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

By mid day on Thursday up to 10 cm of new snow could have accumulated with moderate southwest wind. This new snow will overlie a crust on all aspects and elevations, except for north facing terrain above 2000 m, Where up to 20 cm overlies a 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.

The remainder of the snowpack is generally well settled.

Weather Summary

Wednesday Night

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

Thursday

Mix of sun and cloud with 0 to 3 cm of snow. 15 to 30 km/h northwest ridgetop wind. Freezing level rising to 1800 m.

Friday

Sunny. 10 to 20 km/h northwest ridgetop wind . Freezing level rising to 2000 m.

Saturday

Sunny. 10 to 25 km/h southwest ridgetop wind. Freezing level rising to 2300 m.

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.
  • 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
