Regions: Kananaskis.

Winds picked up into the strong range today at higher elevations.  Sheletered areas at treeline are the most likely areas to find good skiing.  Best of luck to finding an untracked area though.

Confidence

Good

Weather Forecast

Light snowfalls expected throughout the day with temperatures cooling slightly and winds remaining strong out of SW.

Avalanche Summary

No new Natural avalanche activity. 

Snowpack Summary

Surface hoar growth on all aspects up to 2300m.  This surface hoar is up to sz 10mm in some areas and WILL be a problem persistent layer when its buried.  The Dec 13th interface is down 30-40cm and continues to produce moderate sheers on a layer of facets over this crust.  This crust, the Dec 13, is only being found up to 2250m-ish.  Below this the mid pack is generally well settled with the 1106cr down 1m.  Most alpine terrain is wind hammerred.

Avalanche Problems

Persistent Slabs

Heads in treeline areas.
Avoid cross loaded features.>Avoid unsupported slopes.>

Aspects: All aspects.

Elevations: Alpine.

Likelihood: Possible

Expected Size: 1 - 3

Deep Persistent Slabs

Thin weak areas are the places wherein you may be able to trigger this weakness.
Avoid convexities or areas with a thin or variable snowpack.>

Aspects: All aspects.

Elevations: Alpine, Treeline.

Likelihood: Unlikely - Possible

Expected Size: 3 - 5
