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.

Terrain and Travel Advice

  • Keep your guard up as storm slabs may remain sensitive to human triggering.
  • Use small, low consequence slopes to test the bond of the new snow.
  • Make observations and continually assess conditions as you travel.

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.
