Start your day early and watch the crust closely.

As it breaks down, reduce your exposure to avalanche terrain.

Avalanche Summary

Wet loose avalanches have been occurring on steep slopes facing the sun. Mostly small, but some large avalanches (size 2 to 3).

Snowpack Summary

A thin surface crust is expected to cover up to 25 cm of recent snow at upper elevations. This snow overlies a robust crust everywhere except northerly aspects in the alpine.

Most terrain has undergone strong melt-freeze cycles, but the snowpack remains slightly more complex on north-facing alpine slopes, where buried weak layers may still be present.

Weather Summary

Thursday Night

Mostly clear skies. 20 to 30 km/h south ridgetop wind. Treeline temperature 1 °C. Freezing level 2500 m.

Friday

Sunny. 10 to 20 km/h south ridgetop wind. Treeline temperature 5 °C. Freezing level 2700 m.

Saturday

Mix of sun and cloud. 10 km/h variable direction ridgetop wind. Treeline temperature 7 °C. Freezing level 2700 m.

Sunday

Mix of sun and cloud. 10 km/h northwest ridgetop wind. Treeline temperature 5 °C. Freezing level 2500 m.

Terrain and Travel Advice

  • Pay attention to cornices and give them a wide berth when traveling on or below ridges.
  • Avoid steep, sun-exposed slopes when the air temperature is warm or when solar radiation is strong.
  • Avalanche danger will increase as the surface crust breaks down.

Avalanche Problems

Loose Wet

Wet loose avalanches will become more likely as the sun and warmth affect the snowpack. Start early, and avoid the hottest part of the day.

Aspects: East, South East, South, South West, West.

Elevations: All elevations.

Likelihood: Possible - Likely

Expected Size: 1 - 3

Cornices

Large cornices hang over many ridges and are more likely to collapse during warm, sunny weather.

Aspects: North, North East, East, South East, North West.

Elevations: Alpine.

Likelihood: Unlikely - Possible

Expected Size: 1.5 - 2.5
