  Recent winds and snow have created windslabs up to a meter thick on lee slopes on N- E aspects. These sit on previous windslabs and facetted snow, and are especially touchy in wind effected areas in the alpine.

  The basal facets are more of a concern in thinner snowpack areas east of the divide, and in Kootenay park. Confidence in bigger alpine terrain is still low because of the high winds that have scoured the alpine this year, creating many thin spots.

  10-40 cm of snow has fallen in the last 48h, with the most snow West of the divide. This snow came in warm and is bonding well, but is more reactive in wind effected areas in the alpine and thin areas such as open glades below tree line in Kootenay
