In sintesi

A persistent weak layer remains a primary concern for the region
New snow may be forming fresh wind slabs near ridgetops
In times of uncertainty, stick to conservative terrain

Problemi valanghivi

  • Wind Slabs

    • Alta quota
    • Limite del bosco
    • Sotto il limite del bosco
    Probabilità
    Possible - Likely
    Dimensione
    1–2

    New wind slabs may be building at upper elevations on leeward slopes throughout Saturday.

  • Persistent Slabs

    • Alta quota
    • Limite del bosco
    • Sotto il limite del bosco
    Probabilità
    Possible
    Dimensione
    1–2.5

    The persistent layer of large surface hoar/ facets and a crust buried 30 to 50 cm deep is a concern in some areas. There is a lot of uncertainty around how reactive this layer remains as the cooler weather moves in.

Confidence

Low

  • We are uncertain about how quickly persistent slabs are gaining strength.
  • We are uncertain due to a highly variable snowpack.

Avalanche Summary

Thursday

Explosives triggered size 3 and 3.5 slabs near Sliding Mountain in the northeastern part of the region. Numerous size 2 to 2.5 wet loose avalanches were also observed across the entire region.

Wednesday

A widespread natural persistent slab avalanche cycle up to size 2.5 occurred. A few cornice falls were also reported.

Looking Forward

While natural avalanche occurrences are tapering off, human triggering potential remains.

Snowpack Summary

2 to 10 cm of new snow is expected on Saturday. This will bury a melt-freeze crust that is currently capping the snowpack on all but high-elevation northerly terrain.

The late January persistent weak layer, consisting of surface hoar/facets/crust, is currently buried 30 to 50 cm. This layer remains a significant concern, especially in the southern parts of the region.

The mid and lower snowpack is well settled.

Terrain and Travel Advice

  • Stay away from steep slopes, open slopes, and convex rolls at and below treeline where weak layers may be preserved.
  • Watch for newly formed and reactive wind slabs as you transition into wind-affected terrain.
  • Start on smaller terrain features and gather information before committing to bigger terrain.
  • Remote triggering is a concern; avoid terrain where triggering overhead slopes is possible.
