Avalanche Summary

No new avalanches were reported in this region on Thursday. However, field observations are currently very limited.

If you are getting out into the backcountry, let us know what you are seeing by making a post on the MIN (Mountain Information Network).

Snowpack Summary

Up to 30 cm of recent snow can be found at upper elevations and is settling rapidly with intense solar radiation and warm temperatures. Southwest wind may form wind slabs on lee features in the alpine.

The recent snow sits above a crust in most areas. The exception is on northerly aspects at upper elevations where it overlies dry snow.

Expect difficult travel at lower elevations with thin snow coverage.

Terrain and Travel Advice

  • Be alert to conditions that change with aspect and elevation.
  • Watch for newly formed and reactive wind slabs as you transition into wind affected terrain.
  • Watch for signs of instability like whumpfing, hollow sounds, shooting cracks or recent avalanches.
  • When a thick, melt-freeze surface crust is present, avalanche activity is unlikely.
