    Recent snow is available to be redistributed into thin wind slabs over a hard crust.

    Anywhere a supportive crust doesn't exist at or neer the surface, weak layers deep in the snowpack could still be human-triggered.

Avalanche Summary

No recent avalanche activity has been reported.

Snowpack Summary

Anywhere from 0 to 30 cm of recent, dry snow sits atop a widespread crust at higher elevations. While the surface snow remains moist at lower elevations in most areas.

Deeper in the snowpack a layer of facets (and small surface hoar in some areas) is buried 30-60 cm deep, while a second layer of facets on a crust is buried 80-100 cm deep.

Terrain and Travel Advice

  • When a thick, melt-freeze surface crust is present, avalanche activity is unlikely.
  • Wind slabs may be poorly bonded to the underlying crust.
