Avalanche Summary

On Friday, several small size 1 loose dry and storm slab avalanches were triggered by riders in the Lizard Range.

On Thursday, a small naturally triggered wind slab 5 to 15 cm deep was observed in a fan feature in the Lizard Range.

Snowpack Summary

Up to 20 cm of new storm snow is sitting on 30 to 70 cm of faceted old snow overlying a weak layer formed in late January. This weak layer is a crust on sun-exposed slopes and a layer of surface hoar on all other aspects. Exposed terrain in the alpine and treeline is variably wind-affected, creating a stiffer slab above the weak layer. In turn, the stiffer slab may be easier to trigger under the weight of a human. The mid and lower snowpack is generally well settled with no other layers of concern.

Weather Summary

Friday Night

Cloudy with isolated flurries. 10 km/h west ridgetop wind. Treeline temperature -12 °C.

Saturday

Mostly cloudy. 15 km/h west ridgetop wind. Treeline temperature -15 °C.

Sunday

Cloudy with flurries up to 5 cm. 5 km/h southeast ridgetop wind. Treeline temperature -12 °C.

Monday

A mix of sun and clouds. 15 to 20 km/h northeast ridgetop wind. Treeline temperature -15 °C.

Terrain and Travel Advice

  • Keep your guard up as storm slabs may remain sensitive to human triggering.
  • Storm slabs in motion may step down to deeper layers resulting in large avalanches.
  • Approach steep and open slopes at and below treeline cautiously, as buried surface hoar may exist.
  • Be careful as you transition into wind-affected terrain.

Avalanche Problems

Storm Slabs

15 to 20 cm of low density new snow combined with moderate northwesterly wind has built fresh storm slabs.

Aspects: All aspects.

Elevations: All elevations.

Likelihood: Likely

Expected Size: 1 - 2

Persistent Slabs

Human triggered avalanches are possible where a cohesive slab has formed above a persistent weak layer of surface hoar and/or crust buried 30 to 70 cm deep.

Aspects: All aspects.

Elevations: All elevations.

Likelihood: Possible

Expected Size: 1.5 - 2.5
