    Large cornices or surface avalanches are the likely trigger for this deep persistent weak layer.

Weather Forecast

A small system is expected to bring 6 - 10cm of new snow for Saturday.  This will combine with sun and clouds to make some good skiing weather.

Snowpack Summary

Soft slabs were observed on Northerly aspects around terrain features in the Whistler creek area at alpine and treeline elevations. A temperature crust can be found on all aspects up to 2500m. A supportive midpack sits over a weak basal facet layer in most areas at treeline and above. Large cornices exist at ridge line.

Avalanche Summary

No new natural avalanches reported in the forecast area. No natural avalanches were observed during a fieldtrip to the Whislter creek drainage. However, some snowballing was evident on solar aspects in the afternoon

Confidence

Intensity of incoming weather systems is uncertain on Saturday
