Regions

Kananaskis.

This is the time to go ice climbing as skiing is rather challenging/scary thin at the moment.  The drought word is slowly beginning to be used around the forecasters office here. 

Confidence

Good

Weather Forecast

Fridays weather looks to be much like a carbon copy of thursdays.  No new snow, mix of sun and cloud and generally calm winds.  The ddddddrought word is creeping into our vocabulary. 

Avalanche Summary

No new avalanches observed.

Snowpack Summary

Very little change over the past few days.  Steep solar aspects have a sun crust and there is widespread surface hoar growth up to 15mm below 2300m.  Cold temps facetting out the snowpack at lower elevations. 

Problems

Persistent Slabs

Persistent Slab avalanches are the release of a cohesive layer of snow (a slab) in the middle to upper snowpack, when the bond to an underlying persistent weak layer breaks. Persistent layers include: surface hoar, depth hoar, near-surface facets, or faceted snow. Persistent weak layers can continue to produce avalanches for days, weeks or even months, making them especially dangerous and tricky. As additional snow and wind events build a thicker slab on top of the persistent weak layer, this avalanche problem may develop into a Deep Persistent Slab.
