Be alert for wind slab formation, as recent low-density snow can be easily transported and redistributed by strong winds at higher elevations.

Moderate

Avalanche Summary

No recent avalanche activity has been reported.

Observations remain limited this early in the season. If you head into the backcountry, please post to the Mountain Information Network

Snowpack Summary

New, low-density snow continues to accumulate across the region, burying a variety of surfaces. These include firm, wind-affected snow at higher elevations or exposed terrain, and settled powder, with a chance of surface hoar at lower elevations or in wind-sheltered terrain.

Various melt-freeze crusts can be found in the lower snowpack, which are not concerning avalanche layers at the moment.

Snow depths at treeline roughly vary from 80 to 150 cm, and decrease rapidly at lower elevations.

Terrain and Travel Advice

  • Be careful with wind-loaded pockets, especially near ridge crests and rollovers.
  • Watch for signs of slab formation throughout the day.
  • Closely monitor how the new snow is bonding to the old surface.
  • Be cautious of buried obstacles, especially below treeline.

Problems

Wind Slabs

An icon showing Wind Slabs

New, low-density snow may form slabs at higher elevations, where it can be easily redistributed into small wind slabs. In sheltered terrain, as snow accumulates, it could become unstable if it settles on surface hoar crystals.

Aspects: All aspects.

Elevations: Alpine, Treeline.
