Wind slabs may linger near the mountain tops on atypical slopes.

Avalanche Summary

We didn't hear of any new avalanche observations on Sunday or Monday. Numerous small storm slabs released on Saturday during stormy weather.

Looking forward, human-triggered wind slab avalanches are possible in southerly slopes near mountain tops.

Snowpack Summary

On sun-exposed slopes and below 1000 m, a surface melt-freeze crust exists from Tuesday's sun and warm air. Above 1000 m on shaded slopes, anywhere from a dusting to 10 cm of dry snow rests above a melt-freeze crust that formed during the weekend's rain. Strong to extreme northerly wind redistributed this snow into wind slabs on atypical southerly slopes. These wind slabs may linger at high elevations.

The remainder of the snowpack is consolidated and strong.

Weather Summary

Tuesday Night

Increasing clouds with no precipitation, 20 km/h west wind, treeline temperature -3 °C.

Wednesday

Cloudy with light snowfall, accumulation 1 to 3 cm, 30 km/h southwest wind, treeline temperature -3 °C, freezing level 600 m.

Thursday

Cloudy with snowfall, accumulation 10 to 20 cm, 60 km/h southwest wind, treeline temperature -2 °C, freezing level 800 m.

Friday

Cloudy with snowfall then clearing, accumulation 5 cm, 20 km/h northwest wind, treeline temperature -2 °C, freezing level 800 m.

Terrain and Travel Advice

  • Carefully evaluate steep lines for wind slabs.
  • When a thick, melt-freeze surface crust is present, avalanche activity is unlikely.

Avalanche Problems

Wind Slabs

Wind slabs may linger on atypical southerly slopes at high elevations. Assess for them prior to committing to large terrain features.
