Avalanche Summary

Several explosive and skier-triggered storm slab avalanches occurred on Sunday, up to size 2, on a variety of aspects and elevations.

If you do go into the backcountry, please consider submitting a MIN report.

Snowpack Summary

Roughly 20 to 30 cm of recent snow has been redistributed by strong northerly winds in the alpine. At treeline and above, in wind-sheltered terrain, the new snow sits atop variable old surfaces, including large surface hoar crystals. In wind-exposed terrain and areas below treeline the new snow sits atop a widespread, thick crust.

The mid and lower snowpack remains well-bonded with no layers of concern.

Terrain and Travel Advice

  • Stay off recently wind loaded slopes until they have had a chance to stabilize.
  • Be aware of the potential for larger than expected storm slabs due to the presence of buried surface hoar.
