Issued: Mar 23rd, 2024 4:00PM

The alpine rating is moderate, the treeline rating is moderate, and the below treeline rating is low. Known problems include Persistent Slabs and Loose Wet.

Back off sun affected slopes as snow becomes wet and slushy.

While dry snow may remain on north facing features at treeline and alpine elevations, weak layers are possible to trigger here.




Avalanche Summary

No new avalanches were reported on Friday. Loose wet avalanches were observed from steep solar slopes earlier this week. Avalanches ranged from size 1-2.5, with the larger avalanches scouring to ground.

The last persistent slab activity was reported on Wednesday to size 3. This occurred on south facing alpine slopes likely triggered by daytime warming. Size 2 avalanches were also skier triggered in shallow rocky areas, producing persistent slab avalanches.

Weather Summary

Terrain and Travel Advice

  • When a thick, melt-freeze surface crust is present, avalanche activity is unlikely.
  • A moist or wet snow surface, pinwheeling and natural avalanches are all indicators of a weakening snowpack.
  • Avoid thin areas like rock outcroppings where you're most likely to trigger avalanches failing on deep weak layers.


Persistent Slabs

An icon showing Persistent Slabs

Human triggering remains a concern with buried weak layers. Minimize your exposure to large open slopes, especially on shallower terrain features at alpine and treeline.

Aspects: All aspects.

Elevations: Alpine, Treeline.



Expected Size

2 - 3.5

Loose Wet

An icon showing Loose Wet

The potential for wet avalanches will increase throughout the day with warm and sunny conditions, particularly on steep south-facing terrain. Avoid sun affected terrain as the surface crust breaks down.

Aspects: South East, South, South West, West.

Elevations: All elevations.


Possible - Likely

Expected Size

1 - 2.5
