In sintesi

Minimal new snow, light winds, and cool temperatures in the next few days will not change the danger rating. There have been multiple close calls in the last few days in thin snowpack areas - use caution! See our FB page for pictures.

    Fresh wind slabs up to 50cm thick have been formed in the last 24h from strong W/SW winds. These will be sensitive to skier triggering in the lee of ridge crests.

    Down 70-150cm, the Valentines surface hoar is producing harder shears and showing signs of rounding; however, several natural and skier triggered avalanches over the past few days show that this layer is still a concern.

    Recent snow has covered up thin, scoured areas making them look appealing to riders. There have been multiple remote triggered avalanches in the Louise backcountry in the last two days in thin snowpack areas that have stepped down to the basal facets
