Kernpunkte

Uncertainty remains on how quickly the snowpack will recover and gain strength.

Conditions will vary with elevation, from wet snow to surface crust.

Make observations as you travel.

Lawinenprobleme

  • Loose Wet

    • Hochgebirge
    • Waldgrenze
    • Unterhalb der Waldgrenze
    Wahrscheinlichkeit
    Possible
    Größe
    1–2

    Triggering remains possible in areas where the surface snow is still wet. Large avalanches are possible at lower elevations, where the snowpack is wet to the ground.

  • Wet Slabs

    • Hochgebirge
    • Waldgrenze
    • Unterhalb der Waldgrenze
    Wahrscheinlichkeit
    Possible - Likely
    Größe
    1.5–2.5

    The upper snowpack is soaked and overlies a supportive crust. Use caution at elevations without a supportive surface crust, where triggering may still be possible.

Confidence

Moderate

  • We are uncertain due to a limited number of field observations.
  • We are uncertain about how quickly the snowpack will recover and gain strength.
  • We are uncertain due to variable freezing levels.

Avalanche Summary

On Thursday, numerous wet loose and wet slab avalanches (up to size 2.5) were observed in the surrounding terrain of Castle Mountain.

In the neighboring Fernie region, very large avalanche debris (up to size 3) were reported, indicating a widespread natural cycle occuring Wednesday to Thursday.

If you are heading into the backcountry, please consider sharing conditions via the MIN.

Snowpack Summary

High freezing levels and heavy rain have saturated the top 20 to 50 cm of surface snow up to the mountain tops.

As freezing levels drop, a widespread crust will start to form on all aspects and higher elevations.

Below this, 30 to 50 cm of wet snow sits above a crust.

The mid and lower snowpack are generally well consolidated with early-season crusts deep in the snowpack.

The snowpack rapidly diminishes at lower elevations and is moist to the ground in shallower areas.

Terrain and Travel Advice

  • A moist or wet snow surface, pinwheeling, and natural avalanches are all indicators of a weakening snowpack.
  • Keep in mind that the high density of wet avalanches can make them destructive.
  • Avalanche activity is unlikely when a thick melt-freeze crust is present on the snow surface.
