Expect loose dry sluffing of new snow in steep terrain and running fast where a crust is present.

Good skiing in the alpine rapidly deteriorate below 2000m with moist snow and rugged terrain.

    20-40 cm of light snow is triggerable in steep terrain. This problem is more reactive where a crust in present below the storm snow.

Avalanche Summary

Midday on Wednesday, a cycle of natural and skier triggered loose dry avalanches were observed in the Connaught valley.

A group bootpacking a couloir on the S side of Avalanche Mtn triggered a sz 2.5-3 avalanche yesterday. Use caution in this extreme terrain, where the snowpack might be variable and weak.

Spring-like temperatures and rain last week triggered a widespread avalanche cycle. Many avalanches gouged to ground in gully features and reached the valley floor.

Snowpack Summary

15-20cm of new snow sits over a robust crust that formed during recent warm weather. This crust has been observed up to 2500.

Warm temperatures have rounded and strengthened the mid and lower snowpack.

Be prepared for challenging travel over refrozen avalanche debris and shallow snowpack hazards at and below Tree-line. The snowpack is approximately 20cm below the previous record low.

Weather Summary

Expect flurries and cooling temps over the next 3 days, with a bit of a clearing trend on Friday.

Terrain and Travel Advice

  • Loose avalanches may start small but they can grow and push you into dangerous terrain.
  • Be cautious of buried obstacles especially below treeline.
