Weather Forecast
A largely unsettled cold air mass will bring about convective showers and generally calm winds over the weekend.
Snowpack Summary
Up to 10 cm's of new snow in the high alpine. Intermittent gusty westerlies developing windslabs up to 30cm's in specific areas in the alpine. Firm crusts up to 10 cms thick remain intact at most elevations below the new snow surface.
Avalanche Summary
Some loose dry avalanches have observed in high alpine today up to size 1.5. Small windslabs sitting on the recent crusts are reactive to skier triggering have been reported up on the Wapta Icefield.
