Avalanche problems

  • Wind Slabs

    • Alpine
    • Treeline
    • Below treeline
    Likelihood
    Unlikely - Possible
    Size
    1–2
    New snow combined with a change in the wind loading pattern may have created new wind slabs in unexpected places

  • Cornices

    • Alpine
    • Treeline
    • Below treeline
    Likelihood
    Possible
    Size
    2–3
    Solar radiation is a common cornice trigger. Limit your exposure when it's cloudy and completely avoid cornices when it's sunny.

Confidence

Low - Due to the number of field observations

Avalanche Summary

There have been no recent reports of avalanche activity. That being said there is little to no information being reported from the region recently.

Snowpack Summary

Approximately 5-10cm of new snow has fallen earlier in the week. Variable light to moderate wind switching from south to east has redistributed this new snow at upper elevations. This new snow is likely sitting on a hard wind crust created by strong winds last week. Elevations below roughly 1300m are experiencing a daily melt-freeze cycle and the snowpack is likely moist or wet throughout its entire thickness. A persistent weak layer buried late February may be found down approximately 70-100cm and a deep persistent weak layer is still lingering near the bottom of the snowpack in all areas.
