Bollettino valanghe Kananaskis — Jan 27, 2020

In sintesi

Good skiing with settled snow can be found in sheltered areas of tree line and below. The alpine has widespread wind slabs.

There are several generations of wind slabs that need some more time to heal.

It is worth to dig a pit to ground to see the severity of this basal layer.

Weather Forecast

Tuesday is expected to be a mix of cloud and sun with a chance of flurries. In the alpine, temps will be between -6c and -9c with light to moderate SW winds. Wednesday looks like a carbon copy of Tuesday.

Avalanche Summary

No new avalanches were observed.

Snowpack Summary

The alpine has widespread wind slabs that carry into the tree line (specific to ridges). The top 50cm of the snowpack is made up mostly of buried wind slabs that are still producing sheers. These will settle out with time but presently, still a concern for triggering them in the alpine and along ridges and lee features. This can cause the basal weakness to wake up and produce large avalanches. The weak temperature gradient within the snowpack is having a positive effect on the snowpack over the long haul. The basal facets/crust combo 40cm off the ground will be on our radar for a long time

Terrain and Travel

If triggered, wind slabs avalanches may step down to deeper layers resulting in larger avalanches.
Carefully evaluate steep lines for wind slabs.
Avoid lee and cross-loaded slopes at and above treeline.
