    Be cautious of wind slab in immediate lee and cross-loaded terrain in the alpine. Watch for when it changes from soft to firmer wind affected snow.

Weather Forecast

The next few days winds will remain light westerly, -5 to -15 degrees, and no new significant snow. Friday may bring 5-10cm.

Snowpack Summary

The weekends 30cm of storm snow has formed soft slabs in lee features on a buried crust. The crust can be found 2100-2600m down 40-60cm on all aspects. It will be a layer of concern as the snow load increases. In many areas the storm snow remains unaffected by the wind and offers good skiing. The status quo will remain for a few days longer.

Avalanche Summary

Several size 1-1.5 loose snow avalanches from 2100-2400m on solar aspects were noted on Tuesday through the Icefields. Monday, a size 2 and 1.5 windslab was noted from steeper terrain. The 1.5 was triggered by a group of skiers from 25m away on a west facing slope at 2300m. The other from a NE moraine band at 2100m.
