    Wind slabs between 20 and 40cm thick are found in lee and cross-loaded features in the Alpine and open areas at Treeline. Terrain immediately below ridge-crests seems especially prone to this problem.

      The Feb10th layer down 80 to 120cm remains a concern. Sporadic avalanche activity on this layer continues to occur on all aspects.

Confidence

Fair - Timing, track, or intensity of incoming weather system is uncertain

Weather Forecast

Tuesday should be cloudy with light flurries and accumulations up to 5cm. Winds will be out of the West gusting to 45km/h. Forecasts are in disagreement, but Tuesday night and Wednesday morning could see heavy snow with as much as 30cm possible.

Avalanche Summary

Several small sluffs up to size 1.0 occurred in steep Alpine and Treeline terrain on all aspects.

Snowpack Summary

Up to 5cm low density snow fell in the past 24hrs. Previously formed sun crusts on solar aspects are now buried beneath the most recent snow. Wind slabs between 20 and 40cm thick are found in the Alpine and open areas at Treeline, but seem confined to immediately below ridge-crests. The Feb 10th persistent weak layer down 80 to 120cm remains a concern and has been the failure plane for natural and human-triggered slides in the past week.
