Avalanche Summary

A few small loose avalanches were observed in the region over past few days, generally being triggered by the sun.

Looking forward, small wet loose avalanches could be triggered during periods of sunny skies but they are unlikely to impact riders. Use plenty of caution along alpine ridges, where cornices may be very large.

Snowpack Summary

Around 5 to 10 cm of dry snow overlies a hard melt-freeze crust. The snow may moisten on sun-exposed slopes during sunny conditions.

The remainder of the snowpack is strong with varying hard snow layers and bonded melt-freeze crusts. Cornices are very large along alpine ridges.

Terrain and Travel Advice

  • Pay attention to cornices and give them a wide berth when traveling on or below ridges.
  • Minimize exposure to sun-exposed slopes when the solar radiation is strong.
