Avalanche Summary

A widespread avalanche cycle up to size 3 was reported on Wednesday, avalanche activity has since tapered.

Snowpack Summary

At upper elevations, upwards 0f 20 cm wet flurries accumulated through Friday. Below 1100 m, the upper snowpack is wet and unconsolidated from above-freezing temperatures and rain.

A robust crust, formed in early March, can be found in the mid-pack. The snow above is well bonded to this crust. Below this, the snowpack is well consolidated and strong.

Terrain and Travel Advice

  • Avoid freshly wind-loaded terrain features.
  • Be alert to conditions that change with elevation, aspect, and exposure to wind.
  • Avalanche activity is unlikely when a thick melt-freeze crust is present on the snow surface.
  • Approach lee and cross-loaded slopes with caution.
