Moderate

Avalanche Summary

Observations since the weekend have been limited to small, explosive-triggered cornices (size 1 to 2) and wet loose avalanches.

Following last week's widespread avalanche cycle, the persistent slab problem is now dormant and would likely require a very large cornice fall on an isolated slope to trigger.

Snowpack Summary

Dry, settled powder may still be found on high north-facing slopes, while elsewhere, a daily melt-freeze cycle is creating a hard crust overnight that softens during the day.

Old persistent weak layers may still exist 1 to 3 m deep on high north-facing slopes, but they are rounding and unreactive under current conditions.

At lower elevations, the rain-saturated snowpack thins rapidly with elevation.

Weather Summary

Thursday Night

Clear. Calm. Treeline temperature -1 °C. Freezing level 1700 m.

Friday

Mostly sunny. 10 km/h southeast ridgetop wind. Treeline temperature 0 °C. Freezing level 1900 m.

Saturday

Mix of sun and cloud. 30 km/h south ridgetop wind. Treeline temperature +3 °C. Freezing level 2300 m.

Sunday

Cloudy with 5 to 10 cm of snow above 1800 m, rain below. 50 km/h southeast ridgetop wind. Treeline temperature 0 °C. Freezing level 2000 m.

Terrain and Travel Advice

  • Carefully evaluate big and steep terrain features before committing to them.
  • Limit exposure to steep, sun exposed slopes, especially when the solar radiation is strong.
  • Pay attention to cornices and give them a wide berth when traveling on or below ridges.

Avalanche Problems

Loose Wet

Periods of sun will likely trigger wet loose avalanches.

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

Elevations: Alpine, Treeline.

Likelihood: Possible - Likely

Expected Size: 1 - 1.5

Cornices

Cornices hang over ridges and may be triggered by sunshine or people travelling along ridgelines.

Aspects: North, North East, North West.

Elevations: Alpine.

Likelihood: Unlikely - Possible

Expected Size: 2 - 2.5
