In sintesi

The thin wind slabs created by previous northerly winds are becoming more reactive especially on cross-loaded SW gulleys and bowls at treeline and above. Avoid being on or under terrain with these features.

    Thin cross-loaded slopes at tree line and above are becoming more reactive. Several natural avalanches to size 2 were observed on these features with today's rise in temperatures.

    These slabs are sitting over a weak basal facet layer. Most large avalanches that have been observed recently have been on this layer. The layer is most easily triggered from shallow areas especially along the edge of fatter slopes.
