Points saillants

Travel cautiously on steep slopes where the snow surface is wet. Give cornices a wide berth, as they could release unexpectedly.

    Wet avalanches remain possible on steep terrain anywhere the snow surface is wet. As the freezing level slowly decreases, so will the likelihood of avalanche activity.

Confidence

Moderate

  • We are uncertain due to a limited number of field observations.

Avalanche Summary

Many small wet loose and slab avalanches were observed during warm weather over the past few days. They've been observed on all aspects and elevations.

Looking forward, avalanche activity is expected to slowly decrease as cooler and cloudier weather arrives. Until that happens, continue to travel conservatively anywhere the snow surface is wet and slushy and near cornices.

Snowpack Summary

Wet snow exists to mountain top, which will slowly freeze into a melt-freeze crust at higher elevations as cooler weather arrives. The snow surface will remain wet on sun-exposed slopes and at lower elevations.

Various hard crusts are found in the top half of the snowpack. In the high alpine near Invermere, a layer of weak facets may persist above one of these crusts, found 30 to 80 cm deep.

The snowpack continues to melt below treeline.

Terrain and Travel Advice

  • Be alert to conditions that change with elevation, aspect, and exposure to wind.
  • 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.
