Kernpunkte

Surface conditions and recent precipitation amounts are variable. Verify conditions as you travel.

Back off steep slopes if you find moist surface snow and no supportive crust.

    Größe
    2.5–3.5

    Several persistent weak layers exist in the upper meter of the snowpack. Where these layers remain intact and there is no thick melt-freeze crust human-triggering remains possible.

  • Loose Wet

    Pulses of new snow and fluctuating freezing levels will see wet loose activity continue. Back off steep slopes where moist surfaces are found.

Avalanche Summary

On Saturday and Sunday, numerous small wet loose avalanches were reported across the region. Similar activity is expected to continue with pulses of new snow, fluctuating freezing levels, and periods of sun.

Snowpack Summary

New snow has buried a melt-freeze crust of variable thickness that increases in supportiveness as you gain elevation. Below this crust, snow remains moist in the upper snowpack.

Weak layers in the middle and lower snowpack remain a concern for human-triggering, where a hard melt-freeze crust has not yet formed or breaks down during periods of sun or rising freezing levels.

Terrain and Travel Advice

  • Back off slopes as the surface becomes moist or wet with rising temperatures.
  • A moist or wet snow surface, pinwheeling, and natural avalanches are all indicators of a weakening snowpack.
