Avalanche Summary

No new avalanches have been reported.

Snowpack Summary

Rain fell on the snowpack below treeline on Thursday. Snow fell at higher elevations, potentially creating new storm slabs. Recent snow overlies variable surfaces including crusts and facets, which are more likely to be problematic on shady aspects. The mid and lower snowpack are generally strong.At treeline and below, a strong spring snowpack exists. Rain may break down surface crusts, but the snowpack is expected to regain strength once the temperature drops again.

Avalanche Problems

Storm Slabs

Storm slabs could be triggered with the weight of a person in alpine areas.

Use conservative route selection: choose moderate angled and supported terrain with low consequence.Minimize exposure during periods of heavy loading from new snow, wind or rain.

Aspects: All aspects.

Elevations: Alpine, Treeline.

Likelihood: Possible - Likely

Expected Size: 1 - 2
