    The sensitivity of this layer is directly related to heat. Solar radiation and high air temps will cause a very quick  breakdown of the snowpack. Watch the freeze quality from the night before and monitor temps as the day goes on.

Confidence

Good

Weather Forecast

Flurries will bring more snow over the next 24hrs. Amounts are only expected to be around 6cm due to the rapid settlement. Winds will be light from variable directions. Freezing levels will vary from 1600m to 2100m for the next 3 days. Some sun is expected as the front clears off. Expect very strong solar effect and a rapid rise in air temp when this happens.

Avalanche Summary

One large avalanche was noted today that occurred sometime during the storm. It appeared to be a large size 2, but the start zone was obscured.  NE asp, 2350m, wet slab. When the sun made a brief appearance today there was immediate pin wheeling from steep solar aspects.

Snowpack Summary

The new snow has settled significantly in the past 24hrs. Today alone, we witnessed 20cm of storm snow settle to 15cm's within an hour. At all elevations the entire snowpack is moist. Below 2000m, the afternoon heat is turning the snowpack isothermal. In the alpine, the storm slabs are found in immediate lee areas and are  well bonded to underlying surfaces. No wind effect at treeline or below.
