Backcountry Advisory

comment

As of Wednesday, Dec 10

A vigorous weather system through Dec. 5th and 6th brought us 52cm of snow with moderate temperatures and strong winds. This system filled in the alpine nicely and made for great treeline storm skiing. Many of the steeper alpine slopes ran naturally through this 48-hour period.

When this system broke on the 7th, explosive testing and ski cutting resulted in mostly small size 1 surface slabs or no results at all. However, there was at least one size 2 avalanche in steep, rocky unsupported terrain initiated by helibombing on a NE aspect at the 2,100 metre elevation.

Snow profiles right after the storm had varying shears in the upper snowpack that have tightened over the past couple of days.

The weather through Tuesday, Dec. 9th has remained cool and clear which has led to the formation of surface hoar sized from 1mm to 7mm on all aspects and elevations. This is a feature to remember when we next receive snow. Stronger north winds on Tuesday have knocked a lot of these crystals down in the alpine.

The Avalanche Danger rating is currently listed as MODERATE. Conditions may vary and can change rapidly. Check out www.avalanche.ca for the most recent public avalanche bulletins throughout B.C.
