Kernpunkte

Continuously verify conditions as you move through terrain.

Avalanche hazard will vary from aspect to aspect and at different elevations.

Lawinenprobleme

  • Wind Slabs

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

    New snow and strong winds have formed wind slab at higher elevations. Strong wind means that wind slabs could be found further down slope than expected.

  • Persistent Slabs

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

    Large avalanches could be triggered from thin spots or with a large load, like a cornice fall.

  • Loose Wet

    • Hochgebirge
    • Waldgrenze
    • Unterhalb der Waldgrenze
    Wahrscheinlichkeit
    Likely
    Größe
    1–1.5

    Wet loose avalanches are likely when the snow surface feels wet or slushy.

Confidence

Moderate

  • We are uncertain due to rapidly changing freezing levels.

Avalanche Summary

At the time of publishing we had not received reports of new avalanches but we expect that natural avalanche activity may have occurred in the region on Monday.

Over the weekend, explosive control has produced small wind slabs.

Snowpack Summary

15 to 30 cm of new snow overlies a crust at lower elevations. At treeline and above this new snow has been redistributed by strong southwest wind, forming deep deposits on north and east facing terrain.

Within the top 100 cm of the snowpack, there are a few layers of surface hoar, facets, crusts, or a combination of the three.

The remainder of the snowpack is well settled and strong.

Weather Summary

Monday Night
Cloudy. 60 km/h southwest ridgetop wind. Treeline temperature 0 °C. Freezing level 1900 m.

Tuesday
Cloudy. 50 km/h southwest ridgetop wind. Treeline temperature 2 °C. Freezing level 2100 m.

Wednesday
Mostly cloudy. 1 to 3 mm of rain at treeline. 50 km/h southwest ridgetop wind. Treeline temperature 4 °C. Freezing level 2400 m.

Thursday
Mix of sun and clouds. 2 mm of rain at treeline. 50 km/h southwest ridgetop wind. Treeline temperature 3 °C. Freezing level 2300 m.

Terrain and Travel Advice

  • Watch for newly formed and reactive wind slabs as you transition into wind-affected terrain.
  • Recent strong wind means wind slabs may be found farther downslope than expected.
  • Back off slopes as the surface becomes moist or wet with rising temperatures.
  • Avoid shallow, rocky areas where the snowpack transitions from thick to thin.
