Points saillants

Sheltered, shaded terrain holds the best riding, but large cornices above may be a concern.

Space out to avoid exposing multiple people to a slope at once, and give cornices a wide berth.

Confidence

High

  • We have a good understanding of the snowpack structure and confidence in the weather forecast.

Avalanche Summary

On Monday, north of Pemberton, small loose dry, rider triggered avalanches and sluffs were reported in steep terrain.

If you are heading into the backcountry, consider sharing your observations and posting a MIN.

Snowpack Summary

New snow could give a light refresh to the upper snowpack in sheltered areas.

Expect to find 30 to 50 cm of settling snow over a thick and hard crust below about 1900 m, and old wind-affected snow at upper elevations.

Steep slopes that usually face the sun may have a thin breakable crust on or near the surface.

Two older crusts (1-1.5 m deep), buried in early February and March previously produced large to very large avalanches, but they seem to have gained strength and are not a current concern.

Terrain and Travel Advice

  • Pay attention to cornices and give them a wide berth when traveling on or below ridges.
  • Be alert to conditions that change with elevation, aspect, and exposure to wind.
  • Avoid terrain traps such as gullies and cliffs where the consequence of any avalanche could be serious.
