Kernpunkte

UPDATED AT 6:50 AM: Strong winds and new snow are forming reactive wind slabs.

Areas sheltered from the wind will have better riding and lower avalanche hazard.

Lawinenprobleme

  • Wind Slabs

    • Hochgebirge
    • Waldgrenze
    • Unterhalb der Waldgrenze
    Wahrscheinlichkeit
    Very Likely
    Größe
    1–2

    Recent wind has varied in direction and strength. Wind slab could be present on all aspects and elevations.

  • Persistent Slabs

    • Hochgebirge
    • Waldgrenze
    • Unterhalb der Waldgrenze
    Wahrscheinlichkeit
    Unlikely - Possible
    Größe
    2–2.5

    Several surface hoar layers are buried 70 to 110 cm deep across the region. Their spatial distribution and reactivity are uncertain, so use extra caution on large, steep slopes.

Terrain and Travel Advice

  • Watch for newly formed and reactive wind slabs as you transition into wind-affected terrain.
  • Recent wind has varied in direction, so watch for wind slabs on all aspects.
  • Surface hoar distribution is highly variable. Avoid generalizing your observations.

Avalanche Summary

On Wednesday, a size 2 wind slab avalanche was observed at the Onion riding area. Otherwise, no other recent avalanches have been reported.

If you do observe an avalanche, please post a MIN report.

Snowpack Summary

15-20 cm of new snow overlies previous wind effect at treeline and alpine elevations. Areas sheltered from the wind are still holding soft snow.

A layer of surface hoar has been observed at depths of 70 to 110 cm throughout the northwest inland region. While no recent avalanches have involved this layer, some snowpack test results have been concerning.
