  Above freezing overnight temperatures with mostly clear skies will allow the snow surface to partially refreeze due to radiational cooling.  As rapid warming occurs this morning, this surface crust will quickly melt and become unsupportive.  Loose wet avalanches will become possible as the snow becomes wet and deep.  E-SE-S aspects will warm and melt the quickest, followed by SW-W-NW-N-NE aspects as the day progresses.  Strong SW winds today may slow melt rates near ridgetops, but expect rapid warming on the slopes below.

  Avoid avalanche terrain once the snow surface has become wet and unsupportive.  Exposed obstacles could pose travel concerns as our snowpack continues to melt out.

  Cornice fall remains a concern throughout the forecast area.  Large cornice collapses could cause injury or trigger loose wet or wet slab avalanches as they load the slopes below.  Avoid traveling on slopes below large cornices.  Along ridges, these cornices can break much farther back from there edges than expected.
