Kernpunkte

Despite the lack of recent natural activity forecasters have low confidence in the snowpack. Conservative terrain choices are still advised. BW

    Feb 10 shears tightening up in deep snow pack areas west of the divide. In shallower snowpack areas this interface still producing whoomphing and easy to moderate shears.

Avalanche Summary

No avalanches were observed or reported today. A large sz.3 cornice triggered avalanche was reported on Tuesday in the Sunshine back country. This failed on the Feb.10 interface and stepped to ground in thin areas. We have seen sporadic natural activity like this over the last week.

Weather Forecast

Isolated flurries expected for Friday and mixed sun and cloud for Saturday. Light winds and a cooling trend forecast through to Saturday. Freezing levels at valley bottom.

Snowpack Summary

30-50 cm of storm snow throughout the region since March 15th which is starting to settle and bond to previous surfaces. There is some wind slabs in specific lee terrain in the alpine. The Feb.10th facet layer is down 80-120cm and is still showing easy to moderate test results in thinner snowpack areas, and harder results in deeper snowpack areas.
