Points saillants

Caution on solar aspects as intense solar radiation and high freezing levels are initiating loose wet avalanches out of steeper terrain.  Watch for indications of warm temps such as water on the rocks or pinwheeling of surface snow.

Problèmes avalancheux

    Dense wind slabs are common in Alpine terrain and open areas at Treeline, especially in lee and cross-loaded features. Steep terrain with shallow snowpack characteristics are potential trigger points.

    As temperatures warm up expect to encounter loose wet avalanches on more solar aspects out of steeper terrain.

Confidence

Fair - Freezing levels are uncertain on Saturday

Weather Forecast

Tomorrow temperatures are still expected to be warm with freezing levels up to 2900m.  Winds are forecast to be light out of the north.  No new precip....  That looks a little ways off yet.

Avalanche Summary

Some loose dry avalanches out of steeper terrain up to sz 1 and some loose moist pinwheeling on solar aspects.

Snowpack Summary

The temperatures warmed up today especially at the higher elevations.  -1 was observed at 2500m and some of out weather stations were showing temps of +3 at 2200m.  So long story short, a bunch of different temperatures were observed in the region.  Expect to encounter a sun crust tomorrow morning on solar aspects up to 2600m and dry snow on more polar aspects.
