Avalanche Summary

A large glide slab released naturally on Monday. These natural hazards should be given a wide berth.

Wet and dry loose avalanches continue to be triggered by skiers in the region. These avalanches have occurred in steep terrain on a variety of aspects and elevations.

Snowpack Summary

The upper  snowpack is variable. A crust exists on or near the surface on all aspects below treeline and on all sun exposed slopes.  On high north aspects, Up to 30 cm of snow has buried a thick melt-freeze crust from late March. Below these crusts, the upper snowpack is moist.

The base of the snowpack is generally well settled.

Weather Summary

Precipitation amounts over the next 24hrs could be highly variable due to convection.

Pulses of new snow and fluctuating freezing levels will likely keep wet loose avalanches possible.

Dry loose avalanches are also possible where recent snow hasn't formed a slab or become moist .

Aspects: All aspects.

Likelihood: Possible

Expected Size: 1 - 1.5
