In sintesi

Up to 40 cm of storm snow overlies a thick hard crust and solar input is likely to trigger avalanches today.

Seek simple terrain and avoid steep sunny slopes.

Problemi valanghivi

  • Storm Slabs

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

    Recent snow may slide easily on a hard, slick, buried crust until we observe otherwise. Avalanches are expected be larger and more likely on west through north facing (leeward) slopes.

  • Loose Wet

    • Alta quota
    • Limite del bosco
    • Sotto il limite del bosco

    Once the sun comes out , expect wet loose avalanches to begin. Even a small wet loose can be harmful when combined with a terrain trap such as a cliff or ditch.

Confidence

Moderate

  • We are uncertain about how the timing or intensity of solar radiation will affect the snowpack.

Avalanche Summary

No new avalanches have been reported.

If you are heading into the backcountry, consider sharing your observations and posting a MIN.

Snowpack Summary

30-50 cm of recent snow is settling above a widespread thick. hard and smooth crust that exists everywhere except the highest alpine terrain. Expect this snow to rapidly become moist and unconsolidated when the sun comes out.

Extreme southwest wind on Tuesday gradually eased to strong and then moderate for Thursday, redistributing the storm snow into leeward terrain, expect slab depths to be deeper there.

Older crust layers, now buried 100 to 200 cm deep, are no longer a concern, and the lower snowpack is generally strong and bonded.

Terrain and Travel Advice

  • Closely monitor how the new snow is bonding to the crust.
  • Be alert to conditions that change with elevation, aspect, and exposure to wind.
