Lo esencial
The natural avalanche cycle is over, however skier triggered avalanches are happening daily. Now is the time to be very conservative in the back-country.

A poor bond still exists between the storm snow and the Feb 10 interface. This interface is reactive to skier triggering. (see avalanche details)
Weather Forecast
Friday will be cloudy with isolated flurries. High temperatures in the alpine near -12. Ridge top winds west 10-30 Kph
Snowpack Summary
30 -70 cm of recent storm snow is settling and overrides the Feb 10th interface. A poor bond persists at this interface and many avalanches have been observed on this layer over the past week. Recent SW winds have created wind slabs in lee alpine terrain. These wind slabs are easily triggered and often step down to the Feb 10th interface.
Avalanche Summary
The natural avalanche cycle seems to have subsided, however skier triggered avalanches are still happening regularly. Several skier triggered avalanches (up to class 2) were reported in the Lake Louise on Thursday. Two skier remotes were reported on the moraine approach to Peyto Glacier on Wednesday.
