Regions: Kananaskis.

At the risk of sounding like a broken record we need some new snow!  Widespread slab conditions and seriously eroded snowpack in all open terrain. Most popular areas heavily tracked up.  The few cm's of new snow we may see tomorrow not enough yet.

Confidence

Good

Weather Forecast

Arctic ridge staying to the east of the forecast area  so we can still look forward to mild temps.  A few cm of new snow in the forecast for Wednesday but not enough to promote healing of an ailing snowpack.  Wind values will decrease slightly although for the most part they were light on Tuesday PM  anyways!

Avalanche Summary

No new natural avalanches observed or reported.

Snowpack Summary

No change - widespread hard and soft slab conditions with serious wind degradation in all open terrain.  Midpack continues to weaken under the influence of facetting.

Avalanche Problems

Wind Slabs

30-40cm thick windslabs are being encountered on north to southeast aspects at treeline and above. Expect wide propagations due to the hard nature of these slabs.
Avoid exposure to terrain traps where the consequences of a small avalanche could be serious.>Be aware of the potential for full depth avalanches due to deeply buried weak layers.>Be careful with wind loaded pockets while approaching and climbing ice routes.>

Aspects: North, North East, East, South East, South.

Elevations: Alpine, Treeline.

Likelihood: Possible

Expected Size: 2 - 4
