In sintesi

Temperatures and danger ratings are falling.

A supportive surface crust will make avalanche activity unlikely.

Problemi valanghivi

    Large, fragile cornices exist. Be aware of overhead hazard, and stay back from overhanging cornices on ridgelines.

Avalanche Summary

No new avalanches have been reported. However a wet loose cycle likely occurred over the weekend at all elevations.

As temperatures cool, wet loose activity is unlikely. If you are heading into the backcountry, consider sharing your observations and posting a MIN.

Confidence

High

  • We have a good understanding of the snowpack structure and confidence in the weather forecast.
  • We are uncertain due to a limited number of field observations.

Snowpack Summary

Overnight cooling will likely form a widespread surface crust. Beneath the crust, the upper snowpack will remain moist, gradually refreezing as temperatures drop. Dry snow may remain on the highest, north facing slopes spared from the warming.

Several crusts exist 40-70 cm deep. Below this, the rest of the snowpack is wet but well settled and strong. There is little to no snow below 1000 m.

Terrain and Travel Advice

  • Avalanche activity is unlikely when a thick melt-freeze crust is present on the snow surface.
  • Cornices often break further back than expected; give them a wide berth when traveling on ridgetops.
