Points saillants

Outflow winds are building new winds slabs on atypical slopes.

Actively look for signs of instability and identify wind slabs, listen for drum like sounds and hollow sounding snow.

    Strong to extreme winds have heavily impacted the alpine and open treeline terrain. Outflow winds are redistributing any remaining dry snow, building new wind slabs over hard previous surfaces.

Avalanche Summary

No new avalanches reported.

Going forward, wind slabs remain possible to human trigger and may be found on atypical slopes.

Snowpack Summary

Heavily wind affected surfaces in all open terrain features at all elevations. Recent outflow winds developing wind slabs on atypical slopes due to reverse-loading.

A mid-February crust or facet layer sits 50 to 70 cm deep, and the late January crust/surface hoar layer is buried 50 to 100 cm deep.

Facets or depth hoar exist at the base of the snowpack and may be a concern in the inland side of the region, where the snowpack is generally shallower.

Terrain and Travel Advice

  • Watch for newly formed and reactive wind slabs as you transition into wind-affected terrain.
  • Watch for areas of hard wind slab on alpine features.
  • Pay attention to cornices and give them a wide berth when traveling on or below ridges.
