Avalanche Summary

A few loose dry and soft slab avalanches to size 1.5 have been triggered naturally and by skiers over the last couple of days.

Snowpack Summary

Recent snowfall amounts and winds have been variable across the region. Around 15-35 cm snow overlies old surfaces buried on Jan 23. Preserved surface hoar up to 21 mm in size has been found in the North Elk Valley, buried by about 15 cm of snow. It doesn't appear to be a widespread layer, but could be a localized problem once buried with further snowfall. The most wind-affected areas, including Crowsnest Pass and Harvey Pass, have scoured south and west-facing slopes. Wind slabs may be found on lee slopes.
