Avalanche Forecast

Issued: Mar 8th, 2022 3:00PM

The alpine rating is moderate, the treeline rating is low, and the below treeline rating is low. Known problems include Wind Slabs and Persistent Slabs.

Avalanche Canada JMackenzie, Avalanche Canada

Lots of good skiing to be found, but continue to watch for pockets of wind slab at upper elevations. Buried sun crusts on solar aspects could be reactive in steeper terrain, especially during periods of intense solar radiation.

Summary

Confidence

High -

Weather Forecast

Wednesday will be mostly sunny and cold with temps ranging from -28 to -15. Winds will be generally light from the north.

Thursday is mainly cloudy and slightly warmer, with a slight chance of flurries in the afternoon.

Avalanche Summary

No new avalanches observed on Tuesday.

Snowpack Summary

Up to 15cm of new snow in the past 24 hours brings recent storm snow totals to between 40 and 60cm. The recent snow remains low density with isolated wind effect in wind prone areas of the Alpine. On solar aspects a series of buried sun crusts are interspersed with soft snow, which is tending to make the ski quality poor on solar aspects. Forecasters continue to monitor the Feb 19th interface (sun crust on solar aspects and hard slab everywhere else) now buried 40 to 60cm. This interface has produced a small amount of natural avalanches in past days, and may become more of a problem as the density of the recent storm snow increases (due to warming, wind and/or settlement). Take the time to dig down frequently and evaluate the bond at this interface.

Terrain and Travel

  • Be alert to conditions that change with elevation and wind exposure.
  • Wind slabs may be poorly bonded to the underlying crust.
  • Minimize exposure to sun-exposed slopes when the solar radiation is strong.

Problems

Wind Slabs

An icon showing Wind Slabs

Watch for wind slabs in the Alpine in lee and cross-loaded features.

Aspects: All aspects.

Elevations: Alpine.

Likelihood

Possible

Expected Size

1 - 2

Persistent Slabs

An icon showing Persistent Slabs

Carefully evaluate the bond of the recent snow to the underlying crust. Steep solar aspects and unsupported terrain should be carefully considered or avoided. Intense solar input will make this problem much more reactive.

Aspects: South East, South, South West, West.

Elevations: Alpine, Treeline.

Likelihood

Possible

Expected Size

1.5 - 2.5
