    Continuous precipitation over the past few days combined with wind at upper elevations has built reactive storm slabs.

    Rain at lower elevations has led to a gradual break down of surface crusts and has contributed to wet snow sluffing and gathering mass in steep terrain.

Confidence

Low - Due to the number of field observations

Avalanche Summary

On Sunday, the main concern is storm and wind slab avalanches where the recent precipitation has fallen as snow. At tree line expect small loose wet avalanches in steep terrain.

Snowpack Summary

Recent snowpack observations have been very limited and confidence is low. The latest series of storms are expected to have brought wet snow to only the uppermost elevations within the region. In these highest elevations there may be as much as 100+cm of new snow accumulation. This more than likely sits on a widespread crust on all aspects and elevations except for north facing terrain in the alpine. At lower elevations, rain has saturated an already wet snowpack.
