Avalanche Summary

A few isolated, small (size 1) wind slabs were triggered by riders on Monday. Otherwise, no new avalanches were observed. There's a low likelihood of triggering avalanches at this time.

Snowpack Summary

Around 2 to 10 cm of settled snow may remain dry on northerly aspects in the alpine. Elsewhere, a surface melt-freeze crust exists.

The remainder of the snowpack is strong.

Terrain and Travel Advice

  • Small avalanches can have serious consequences in extreme terrain. Carefully evaluate your line for wind slab hazard before you commit to it.
  • When a thick, melt-freeze surface crust is present, avalanche activity is unlikely.
  • Carefully evaluate steep lines for wind slabs.
  • The more the snow feels like a slurpy, the more likely loose wet avalanches will become.
