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.

Problems

Storm Slabs

An icon showing 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
