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.
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.
