Avalanche Summary

Recent reports have been limited to small wet loose avalanches on sun-exposed slopes.

Snowpack Summary

Unsettled weather has delivered about 10 cm of snow which may have formed some isolated wind slabs at higher elevations. This snow overlies a widespread melt-freeze crust, with the exception of high elevation northerly aspects where the snow sits above a small surface hoar layer.

Deeper in the snowpack, a persistent weak layer from late January is buried around 80 to 150 cm and is composed of a combination of surface hoar, facets, and crusts. We haven't received a report of avalanche activity on this layer since late February and the likelihood of triggering this layer is currently low.

As always, best to avoid shallow, rocky areas where a weak and faceted snowpack may be found.

Terrain and Travel

  • Watch for wind-loaded pockets especially around ridgecrest and in extreme terrain.
  • Pay attention to cornices and give them a wide berth when traveling on or below ridges.
