Highlights

Up high, the storm slab problem may still be rider-triggerable. Assess small slopes, before committing to your line.

Rain at lower elevations has made travel difficult.

    Rain may have helped the new snow to bond to the old, but areas that didn't get rain area more likely to see a storm slab problem. Investigate how the snow is bonding to the old.

Avalanche Summary

No new avalanches have been reported since Friday.

Snowpack Summary

New snow is falling on a variety of crystals that it may not bond well to. Including surface hoar in open, sheltered terrain, sun crusts, and wind-affected snow. However, rain at the beginning of the storm may have helped the new snow to stick.

Below the new storm snow, the snowpack is well-settled, dense, and generally strong.

Treeline snow depths range from 100 to 150 cm.
