Moderate

Avalanche Summary

Since last weekend, reports have been limited to small wind slabs and wet loose avalanches, along with a few cornices triggered by explosives.

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.

The snowpack thins quickly at lower elevations

Terrain and Travel Advice

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

Avalanche Problems

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

Loose Wet

Periods of sun could trigger wet loose avalanches.

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

Elevations: Alpine, Treeline.

Likelihood: Possible

Expected Size: 1 - 1.5
