In sintesi

Storm snow is gaining strength, but you should remain wary of solar aspects where the new snow rests on a buried sun crust that may remain sensitive to human triggering.

Problemi valanghivi

  • Cornices

    Dimensione

    Continued snowfall and strong wind from around the clock has formed large cornices on many ridgelines. Cornices are inherently unstable, unpredictable, and demand respect, especially when the sun is out.

    20 to 40 cm of recent snowfall arrived with strong wind. This slab is gaining strength and settling out quickly, but you should remain wary of south facing slopes where up to 100 cm of storm snow rests on an untrustworthy buried sun crust.

Confidence

Moderate - Due to the number of field observations

Avalanche Summary

No recent avalanches have been reported.Check out this MCR report (here) that talks about the strong late winter sun initiating natural avalanches to size 2 on Thursday.

Snowpack Summary

The region picked up 20 to 40 cm of snow Wednesday and Thursday with moderate winds out of the east/southeast. This adds to the 50 to 70 cm that fell earlier in the week. All of this snow rests on previously wind-affected surfaces and a sun crust on southerly aspects.Cornices have formed on many alpine ridgelines. They will become touchier as they grow in size, as temperatures rise, and as they are subject to the strong late-winter sun on clear days.
