    In some areas of thin snowpack there are unconsolidated facets down to the ground. In these areas you may be able to trigger larger than expected dry loose avalanches.

    With new snow totaling up to 30 cm, ski triggerable slabs may exist in steep open areas at all elevations

Avalanche Summary

A notable skier triggered size 1 dry loose that ran to ground on facets (see photo) and sevaral other dry loose to size 1.5 out of steep rocky slopes in the past week.

Snowpack Summary

20-30 cm unconsolidated storm snow over windslabs 20-40cm deep. This overlies the January drought layer which includes facetted snow on northerly aspects or a melt freeze crust below treeline and on steep solar slopes into the alpine. Generally, the snowpack has become weak and facetted.

Snowpack depths at treeline range from 100 - 160 cm.

Weather Summary

The temperature will increase through the forecast period with little to no precipitation.

Terrain and Travel Advice

  • Be aware of the potential for loose avalanches in steep terrain where snow hasn't formed a slab.
