Watch for reactive slabs at all elevations due to new snow and wind; avalanche danger may vary across the region. Assess local conditions frequently as snowfall amounts are uncertain.

Confidence

Moderate

Avalanche Summary

No avalanche activity has been reported in the region, however, this MIN report suggests that the recent storm snow may be settling into reactive slabs in areas.

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

Snowpack Summary

New snow continues to accumulate across the region, burying a variety of surfaces. These include firm, wind-affected snow at higher elevations or exposed terrain. The new snow may have buried a layer of surface hoar in wind-sheltered terrain and lower elevations.

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.
