Highlights

A spike in natural avalanche activity may occur due to strong solar effect.

Avalanche problems

  • Wind Slabs

    • Alpine
    • Treeline
    • Below treeline
    Likelihood
    Possible
    Size
    1–1.5
    Wind slabs may have a poor bond to the underlying crust and be reactive at upper alpine elevations. Loose dry avalanches are possible from steep terrain features.

  • Cornices

    • Alpine
    • Treeline
    • Below treeline
    Likelihood
    Possible
    Size
    1–2
    Large cornices have formed and they remain fragile. Cornices are unpredictable and demand respect. Give them a wide berth from above and below.

Confidence

Moderate - Due to the number of field observations

Avalanche Summary

No new avalanches were reported on Friday.

Snowpack Summary

Rain over the past few days has saturated snow surfaces and only higher alpine elevations were lucky enough to get snow. With forecast cold temperatures, the upper snowpack will likely lock up as a firm crust. The average snowpack depth at treeline is 300 cm of well settled snow with no significant layers of concern.
