Avalanche Summary

We haven't received any reports of new avalanches, although a few riders reported sluffing in steep alpine terrain. Looking forward, daytime warming will increase the likelihood of wet loose avalanches on sun-exposed slopes. Cornice falls are also possible.

Please consider sharing your observations to the Mountain Information Network.

Snowpack Summary

A wind affected snow surface is found in the alpine. Wind-sheltered terrain may hold settled soft snow. Steep sun-exposed slopes will moisten with daytime warming and freeze into a hard melt-freeze crust overnight.

Cornices are large and looming at this time of year.

Terrain and Travel Advice

  • Pay attention to cornices and give them a wide berth when traveling on or below ridges.
