In sintesi

A temperature inversion is forecast for Friday. Temperatures may reach or exceed the freezing mark in the alpine. Ice climbers should consider this especially on routes with south facing overhead hazard, ie loaded snow slopes and/or pillows.

    This layer continues to settle and is becoming less of a concern. Steep cross loaded or lee slopes are likely trigger zones. Alpine snowpack depth remains highly variable. At treeline and below, travel is good.

    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.
