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

    Rain at lower elevations will gradually break down surface crusts and contribute to wet snow sluffing and gathering mass in steep terrain.

Avalanche Summary

On Saturday, the main concern is storm and wind slab avalanches where the precipitation has fallen as snow. At tree line and below expect small loose snow avalanches in steep terrain on all aspects.

Confidence

Low - Due to the number of field observations

Weather Forecast

SATURDAY: Snow Friday overnight into Saturday, accumulation 30-40cm / Moderate to strong south wind / Alpine temperature -1 / Freezing level 1000mSUNDAY: Mix of sun and cloud / Moderate southeast wind / Alpine temperature 1 / Freezing level 1300mMONDAY: Flurries / Light to moderate south wind / Alpine temperature 0 / Freezing level 1200m

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.
