Kernpunkte

Snowfall amounts are uncertain.

If you see over 20 cm of new snow, dangerous storms slabs are likely.

Lawinenprobleme

  • Cornices

    • Hochgebirge
    • Waldgrenze
    • Unterhalb der Waldgrenze
    Wahrscheinlichkeit
    Unlikely
    Größe
    1.5–2.5

    Cornices may break further back on ridgelines than expected, falling on the slope below and possibly triggering a slab.

  • Storm Slabs

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

    Wet, heavy snow at higher elevations may slide easily on the old snow surfaces. Watch for deeper pockets in areas lee to the wind, they're likely easier to trigger too.

  • Loose Wet

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

    Continued rain at lower elevations is causing the snowpack to lose cohesion and possibly fail as wet loose avalanches.

Avalanche Summary

Over the weekend, small wet loose avalanches were reported to size 1.

Riders may be able to trigger slabs in areas with more than 20 cm of new snow, especially deeper areas lee to the wind. While at lower elevations, rain soaked snow may lose cohesion and fail as wet loose avalanches.

Confidence

Moderate

Snowpack Summary

Up to 20 cm of snow fell at higher elevations on Tuesday, with more on the way. This snow is on either a crust up high, or moist snow down low. At lower elevations, the new snow may have fallen as rain and made the upper pack wet and loose. There are currently no deeper layers of concern.

Terrain and Travel Advice

  • Continue to make conservative terrain choices while the storm snow settles and stabilizes.
  • A moist or wet snow surface, pinwheeling, and natural avalanches are all indicators of a weakening snowpack.
  • Cornices often break further back than expected; give them a wide berth when traveling on ridgetops.
