  In places without an unstable slab, rain on snow is expected to lead to wet loose avalanches rather than wet slab avalanches. Becoming caught in even a small wet loose avalanche can have substantial consequences. Any place where wet loose avalanches have a long open slope to run on will allow for increased avalanche size to occur.

  Above the rain/snow line, gale force SW winds will drift high intensity snowfall into thick, cohesive slabs. Rapid loading rates are expected to make these wind slabs unstable with the potential for natural avalanches to occur. Any slopes where wind drifted snow is depositing are highly suspect. 

  Travel in, near, or below avalanche terrain is not recommended at this time.

  Snow levels rising to around 8,000' today will put rain on recent new snow. Storm slabs and wind slabs that were reactive yesterday are expected to fail as wet slab avalanches during rainfall today. Wet slab avalanches could occur on any aspect today up to elevations of a couple of hundred vertical feet above the rain/snow line. High density wet avalanche debris can be destructive and very difficult to excavate, increasing the consequences of becoming caught in an avalanche.
