Avalanche Summary

Small wet and dry loose avalanches continue to be triggered by skiers in steep terrain. Some small slab avalanches have also been reported on high north facing terrain where dry snow still remains.

Snowpack Summary

The upper  snowpack is variable. A crust exists on or near the surface on all aspects below treeline and on all sun exposed slopes.  On north aspects, Up to 30 cm of snow has buried a thick melt-freeze crust from late March. Below these crusts, the upper snowpack is moist.

Several weak layers from early March, mid February and late January can be found in the mid and lower snowpack.

Weather Summary

Precipitation amounts over the next 24hrs could be highly variable due to convection.

Tuesday Night

Mostly cloudy with 0 to 5 cm of snow. 15 to 30 km/h west ridgetop wind. Treeline temperature -3 °C.

Wednesday

Cloudy with 0 to 5 cm of snow. 20 to 30 km/h southwest ridgetop wind. Treeline temperature -1 °C.

Thursday

Mix of sun and cloud with around 5 cm of snow. 15 to 30 km/h west ridgetop wind. Treeline temperature -3 °C.

Friday

Sunny. 10 to 20 km/h northwest ridgetop wind . Treeline temperature -1 °C.

More details can be found in the Mountain Weather Forecast.

Terrain and Travel Advice

  • Back off slopes as the surface becomes moist or wet with rising temperatures.
  • A moist or wet snow surface, pinwheeling, and natural avalanches are all indicators of a weakening snowpack.
  • Avalanche activity is unlikely when a thick melt-freeze crust is present on the snow surface.
  • Make observations and continually assess conditions as you travel.

Avalanche Problems

Loose Wet

Pulses of new snow and fluctuating freezing levels will likely keep wet loose avalanches possible.

Dry loose avalanches are also possible where recent snow hasn't formed a slab or become moist .

Aspects: All aspects.

Elevations: Alpine, Treeline.

Likelihood: Possible

Expected Size: 1 - 1.5

Storm Slabs

Expected precipitation amounts are highly variable. If 15 cm of new snow accumulates new, small storm slabs could be possible.

Aspects: All aspects.

Elevations: Alpine, Treeline.

Likelihood: Possible

Expected Size: 1 - 1.5
