters remain uncertain that the Feb 27 storm load has fully settled and stabilized. There is a decrease in natural activity yet it continues in our nearest neighbors. There remains potential to produce large deadly avalanches. Consider the size of slopes and overhead hazard in your decision-making process.

Avalanche problems

  • Wind Slabs

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

    Strong alpine winds during and after the Feb 27 storm extensively redistributed snow into Windslabs on a variety of slopes and aspects. There remains the potential to encounter this condition lower on slopes.

  • Persistent Slabs

    • Alpine
    • Treeline
    • Below treeline
    Likelihood
    Possible - Likely
    Size
    1.5–3.5

    Feb 27 storm snow and accompanying strong winds built a cohesive slab. A natural cycle, up to size 3.5, has been observed on this layer on the days following the storm plus a skier triggered size 2 near miss occurred on Saturday at Hilda ridge. Stability is improving.

Confidence

Moderate

  • We are confident that there are persistent slabs in the snowpack, but uncertain about how likely they are to trigger.

Avalanche Summary

March 3rd Maligne's explosive control released a couple size 1 persistent slabs. Visibility was poor to note any new naturals. March 2nd saw a significant avalanche on the East face of Whistlers Peak. Our neighbors to the West and South are still reporting natural activity. Natural avalanches up to size 3.5 were observed Feb 27-Mar 1st. A skier triggered size 2 near miss occurred on Feb 28 at Hilda ridge. See the MIN.

Snowpack Summary

Feb 26-27th brought upwards of 40 cm of new snow locally at the Icefields area. Since then, it has been redistributed by moderate to strong West winds. This sits atop the January weak layer of facets and surface hoar down 40–60 cm, forming a persistent slab. Below 2000m, a thin melt-freeze crust is developing on the surface with warm daytime temperatures. The mid-pack is well consolidated but basal facets are found in thinner areas.

Weather Summary

Weather conditions for Wednesday are expected to be flurries, 6 cm of new snow, -2 °C, light winds, and 1800 metres freezing level. Thursday and Friday could be clouds, sun, flurries, trace of new snow, light gusting moderate West winds, and -3 to -10 °C.

Terrain and Travel Advice

  • Look for signs of instability: whumphing, hollow sounds, shooting cracks, and recent avalanches.
  • Recent strong wind means wind slabs may be found farther downslope than expected.
