Highlights

Cornice and wet loose avalanches are possible in steep terrain.

Use caution on sun-exposed slopes and always practice good travel habits.

    1.5–2.5

    Cornices will become weak with sun and daytime warming. There's an isolated change a cornice failure could trigger a slab avalanche on the slope below.

    Periods of sun and warming may trigger avalanches on steep slopes.

Avalanche Summary

A few small loose wet avalanches have been observed recently and may continue during periods of warming and sun.

Observations have been very limited recently. If you are out in the mountains this weekend, consider submitting a MIN post.

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.

An old persistent weak layer may still be present 100 to 150 cm below the surface on high north-facing slopes, but it is rounding and unreactive under current conditions.

Treeline elevations still hold over 200 cm of snow, but coverage is rapidly thinning at lower elevations.

Terrain and Travel Advice

  • Make observations and continually assess conditions as you travel.
  • 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.
