Weather Forecast

Sunday: light flurries in the evening. Moderate southwest winds and freezing levels rising to 2000m.

Monday: stormy weather with 10 mm of precipitation and moderate southwest winds. Freezing level around 1500 m.

Avalanche Summary

We suspect natural avalanches could occur on Friday. If you observe any avalanche activity in the backcountry please consider filling out a Mountain Information Network report.

Snowpack Summary

Wind slab will likely be found on north and east aspects.

Up to 60cm sits above a thick and supportive crust that extends to mountain top. In the far north and east of the forecast region a layer of facets and surface hoar could be found above this crust.

The middle and base of the snowpack are well settled and strong. In isolated areas north in the region, a layer of faceted grains on a crust may be found 150-200 cm deep; however, observations suggest that this layer has become unreactive. 

Terrain and Travel

  • Watch for newly formed and reactive wind slabs as you transition into wind affected terrain.
  • Continue to make conservative terrain choices while the storm snow settles and stabilizes.
  • Back off slopes as the surface becomes moist or wet with rising temperatures.

Avalanche Problems

Storm Slabs

New storm and wind slabs will form throughout the day on Friday. Sensitivity to triggering will be greatest on wind loaded features on north and east aspects. Strong winds mean that wind slab could be found further down slope than expected.

Aspects: All aspects.

Elevations: Alpine, Treeline.

Likelihood: Very Likely

Expected Size: 1 - 2

Loose Wet

Rising freezing levels on Saturday could result in a loose wet cycle at and below treeline. Small wet slabs could also be triggered.

Aspects: All aspects.

Elevations: Treeline, Below Treeline.

Likelihood: Very Likely

Expected Size: 1 - 2
