In sintesi

Very touchy conditions will continue until the storm snow has a chance to settle.  Your best bet is to ski at the hill until the avalanche hazard drops.

Weather Forecast

The storm has past but flurries can be expected through sunday with further accumulations of 5 to 10 cms.  Mild temps will continue.  Light to moderate SW winds.

Snowpack Summary

Huge variation in the snowpack across the forecast region!! The Icefields Area received a whopping 40 to 60 cm overnight while areas to the north received much less.  Sensitive storm slab can be found on all aspects at treeline and above.  Rain and freezing rain fell below treeline in most areas. 

Avalanche Summary

A natural avalanche cycle with slides up to 3.5.  Avalanche control efforts along the Icefields Parkway produced large avalanches one bring down mature timber and burying the road.  Several avalanches initiated with just the weight of the bomb on the slope.

Confidence

Timing, track, or intensity of incoming weather system is uncertain on Sunday
