Avalanche Summary

No notable recent avalanches have been reported in the region. In neighboring regions, several natural wet loose and wet slab avalanches were reported to size 2.5 on Monday. If you head into the backcountry you will likely see evidence of an avalanche cycle from the weekend.

Please continue to post your observations and photos to the Mountain Information Network.

Snowpack Summary

Above 1400 m 10 -20 cm of snow sits atop the thoroughly saturated snowpack below it.

As freezing levels drop expect to find a wet snowpack quickly becoming uniform and cohesive. Until then watch for unstable snow on specific features, when snow is moist or wet.

Prior to this weekend's rain event, the snowpack was well settled with treeline depths 100-180 cm.

Terrain and Travel Advice

  • Watch for fresh storm slabs building throughout the day.
  • Carefully monitor the bond between the new snow and old surface.

Avalanche Problems

Storm Slabs

New snow and strong southerly winds have built fresh storm slabs above a saturated snowpack. Storm slab size and sensitivity to triggering will increase as snow accumulates throughout the day.

Aspects: All aspects.

Elevations: Alpine, Treeline.

Likelihood: Possible

Expected Size: 1 - 2
