South Coast Inland, Birkenhead, Duffey, South Chilcotin, Stein, Taseko.

Assess terrain carefully and practice good group management

The best riding may be on the same features where triggering an avalanche is most likely

Avalanche Summary

No slab avalanches were reported in the past 4 days.

Snowpack Summary

A new crust likely exists on the surface except on high north facing terrain, where around 5 cm of snow overlies a crust from earlier in March. This second crust likely doesn’t exist above 2100 m.

A layer of facets and surface hoar from mid February can be found down around 40 cm.

Another layer of facets and surface hoar from late January can be found down 60 to 80 cm.

The lower snowpack contain several crusts that are not concerning.

Weather Summary

Thursday Night

Increasing cloud. 15 to 25 km/h west ridgetop wind. Treeline temperature -6 °C.

Friday

Mostly cloudy. 20 to 40 km/h southwest ridgetop wind. Treeline temperature -2 °C.

Saturday

Cloudy with 5 to 15 cm of snow. 50 to 70 km/h south ridgetop wind. Treeline temperature -2 °C.

Sunday

Cloudy with 10 to 30 cm of snow. 20 to 50 km/h south ridgetop wind. Treeline temperature -2 °C.

More details can be found in the Mountain Weather Forecast.

Terrain and Travel Advice

  • Avoid thin areas like rocky outcrops where you're most likely to trigger avalanches on deep weak layers.
  • Be careful as you transition into wind-affected terrain.

Problems

Persistent Slabs

Persistent Slab avalanches are the release of a cohesive layer of snow (a slab) in the middle to upper snowpack, when the bond to an underlying persistent weak layer breaks. Persistent layers include: surface hoar, depth hoar, near-surface facets, or faceted snow. Persistent weak layers can continue to produce avalanches for days, weeks or even months, making them especially dangerous and tricky. As additional snow and wind events build a thicker slab on top of the persistent weak layer, this avalanche problem may develop into a Deep Persistent Slab.
