  Recent strong SW winds have created windslabs up to a metre thick on lee slopes in the alpine (primarily N- E aspects). Although these slabs are starting to settle out with warm temps, it is still possible for a skier to trigger these slabs.

  The warm alpine temp's forecasted may be the straw that broke the cornice's back. If cornices do drop onto lee slopes, it could be a heavy enough trigger to step down into the basal facets. Several natural cornice avalanches were observed today.

  In many areas east of the divide where the snow is shallower the mid-pack overrides a layer of weak basal facets. Be extra cautious of thin snowpack areas where the chance of triggering this layer is highest.
