Lo esencial

A reactive persistent weak layer remains the primary concern for the region - especially around treeline.

Stick to low-angle slopes and avoid overhead hazards.

Problemas de aludes

  • Wind Slabs

    • Alta montaña
    • Límite del bosque
    • Bajo el límite del bosque
    Probabilidad
    Likely
    Tamaño
    1–2

    New snow and wind will be buiding fresh wind slabs near ridgetops and on lee and crossloaded features at upper elevations.

  • Persistent Slabs

    • Alta montaña
    • Límite del bosque
    • Bajo el límite del bosque
    Probabilidad
    Likely
    Tamaño
    1.5–3

    Be aware of the potential for remote triggering and large avalanches due to buried surface hoar or crust, especially at treeline and forested openings or cutclocks.

  • Loose Wet

    • Alta montaña
    • Límite del bosque
    • Bajo el límite del bosque
    Probabilidad
    Possible - Likely
    Tamaño
    1–1.5

    Rain at lower elevations on Wednesday may create potential for wet loose sluffing, especially in steep terrain. Use appropriate sluff management techniques if the snow surface is wet.

Confidence

Moderate

  • We are confident that there are persistent slabs in the snowpack, but uncertain about how likely they are to trigger.

Avalanche Summary

Monday
A size 2 natural cornice failure occurred.

Sunday
Numerous natural, explosive, and rider-triggered avalanches were observed, including a size 2.5 avalanche triggered from 3 m away.

Saturday
A widespread avalanche cycle to size 3 occurred with avalanches failing within the recent storm snow and on persistent weak layers. Many avalanches were in steep open features; however, this MIN from Silent Pass reports a size 2.5 persistent slab avalanche below treeline.

Snowpack Summary

Around 5 to 15 mm of precipitation is in the forecast for Wednesday, and may fall as rain below 2100 m.

Widespread wind effect at upper elevations left a variety of pressed surfaces, slabs, and sastrugi in open terrain. Solar-facing slopes and lower elevations likely have a surface crust.

A persistent weak layer of surface hoar or crust is buried 40 to 60 cm, with deeper areas like the Dogtooth Range reporting this layer up to 100 cm deep. Recent persistent slab avalanches have failed on this layer, many triggered in sheltered openings at treeline and below.

The mid and lower snowpack are generally well settled. In shallow snowpack areas, large facets or depth hoar are present at the bottom of the snowpack.

Weather Summary

Tuesday Night
Mostly cloudy. 2 to 5 cm of snow, highest amounts for the Dogtooth range. 40 km/h southwest ridgetop wind. Treeline temperature -3 °C. Freezing level 1800 m.

Wednesday
Mostly cloudy. 2 to 10 cm of snow at treeline, possible rain below. Highest amounts for the Dogtooth range. 30 km/h southwest ridgetop wind. Treeline temperature -1 °C. Freezing level 2100 m.

Thursday
Mix of sun and clouds. 40 km/h west ridgetop wind. Treeline temperature -5 °C. Freezing level 1700 m.

Friday
Mix of sun and clouds. 40 km/h west ridgetop wind. Treeline temperature -3 °C. Freezing level 1900 m.

Terrain and Travel Advice

  • Watch for newly formed and reactive wind slabs as you transition into wind-affected terrain.
  • Watch for signs of instability like whumpfing, hollow sounds, shooting cracks, or recent avalanches.
  • Be aware of the potential for remote triggering and large avalanches due to buried surface hoar.
