Regions

Kananaskis.

Not much is changing out there right now.  The strong SW winds have destroyed the skiing in Alpine areas and pretty much all treeline areas are tracked up.  We will need about 30cm of new snow to re-set the forecast region. Low ski pen though!

Confidence

Good

Weather Forecast

Well....  Not to sound like a broken record but...  If i was to cut and paste yesterdays forecast that would be accurate!  Winds are forecast to continue and no new snow is forecast for the next few days.  Some people were even rock climbing today in the eastern part of the forecast region!

Avalanche Summary

No new natural avalanche activity was observed.

Snowpack Summary

Little Change.  Widespread hardslabs in all open wind affected terrain.  LOTS of bard rock showing from the winds that have ravaged the area over the past few days.

Problems

Wind Slabs

Wind Slab avalanches are the release of a cohesive layer of snow (a slab) formed by the wind. Wind typically transports snow from the upwind sides of terrain features and deposits snow on the downwind side. Wind slabs are often smooth and rounded and sometimes sound hollow, and can range from soft to hard. Wind slabs that form over a persistent weak layer (surface hoar, depth hoar, or near-surface facets) may be termed Persistent Slabs or may develop into Persistent Slabs.
