    Where a melt-freeze crust has developed, this layer will be difficult to trigger. Areas of concern are steep, rocky terrain, where a melt-freeze crust might not exist.

Confidence

Low

Avalanche Summary

Small, natural and skier triggered wet and dry loose avalanches continue to be reported in the region.

Snowpack Summary

The upper  snowpack is highly variable. A crust exists on or near the surface on all aspects below treeline and on all sun exposed slopes.  On north aspects, Up to 20 cm of snow has buried a melt-freeze crust from late March. Below these crusts, the upper snowpack is moist.

A weak layer of facets from late January can be found down around 1 meter.

Weather Summary

Precipitation amounts over the next 24hrs could be highly variable due to convection.

Terrain and Travel Advice

  • Avalanche activity is unlikely when a thick melt-freeze crust is present on the snow surface.
  • Make observations and continually assess conditions as you travel.
  • Back off slopes as the surface becomes moist or wet with rising temperatures.
