Rider triggered avalanches are possible.

Use caution in steep and unsupported terrain where fresh storm slabs have formed.

Summary

Confidence

Moderate

Avalanche Summary

Riders reported triggering small wind slabs, up to size 1.5, in steep north facing terrain off Cheops Mtn. in Connaught creek on Thursday.

Also on Thursday, isolated natural slab avalanches sized, 2, 2.5 and 3 were observed in from steep, alpine start zones on N and SE aspects.

On Tuesday, a skier triggered a very small wind slab near the Forever Young Couloir.

Expect loose sluffing on dry snow in steep and unsupported terrain.

Snowpack Summary

Spring convective flurries have added 10-30 cm of storm snow, which has been redistributed by wind in the alpine. Surface snow turns moist below 1700 m.

Below the storm snow is a thick crust on all aspects below 1700m and widespread on solar facing terrain.

A weak layer formed on March 9th is down ~30 cm and the Feb 3rd persistent weak layer is down 80-140 cm deep, both these layers are currently unreactive. The mid and lower snowpack are well settled and strong.

Weather Summary

A frontal system exiting the region will bring light convective flurries Friday. A ridge of high pressure builds on Saturday.

Tonight: Flurries. Snow: 5 cm, alpine temp: Low -6 °C, SW winds 10km/hr, FZL valley bottom

Fri: Flurries, Snow: 5cm, alpine high -5 °C, NW winds 10km/hr, FZL 1500m

Sat: Sun/Cloud. Alp high -5 °C, W winds 10-25km/hr, FZL 1500m

Sun: Sun/Cloud. Alp high -3 °C, light winds, FZL 1900m

Terrain and Travel Advice

  • Look for signs of instability: whumphing, hollow sounds, shooting cracks, and recent avalanches.
  • Remember that the snowpack will be significantly different at higher elevations than lower down.
  • The best and safest riding will be on slopes that have soft snow without any slab properties.

Problems

Storm Slabs

An icon showing Storm Slabs

Convective storm flurries will add up to 40 cm in some terrain. Warm temperatures and wind effect have formed storm slabs. Use caution in steep, convex terrain and places where a strong crust sits under the storm snow.

Aspects: All aspects.

Elevations: Alpine, Treeline.
