Avalanche Summary

We haven't received any reports of new avalanches. The likelihood of triggering avalanches is low at this time.

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 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

  • The more the snow feels like a slurpy, the more likely loose wet avalanches will become.
  • Pay attention to cornices and give them a wide berth when traveling on or below ridges.

Problems

Loose Wet

Loose Wet avalanches are the release of wet unconsolidated snow or slush. These avalanches typically occur within layers of wet snow near the surface of the snowpack, but they may quickly gouge into lower snowpack layers. Like Loose Dry Avalanches, they start at a point and entrain snow as they move downhill, forming a fan-shaped avalanche. Other names for loose-wet avalanches include point-release avalanches or sluffs. Loose Wet avalanches can trigger slab avalanches that break into deeper snow layers.
