In sintesi

Forecasted new snow did not materialize. Isolated wind slabs exist in the Alpine and dry loose activity continues. Despite the Low danger rating, safe travel practice is still required especially in high consequence terrain.

    This problem is specific to steep terrain. Activity expected to continue especially on southerly aspects during peak solar. Sluffs may gain enough mass to knock you off your feet as new snow sits over a firm bed surface in most locations.
