In sintesi

The sun this coming weekend, and with it will come warmer temp's. This will increase the danger on south and west aspects during the day. There have been close calls on these aspects the last few days; check our FB site for pics.

    Fresh wind slabs up to 50cm thick have been formed 2 days ago from strong W/SW winds. These slabs are now hidden by 10-15cm of new snow. These will be sensitive to skier triggering in the lee of ridge crests and in cross-loaded gullies.

    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. East of the Divide, there have been multiple remote-triggered avalanches in shallow snowpack areas that have stepped down to this layer, particularly west aspects.
